1. INTRODUCTION AND ASSEMBLY

1.1 Description of humiFog

humiFog is a humidiﬁer and adiabatic cooler that atomises demineralised water into very ﬁne droplets that evaporate spontaneously in the air, which is humidiﬁed and cooled.

humiFog uses a volumetric pump to pressurise the water, which is atomised by special stainless steel nozzles.

The sophisticated control system combines the action of an inverter, which controls the speed and consequently the ﬂow-rate of the pump, with a series of solenoid valves that activate only the nozzles that are necessary, allowing the system to always operate at the ideal pressure to atomise the water, across a wide range of ﬂow-rates (a 5-100 % ﬂow range working with a constant pressure of 14-100% for operating while controlling the ﬂow).

The eﬀect of cooling the air is due to the spontaneous evaporation of the droplets of water: the change in state from liquid to steam occurs by subtracting energy from the air that, as a consequence, is cooled. Each kilogram of water evaporated absorbs 0.69 kWh of heat from the air.

humiFog is a complete humidiﬁcation and/or adiabatic cooling system that can be used both in AHUs (air handling units) and to humidify or cool industrial environments by spraying water directly into the environments. The term zone refers to both AHUs and industrial environments.

1.2 Components in the system

humiFog is made up of:

• a pumping unit that delivers the water at high pressure (25-70 bars).

It also contains the electronic controller that completely manages the pumping unit, controlling the temperature/humidity in a zone (either AHU or environment) and managing any other zones connected to the pumping unit;

• The pumping unit can be set to operate:

- with ﬂow control (maximum precision, minimum energy and water

consumption, only single zone applications);

- at constant pressure (suitable for multizone applications where one

pumping unit supplies the humidiﬁcation and/or cooling system in diﬀerent zones);

• distribution and atomisation system: system of pipes carrying the

pressurised water that house the atomisation nozzles and, in general, the capacity-control solenoid valves and drain solenoid valves;

• droplet separator (only when installed in an AHU);

• temperature and/or humidity probes (if necessary);

• water treatment system: typically this is a reverse osmosis demineraliser

that supplies water with a low mineral salt content to the humiFog.

1.3 humiFog system conﬁgurations

The humiFog system can be used in the following conﬁgurations:

• single zone: for humidiﬁcation and/or cooling applications in a AHU or

an industrial environment;

• multizone: for applications where one pumping unit (master) is

used to supply multiple zones with pressurised water. The master will control one zone, in the sense that in relation to the zone probe readings or the external controller, it will activate and control the distribution and atomisation system so as to maintain the humidity or temperature level. All other zones will have a controller (slave electrical panel) that communicates with the master, and in relation to the zone probe readings or the external controller will activate and control the distribution atomisation system so as to maintain the humidity or temperature level.

One important conﬁguration is for indirect adiabatic cooling applications: a pumping unit can be used to humidify the air in winter and to cool the discharged air in summer before it enters a heat recovery unit. This conﬁguration is explained in detail in the chapters below.

humiFog humidiﬁers are available for:

• maximum ﬂow-rates respectively of 100 l/h,(UA100..) 200 l/h (UA200..),

320 l/h (UA320..), 460 l/h (UA460..), 600 l/h (UA600..);

• type of cabinet: H=single zone master; Z=multizone master; S=slave

cabinet;

• power supply voltage: D= 230 V 50 Hz; U= 208 V 60 Hz;

• shows the version of the launched product (1 - 4)

• damper: 0=without damper; 1=with damper (only versions with 100

and 200 l/h ﬂow-rate)

• features of the pump and circuits: 0= brass; 1=stainless steel; 2=

stainless steel, silicon free

1.4 Supply water characteristics

Why does humiFog require demineralised water?

Humifog only works with demineralised water, to ensure:

• minimum maintenance;

• no blockage of the nozzles;

• no dust (the droplets that evaporate do not leave mineral salts in the

AHU/environment);

• more hygiene.

The use of demineralised water is also required by standards such as UNI8883 , VDI6022, VDI3803

humiFog must only be supplied with treated water, based on the limit values listed below. In normal circumstances, this means that the water must be treated using a reverse osmosis system.

1.5 Periodic checks for consumables

Summary table of checks and maintenance:

Pump Check/Replace monthly every 1000 h

Water ﬁlters X Oil level X Replace oil X Check/replacement gasket and valves X

Attention: after the ﬁrst 50 h of exercise you need to replace the oil pump.

Attention: if the “1000h” check does not identify any leaks or

malfunctions, then the possibility to postpone the replacement shall be assessed. Typically, in optimum operating conditions, this process is necessary around 3000 h of operation.

Rack/distribution system visually check every 1000 h

obstructed nozzles X solenoid valves X accessories X drain and water X droplet separator X

Tab. 1.b

Installations in AHUs or ducts must also comply with national maintenance standards (ASHRAE 12-2000, VDI 6022, UNI 8884, VDI 3803, etc.)

Please note that:

• maintenance personnel must reset the hour counter after having

performed the preventive maintenance operations listed in the columns “after 50 hours” and “every 1000 hours”. If the hour counter is not reset, the maintenance warnings will no longer be signalled (to reset the hour counter, see the information under Section 9.8 Maintenance menu/submenu f/screen 02);

• maintenance personnel are responsible for any malfunctions due to a

lack of preventive maintenance. The controller will display maintenance warning code “C5” after the ﬁrst 50 hours and, subsequently, routine maintenance warning code “CL” every 2000 hours, as a reminder for the operations listed;

• failure to change the oil after the ﬁrst 50 hours of operation may cause

oil leaks and serious damage to the pumps, reducing operating life;

• maintenance signals do not stop the operation of humiFog.

2. WATER CIRCUIT CONNECTIONS

2.1 Water circuit installation: instructions

The water connections are

•

water inlet;

• high pressure water outlet to the rack (see ”connecting the cabinet to

the rack” in the distribution manual);

• water drain.

Water circuit installation: instructions

To simplify installation and maintenance, install a manual valve immediately before connecting the water inlet to the cabinet (this valve is not supplied by CAREL). humiFog only operates on demineralised water, preferably from a reverse osmosis system. The speciﬁcations and the limits of the water are described in detail in chap. 1.4 “supply water characteristics”.

1. open the water circuit (vedi par. 1.10 “Opening the cabinet door”):

2. connect the water supply hose:

• the supply hose connection ﬁtting is G1/2”F (NPT1/2”F - UL 60 Hz

version).

• the inside diameter of the supply hose must not be less than

13 mm.

• run the water supply hose through hole “3” Fig. 1.a.

Water drain connection

1. connect the drain “5” Fig. 1.a to the drain system:

• use a hose with inside diameter 10 mm, resistant to demineralised

water.

• connect the hose to the drain connection underneath the cabinet

using a hose clamp.

N.B.: the hose and the clamp are not supplied by CAREL, to

tighten clamp, lift the cabinet.

2. connect the drain bypass “6” Fig. 1.a to the drain system.

Replacing the top oil cap on the pump

1. replace the top oil cap on the pump:

• replace the TOP oil cap ( (Fig. 2.a, A), used for transport only, with

the CAP WITH THE VENT HOLE (Fig. 2.a, B) used in normal operation;

• keep closed cap for future transport.

2. reposition the front panel on the water circuit and close it.

3.12 Backup/rotation (redundancy)

The backup/rotation function on two master cabinets allows two pumping units to be used with one single zone and consequently one rack distribution system. The backup function guarantees continuous production when the cabinet that is currently operating shuts down due to an alarm. The rotation function distributes the number of operating hours equally between the two cabinets.

Electrical connections:

Connect the two pumping units according to the following diagram. To complete the electrical connections in backup & rotation mode, a special junction box with relays (P/N UAKDERBK00) must be installed in the system.

Backup box UAKDERBK00

Fig. 3.v

Software conﬁguration: access B. Installer menu > b. Zone settings > c. Special functions.

1. On screen Bbc08, enable the backup function by selecting the

priority to attribute to the cabinet when starting. One cabinet must be set as the “Primary cabinet”, while the other must be set as the “Secondary cabinet”. This conﬁguration is needed to deﬁne the priority of the cabinet that will attempt to start ﬁrst when both units are powered on together. Aside from this, there is no functional diﬀerence between the two units.

2. If deciding to enable rotation between the cabinets, set the “Rotation”

parameter on screen Bbc08 to “YES”, and select the number of pump operating hours before activating the rotation request (default 8 h). .

A system conﬁgured in this way will therefore comprise one cabinet that is operating and one in standby. The cabinet in standby will display “Oﬀ from backup” on the main screen if rotation is not enabled, or “Oﬀ from rotation” if awaiting the time set for rotation.

Important:

• The input signals (external control signal, probes, etc.) must be

connected to both cabinets.

• The operating parameters for the two master units (rack parameters,

number of steps, branch ﬂow-rates, etc.) must be conﬁgured in the same way.

• A “T” connector must be installed in the water circuit to connect the

two pump outlets to the one rack supplied by both units. A nonreturn valve also needs to be installed on the outlet of each pump (P/N UAKCHV****) upstream of the “T” and the main line drain valve (UAKCD0000*).

• If rotation is not enabled, the cabinet that requested changeover due

to an alarm with shutdown can only be reactivated following to an alarm with shutdown on the cabinet that replaced it, even if the alarm condition that caused the unit changeover has been resolved.

• When rotation is enabled, in the event of unit changeover due to an

alarm, the rotation hour counters are reset and the next request is ignored.

• The two pumping units must belong to the same zone and use the

same rack. In multizone conﬁgurations, the backup of the master cabinet (pumping unit that supplies the water line for all the zones) can be implemented, but it will not be possible to have a backup on the slave cabinets.

For further information and details regarding water circuit and electrical installation of humiFog in Backup & Rotation mode, see the oﬃcial document +050004015 +LEAF INSTAL.

3.13 Expansion mode/remote actuator

Expansion

The Slave (UA***S****) cabinets can be conﬁgured on the Bbc01 screen as Expansion/Remote actuators.

This mode transforms the cabinet in an I/O expansion for another Humifog generic cabinet (pumping station or slave) in order to:

• Provide a tool to simplify the wiring if the rack is too far from the

pumping station (Remote Actuator)

• Allow the slave cabinet to use a rack with 6 NC valves on step 1 and 4

NC valves on step 4.

ENG

“humiFog multizone - pumping unit” +0300066EN - rel. 1.2 - 10.12.2015

Remote rack actuator

This mode allows you to control the solenoid valves of the rack in the area associated with the pumping station via one or two “remote area” cabinets controlled in serial sequence via the J23 port of pCO5+. This conﬁguration is particularly useful if the rack is located away from the pumping station, since it allows to bring the control signal via the only serial cable in the rack area, reducing the number and length of the cables of the solenoid valves between the rack and the device that physically controls it (the remote area cabinet).

To enable the function, proceed as follows:

Electrical connections:

• Connect the expansion (or two expansions) serially in port J23 of the

pCO5+ as follows:

FBJ/J23

BMS2

pCOe

Fig. 3.w

• Connect the control signals used for the cabinet conﬁgured as “Remote

expansion/Actuator 1”

• Connect the solenoid valves to the remote area cabinet that controls

them. If two cabinets are used, distribute them evenly. For example, in the case of the ﬁrst step with 6 collectors, connect three solenoid valves to the ﬁrst expansion cabinet and three solenoid valves to the second cabinet.

Software conﬁguration:

• On the pumping station, enable the use of the remote actuator on

the Bbc09 screen: the software automatically establishes the number of required actuators (1 and 2) based on the number of collectors

present, and alerts the user via a dedicated pop-up window Conﬁgure the ﬁrst slave as “Expansion/Remote actuator 1” and the second one (only at request) as “Expansion/Remote actuator 2”

Note: if you are using this mode, the probe readings of the main control (U1), limit (U2), auxiliary (U3), heat recovery signal (U5), rack temperature (U8) and the ventilation solenoid valve are transferred to the remote area cabinet conﬁgured as “Expansion/Remote actuator 1”.

Remote area expansion

The software installed on the remote area cabinet, based on the number of set collectors, automatically determines whether it is necessary to add a second cabinet, used as an expansion for the proper management of the solenoid valves. The system is pre-conﬁgured based on the number of set collectors. The following are necessary to enable the feature: Electrical connections:

• Connect the J23 port of the remote area cabinet that requires

expansion to the BMS2 port of the cabinet conﬁgured as expansion, as follows:

• Connect the adjustment probes and the ventilation valve (if present)

to the remote area cabinet and distribute the solenoid valves between the two cabinets. For example, in case of a step with 6 solenoid valves, connect three to the ﬁrst cabinet and three to the second cabinet.

Software conﬁguration:

• The remote area cabinet, based on the number of set collectors,

establishes if it is required to expand and alerts the user via a dedicated pop-up window

• Conﬁgure the slave used for the expansion as “Expansion/Remote

actuator 1”

3.14 Master-slave connection

The multi-zone master-slave conﬁguration is serial and done through optically-isolated integrated Field-bus 485 present in the humiFog unit.

4.2 Pumping unit with constant pressure control

The humiFog controller manages the water pressure generated to ensure it remains at a constant level, typically 70 bars.

This conﬁguration is used in the following applications:

• humidiﬁcation and/or adiabatic cooling (direct) in an AHU (the ﬂow

control conﬁguration is recommended);

• humidiﬁcation and indirect adiabatic cooling in an AHU ﬁtted with

heat recovery unit (the two distribution systems can atomise water at the same time);

• humidiﬁcation and/or adiabatic cooling (direct) in an industrial

environment;

• humidiﬁcation and/or adiabatic cooling (direct) in multiple zones,

whether AHUs, AHUs ﬁtted with heat recovery units, industrial environments, or any combination of these.

Note that in the case of humidiﬁcation and/or cooling adiabatic directly into rooms, constant pressure control is preferred over ﬂow control: as the droplets are atomised directly into the environment, to minimise the space required for evaporation, the smallest possible diameter should be achieved and therefore the water must be atomised at maximum pressure. This is represented by constant pressure control, which maintains the pressure at 70 bars.

humiFog is ﬁtted with an inverter to control the speed of the pump and maintain the pressure at the rated value set by parameter, typically 70 bars.

The humiFog system will be made up of a pumping unit (master) that also controls its own zone, as well as a series of zone electrical panels (slaves) corresponding to the number of remaining zones. Note that for humidiﬁcation and indirect adiabatic cooling in an AHU ﬁtted with heat recovery unit (the two distribution systems may atomise the water at the same time) a zone panel (slave) will be required.

The groups of nozzles are normally conﬁgured when selecting the humiFog system, and the procedure is clearly described in the documents supplied with the water distribution system (rack or room distribution and atomisation system)

Constant pressure control rationalises operation of the humiFog pumping unit as, despite the lower precision, it can treat a number of zones at the same time without installing a pumping unit for each AHU or industrial environment.

4. PUMPING UNITS

4.1 Pumping unit with ﬂow control conﬁguration

humiFog controls the humidiﬁcation and/or cooling capacity by continuously controlling the atomised water ﬂow-rate across a wide range of modulation.

This conﬁguration is used in the following applications:

• humidiﬁcation and/or adiabatic cooling (direct) in an AHU;

• humidiﬁcation and indirect adiabatic cooling in an AHU with heat

recovery unit (one atomisation system at a time atomises the water). In this case, a zone electrical panel will be required, see the next chapters for further information.

humiFog is ﬁtted with an inverter to continuously and precisely control the speed of the pump and, consequently, the ﬂow-rate.

The outlet pressure is kept within the optimum water atomisation limits by the range of modulation of the pump speed and control of the number of nozzles that atomise the water.

In detail, the nozzles must be supplied at a pressure in the range from 25 to 70 bars, to ensure that the droplets generated have an average equivalent diameter of 10-15 µm.

Based on the ﬂow-rate of water to be atomised, humiFog will activate the number of nozzles that ensures the pressure is within the range indicated above.

It is clear that if the required ﬂow-rate is low, just a few nozzles will be needed to atomise the water; if the request increases, the increase in ﬂow-rate will cause an increase in pressure that, if it exceeds 70 bars, will activate other atomising nozzles, consequently decreasing the pressure and returning it within the range of optimum values. Similarly, if the humidiﬁcation request decreases, the ﬂow-rate and thus the pressure will decrease and, if the latter falls below 25 bars, some nozzles will be closed so that the pressure returns within the optimum atomisation range. This is possible because the nozzles are assembled into groups of up to four, with diﬀerent capacities; when suitably activated, these guarantee continuous modulation of the ﬂow-rate across a wide range, nominally from 14 to 100% of the maximum ﬂow-rate, with a pressure from 25 to 70 bars.

The groups of nozzles are normally conﬁgured when selecting the humiFog system, and the procedure is clearly described in the documents supplied with the water distribution system (rack).

The pumping unit in the ﬂow control conﬁguration can only be used for single-zone applications: one pumping unit supplies just one zone at a time. Multizone conﬁgurations are not possible.

The ﬂow control conﬁguration guarantees maximum humidiﬁcation and adiabatic cooling precision as capacity is controlled continuously and across a wide range.

5. DISTRIBUTION SYSTEM

This paragraph brieﬂy describes the distribution and atomisation systems for AHUs (rack and droplet separator) and for rooms. These are described in detail in the “humiFog – distribution systems” manual.

5.1 Air handling unit: distribution, atomisation system and droplet separator

The rack is supplied made-to-measure based on the AHU/duct and is made up of various vertical manifolds with atomisation nozzles, each with activation and drain solenoid valves. Each rack is also ﬁtted with a main drain solenoid valve installed at the lowest point of the piping that connects the rack to the pumping unit. In addition, it is ﬁtted with a vent solenoid valve on the horizontal manifold so as to completely empty the pipelines. The manifolds house the required number of atomising stainless steel nozzles located in speciﬁc positions, calculated during the system conﬁguration phase and described in the documents supplied with the rack.

The droplet separator has the purpose of trapping the droplets of water that are not completely evaporated, so as to prevent objects located downstream from getting wet. The droplet separator is supplied in standard modules that can be assembled on a support structure to cover the cross-section of the AHU. The structure is always in stainless steel, and guarantees fast and eﬀective draining of the water trapped by the droplet separator. The modules are available with glass wool or stainless steel ﬁlters, the latter required for hygiene-certiﬁed installations, such as VDI6022, UNI8884, etc.

The width and height of the rack and the droplet separator vary with approximately 152 mm within the following limits:

• width: 508…2,788 mm;

• height: 516…279 mm.

If the droplet separator does not exactly cover the cross-section of the AHU, the free spaces must be sealed to prevent air from bypassing the droplet separator.

Flexible or stainless steel hoses are supplied for connecting the pumping unit to the rack.

Note that a droplet collector tank with drain connection must also be ﬁtted, containing the rack, droplet evaporation chamber and droplet separator. This tank is not supplied by CAREL.

5.2 Direct humidiﬁcation into the room: distribution and atomisation system

This system consists of

• hoses and/or stainless steel pipes for the distribution of pressurised

water;

• capacity-control solenoid valves to shut oﬀ the branches of the system

that don’t need to atomise water (on/oﬀ operation, N.C.);

• drain solenoid valves to empty the installation and prevent stagnation

of water (on/oﬀ operation, N.O., opening pressure 13 bars);

• main drain solenoid valve installed on the lowest point of the piping

that connects the rack to the pumping unit, so as to completely empty the system and avoid stagnation of water. The solenoid drain valves are also used to quickly discharge water pressure when the line stops atomising, avoiding dripping. In addition, the solenoid drain valves are used for the automatic periodical washing function managed by humiFog;

• stainless steel manifolds (pipes with holes) with atomising nozzles;

• blower units: compact units featuring manifolds with atomising

nozzles, on-oﬀ solenoid and drain valve, plus a fan that creates a stream of air that carries the droplets and ensures they evaporate completely before falling in the environment.

The distribution and atomisation system can have up to 6 capacity modulation steps, where, obviously, each step can have a series of branches with pipes, manifolds and/or blower units.

Special attention must be paid to the position of the nozzles and the blower units inside the environment: observe the installation limits (minimum installation height and minimum horizontal distance from objects/machinery/people that must not be wetted), as shown in the “humiFog multizone: distribution system” manual.

6. APPLICATIONS

humiFog for AHU/ducts is suitable for all applications in which the air can be humidiﬁed and/or cooled adiabatically, atomising demineralised water. Below are some possible applications of humiFog:

• oﬃce buildings

• hotels and call centers

• printing and paper industries

• cleanrooms

• libraries and museums

• textiles industry

• food industry

• direct/indirect adiabatic cooling

• timber industry

• other industrial applications.

The possibility of using an atomising rack for indirect adiabatic cooling is especially interesting: the air to be discharged is cooled adiabatically (bringing it to saturation) and is then used to cool the fresh outside air using an air-air heat exchanger, as shown in the following ﬁgure.

Tab. 6.a

*: In accordance with H6020 (02/07), chapter 6.13.2 the use of steam humidiﬁers or equivalent humidiﬁcation systems is required in Austria.

Please note:

Further advantages of the humiFog system include:

• extremely low electricity consumption: around 4 Watts for each litre/

hour of humidiﬁcation capacity;

• high maximum capacity: 600 kg/h (customised versions are available

with capacities up to 5000 kg/h);

• high precision, thanks to models with continuous modulation from

14% to 100% of maximum capacity;

• complete distribution rack, supplied already assembled and tested;

• extremely ﬁne atomisation with consequently very little space required

for evaporation, due to high water pressure (25 to 75 bars);

• optimum humidiﬁcation and cooling eﬀect in the AHU thanks to

custom racks made to measure based on the cross-section of the AHU;

• very low maintenance requirements

• automatic washing and emptying cycles to avoid stagnation of water

• no dripping;

• silent nozzles

• modularity: one pumping unit can supply up to 6 zones

• connectivity: humiFog can be connected to external systems, for

example BMS, using the MODBUS, TCP/IP protocols etc. (see paragraph

3.10).

7. CONTROL

The electronic controller ﬁtted in the humiFog features diﬀerent control algorithms, which can be selected from the installer menu.

• HH control:

modulates the capacity (water ﬂow-rate) using two humidity probes, one control probe normally installed in the AHU in the return air, and one limit probe, usually installed downstream of the droplet separator.

• HT control:

modulates the capacity (water ﬂow-rate) with two probes, one humidity control probe and one limit temperature probe. This conﬁguration is recommended for systems in which a certainly humidity level is required without however excessively cooling the air.

• H control:

like the HH algorithm but without the limit humidity probe;

• TH control:

modulates the capacity (water ﬂow-rate) with a temperature probe normally installed in the AHU in the return air, and a limit humidity probe, usually installed downstream of the droplet separator. In room applications, both probes are installed so that the temperature and relative humidity represent the average ambient values (for example, not near windows or the nozzles where the cooling and humidiﬁcation eﬀect do not correspond to the averages in the room)

• TT control:

modulates the capacity (water ﬂow-rate) with a temperature control probe and a limit temperature probe. This conﬁguration is recommended for adiabatic cooling systems in rooms where the control probe is usually installed in the centre of the room and the limit probe at another “critical” point where the temperature must absolutely not fall below a set limit value.

• T control:

like the TH algorithm, but without the limit humidity probe;

• CH/CT control:

operation in on/oﬀ mode, based on a voltage-free external contact (for example, a humidistat). The capacity will thus be either the maximum set or nothing, depending on the status of the external contact, and is limited based on the value measured by the limit probe.

• C control:

like the CH/CT algorithm but without the limit probe;

The HH and TH algorithms are the most commonly-used, and recommended for humiFog installations.

The limit humidity probe described above is usually set to high values, e.g. 80% rH, so as to limit the maximum moisture in the air introduced into the duct and into the room. This is especially recommended in installations where air ﬂow-rate and operating, temperature and humidity conditions, may change over time and, consequently an additional safety system is required to prevent the humidiﬁer from over-humidifying the air and, in the worse case scenario, condensing in the ducts downstream.

7.2 Evaporative Cooling

If optiMist is used as an application dedicated to evaporative cooling, the possible controls are:

• TT Control

• TH Control

• TF Control

• T Control

• PH/PT/PF Control

• P Control

• C Control

• CH/CT/CF Control

IMPORTANT: All of these controls require a consent signal that lets the humidiﬁer know when it can operate. This indication corresponds with the activation of the recovery unit in the Air Treatment Unit (ATU); this information can be sent to the humidiﬁer through:

• a modulating 0-10V signal (corresponding to the opening of the

renewal air locks) or

• a digital contact or

• a digital variable via supervision (DIG 63).

A delay in the humidiﬁer activation can be set, starting from the activation signal from the recovery unit previously described.

T CONTROL

This type of control consists of a Proportional+Integral type control of the temperature detected by a probe located in the return air, downstream from the exchanger. The proportional action will allow for the control of the ﬂow-rate as a function of the distance between the temperature detected and the setpoint. The integral action, on the other hand, will act on the reaction speed of the system.t. L’azione integrale, invece, agirà sulla velocità di reazione del sistema.

As seen in the ﬁgure, increasing factor P (dashed red line) reduces sensibility to temperature variations, resulting in a decreased reduction request in correspondence to the same temperature variation. The integral contribution, on the other hand, reduces the request to a greater extent the longer the deviation from the control temperature setpoint remains.

• controllo TH:

This type of control is used to modulate the capacity (water ﬂow-rate) with a temperature probe, installed in the return air, downstream from exchanger, an a limit humidity probe, usually installed downstream from the droplet separator. In order to enable this conﬁguration, a droplet separator is NECESSARY, otherwise there is a risk that the probe could get wet, thus constantly detecting humidity values close to the saturation point. The humidity probe will further limit the maximum request.

TT CONTROL

This type of control is used to modulate the capacity (water ﬂow-rate) with a temperature control probe and a temperature limit probe. The control probe is usually installed in the centre of the room and the limit probe in another “critical” point where the temperature must absolutely not be lower than a settable limit value.

TF CONTROL (T + air ﬂow/ﬂow-rate limit)

This type of control is used to modulate the capacity (water ﬂow-rate) with a temperature control probe and an air ﬂow modulator, which can correspond to:

• the modulating opening signal of the recirculation air lock;

• the modulating signal from the fan

In this case, the limit signal will function as:

• a temperature limit signal, in the event of a modulating signal from

the fan

• a humidity limit signal, in the event of a air lock opening modulating

signal.

PH/PT/PF CONTROL

The modulation of the capacity is proportional to an external control signal and limited based on the measured value of the temperature, humidity or ﬂow limit signal. This is the typical conﬁguration when the control is entrusted to a Building Management System that generates a control signal.

This control mode corresponds to the ON/OFF operation, from a nonpowered external contact (for example, a humidistat). The capacity will therefore be the maximum set or nothing (no modulation) according to the status of the external contact and limited based on the limit signal. See sections TT/TH/TF for more information regarding limit signals.

• C control

This control corresponds to the ON/OFF operation mode without any limit probe. The request directly follows only the control contact.

Note: Whenever the activation signal from the recovery unit is a digital signal, the control contact will NOT be the same signal; they will be two distinct signals.

8. SINGLE ZONE AND MULTIZONE CONFIGURATION

The humiFog system can be used in the following conﬁgurations:

8.1 Single zone

For humidiﬁcation and/or cooling applications in AHUs or industrial environments. The pumping unit has just one distribution system, a rack in the case of AHUs or a room distribution system with simple manifolds and nozzles or blower units. The humiFog control system (single zone version UAxxxxxxxx) controls both the pumping unit and the connected distribution system. In particular, it receives signals from the probes and/ or the external control system, calculates the required humidiﬁcation/ cooling capacity, starts the pump to pressurise the water and manages the solenoid valves in the distribution system. In addition, it manages the ﬁlling, wash and drain cycles.

Single zone application in AHU

As can be seen in the ﬁgure, humiFog is a complete system for humidiﬁcation/cooling in AHUs. humiFog can be set for:

- capacity/ﬂow-rate control: As described in detail in the paragraph “humiFog with ﬂow control”, the humiFog controller managers the humidiﬁcation and/or cooling capacity by controlling the water ﬂow-rate atomised continuously across a wide range of modulation. The outlet pressure is kept within the optimum water atomisation limits by the range of modulation of the pump speed and control of the number of nozzles that atomise the water. For example, if low capacity is required, only the ﬁrst group of nozzles is activated and the pump speed will be controlled to ensure the required capacity (Fig. 8.a point 1). If the request increases, the pump speed will increase and, as a consequence, the ﬂow-rate and outlet pressure will increase. If the pressure exceeds the maximum limit (75 bars, settable) humiFog will activate a further group of nozzles (max 4 groups), Fig. 8.a point 2, so that, for the same ﬂow-rate, the operating pressure will drop and fall within the limits (25-75 bars, settable). If the request increases further, the pump will increase the ﬂow-rate and the pressure until activating a further, third, group of nozzles (Fig. 8.a point 3). The process is repeated until the maximum ﬂow-rate is reached, corresponding to all the groups of nozzles being active and the pump operating at the maximum rack ﬂow-rate (Fig. 8.a point 4). Similarly, the system will behave in reverse if the request decreases, reducing the speed and consequently the ﬂow-rate of the pump and deactivating the groups of nozzles one after the other. The groups of nozzles on the rack are conﬁgured automatically during humiFog system selection procedure using the “humiFog excel tool” and is described in detail in the documents supplied with the water distribution system (rack). The ﬂow control conﬁguration guarantees maximum precision of humidiﬁcation and adiabatic cooling as capacity is controlled continuously and across a wide range.

- constant pressure control: As better described in the paragraph “humiFog with constant pressure”, humiFog is ﬁtted with an inverter to control the speed of the pump, so as to maintain the pressure at the rated value set by parameter, typically 70 bars.

Fig. 8.a

The water distribution system/systems have nozzles organised into groups, called steps, which in general each have diﬀerent capacities. Based on the ﬂow-rate of water to be atomised in one or more zones, the humiFog system will activate the best combinations of steps until the nozzles atomise the required quantity of water. For example, if the system has three steps with the following capacities: step 1 - 30kg/h, step 2 - 30kg/h; step 3 - 20kg/h, and the request is 30 kg/h, then step 1 is activated, if the request is 50 kg/h then step 1 and step 3 are activated, while if the request is 60 kg/h then step 1 and step 2 will be activated. In AHU applications, it is useful to suitably distribute the capacity of the steps so as to allow good resolution of capacity modulation. For example, a humiFog with a 180 kg/h rack, using 4 modulation steps and 4 kg/h nozzles, may have steps with the following capacities: step 1 96kg/h step 2 48kg/h step 3 24kg/h step 4 12kg/h Note that the resolution is 12/180=6.6%, therefore very good, with just 4 modulation steps! The technique involves assigning around half of the capacity to one step, half of this to the next step, half of the latter to the following step and so on, according to the following formula:

T-1

2N-1

With: S= capacity of step T M= rack capacity T= index of the step, 1 to N N= step number

N.B.: the maximum ﬂow-rate of one step is 120 l/h.

Obviously, the capacity calculated above should be rounded oﬀ based on the capacity of the nozzles (in this example, 4 kg/h), the number of nozzle manifolds that can be installed, etc. Each zone may have up to 6 modulation steps.

As can be seen in the ﬁgure, humiFog is a complete system for humidiﬁcation directly into rooms. As better described in the paragraph on “humiFog with constant pressure”, humiFog features an inverter to control the speed of the pump, so as to maintain the pressure at the rated value set by parameter, typically 70 bars.

The water distribution system/systems have nozzles organised into groups, called steps, which in general each have diﬀerent capacities. For simple installation and operation, however it is recommended to use steps of the same capacity. For example, a 100 kg/h system may have two 50 kg/h steps, where necessary made up of two or more lines with nozzles/blower units. Based on the ﬂow-rate of water to be atomised, the humiFog system will activate the steps required for the nozzles to atomise the necessary quantity of water. The zones can have up to 6 modulation steps. humiFog also manages rotation of the lines, emptying, washing etc, better described in the following paragraphs.

The groups of nozzles are normally conﬁgured when selecting and sizing the humiFog system.

8.2 Multizone application in AHU or room

For standard humidiﬁcation and/or cooling applications in AHUs or industrial environments. The humiFog controller manages the water pressure generated so as to keep it at a constant level, typically 70 bars. As illustrated in the following ﬁgure, the pumping unit has a distribution system, a rack in the case of AHUs or a room distribution system with simple manifolds and nozzles or blower units. The humiFog control system (multizone zone version UAxxxxxxxx) controls both the pumping unit and the connected distribution system. All the other zones, whether an AHU or an industrial environment, has a zone control cabinet ﬁtted with electronic controller that manages its own distribution system, a rack in the case of AHUs or a room distribution system with simple manifolds and nozzles or blower units. In addition, it communicates with the Master for all the common system procedures, such as washing, emptying, etc. Each cabinet, both Master and Slave, receives the signals from the probes and/or the external control system, calculates the required humidiﬁcation/cooling capacity and, when the water has reached the rated pressure, manages the solenoid valves in the distribution system to generate the required capacity.

Constant pressure control rationalises operation of the humiFog pumping unit as, despite the lower precision of stepped modulation, it can treat a number of zones at the same time without installing a pumping unit for each AHU or industrial environment.

For the conﬁguration of the steps, see the instructions provided in the previous paragraph “Single zone applications in AHUs – constant pressure control” and “Single zone applications in rooms”.

8.3 Indirect adiabatic cooling applications

One important function involves indirect adiabatic cooling applications (summer): a pumping unit can cool the exhaust air before it enters a heat recovery unit. This function is often complementary with the use of humiFog for air humidiﬁcation in winter. The conﬁguration in question is illustrated in the ﬁgure. The system can be conﬁgured in two ways:

• capacity/ﬂow-rate control: just one rack at a time atomises the water,

with continuous system capacity control and consequently maximum precision. See paragraph “4.1 Pumping unit with ﬂow control conﬁguration” for further information on capacity control.

• constant pressure control: two racks can atomise the water at

the same time or individually. This maximises energy saving by simultaneous indirect (cooling the air before the heat recovery unit) and direct adiabatic cooling (cooling the air before this is introduced into the environment), however with less precise control (stepped capacity modulation, see paragraph “4.2 Pumping unit with constant pressure control” for further information on capacity control).

For example, an indirect system with 100 kg/h of water sprayed can cool the exhaust air with an equivalent cooling capacity of 68 kW; this, in the heat exchanger/heat recovery unit, will cool the fresh air with an equivalent cooling capacity of 34 kW, for a power consumption of just

1.2 kW! In addition, this reduces the capacity required of the cooling coil and the chiller. For a detailed and complete description, see “Air humidiﬁcation” by Lazzarin - Nalini, chapter 11.

8.4 System operation

humiFog multizone independently manages the production of pressurised water, the distribution and ﬁlling, drain and wash cycles. This paragraph illustrates the latter functions.

Filling: before starting the production/atomisation phase, the piping must be ﬁlled with water and, then, vented of air. This ensures correct pressurisation of the lines and minimises the possibility of pressure swings due to air trapped in the piping. The system is empty when ﬁrst started and following draining due to extended inactivity (see the rest of the paragraph for further information). Before starting production, the system is ﬁlled by starting the pump, which generates the rated capacity of the pumping unit and ﬁlls the piping with water for a time set by parameter. This time must be established by trial and error when starting the system. When ﬁlling, all the capacity-control and drain valves in all the zones are open, while the vent and main drain valves are closed. The distribution system must be sized so that, in these conditions, the water pressure does not exceed 5 bars, thus avoiding situations where the nozzles atomise/spray water (each nozzle contains a valve that prevents atomisation at pressures below 7 bars).

Washing: this is performed periodically and involves ﬂushing water through the piping for a time set on the menu. The purpose is to completely wash the system and avoid stagnation of water. It is performed in the same way as ﬁlling, but lasts longer: the time should be set so that the water used for washing is at least 3 times the volume of water contained in the complete installation. The wash cycle is performed every day at the same time (e.g. every day at 4 in the morning) or periodically at an interval set by parameter. At the end of the ﬁrst wash cycle, the system remains full, while, starting from the second consecutive wash cycle without operation, the installation will be left empty. In addition, a wash cycle is also performed at start-up. If the wash cycle is disabled, then the system will be left empty after a period, set by parameter, during which it has remained full and without operation.

Pressure relief: this last function is used to save water and limit the ﬁlling and emptying cycles, without aﬀecting the hygiene features of the system, nor its performance. The pressure relief function, when a branch (piping with nozzles or blower units) is disabled (stops atomising), the capacity-control valve is obviously closed and the drain valve is opened. The latter, however, will be closed again a few seconds later so that the pressure falls below 7 bars (and then the nozzles no longer spray) however the branch remains almost completely full of water. This avoids emptying the branch (saving water) and having to ﬁll the system when production is required again in the branch. Note that opening the drain valve is required to achieve a rapid decrease in pressure from 70 bars to virtually 0, preventing the nozzles from spraying water at intermediate pressure values and generating large droplets that would wet the AHU/room.

Clearly, it is recommended to enable pressure relief. Indeed, thanks to the emptying procedure described above, in this case too there will not be stagnation of water in the piping for a time greater than the set value.

Rotation (only if “Pressure relief” is enabled): in constant pressure systems, humiFog periodically “rotates” the branches (piping with nozzles or blower units) that atomise the water. For example, if the zone has four branches and only two are in production, then the ﬁrst and the third will be activated, for example, for 20 seconds, and then deactivated; at the same time, branches two and four will be activated. After a further 20 s, branches two and four will be deactivated (with pressure relief), and one and three will be activated simultaneously. The example in the diagram with six branches gives a better idea: this shows an activation sequence where each conﬁguration (row) lasts 20 s. “A” indicates the active branch, “d” the inactive branch:

t=0

t=20s d

t=40s d d

t=60s

t=80s d

t=100s d d

Rotation is feasible if system operates with constant pressure and all the branches have the same rated capacity. Obviously, pressure relief must be enabled, otherwise each rotation would require a ﬁlling cycle.

8.5 Constant pressure systems: notes on capacity control

In constant pressure systems, humiFog keeps the pressure at the desired value when the required capacity changes (that is, the sum of the capacities required by each zone). Capacity required increases: whenever a zone requires an increase in capacity, the pumping unit does not respond immediately: the ﬂowrate/capacity of the pump is modiﬁed to generate the required capacity and only then is the signal sent to the zone, which suitably controls the solenoid valves (overboost cycle). For example, if a zone has 4 branches, 25 kg/h in each branch, two branches are active and the request increases to 75 kg/h, then the zone controller sends the request to the pumping unit, which increases the ﬂow-rate to 75 kg/h and, only when this has been reached, sends the signal to the zone to activate the third branch and consequently spray 75 kg/h. In the delay until the signal is received, the water pressure rises above the pressure set point, however this guarantees that, when the third branch is activated, the pressure will not fall below the required value and cause the nozzles to spray coarse droplets. During this transient period, the excess water is recirculated by the bypass valve. Subsequently, when the zone is in the ﬁnal status (solenoid valves suitably activated, third branch open, as in the example) the water pressure drops for a few seconds to around 60 bars, to ensure complete closing of the bypass solenoid valve (underboost cycle). Capacity required decreases: in this case, the pumping unit responds immediately to the request from any one of the zones to decrease the capacity. As a consequence of the reduction in atomised water in the zone/zones, the pressure will increase and the bypass valve may be activated. There will also be a reduction in the pump rotation speed (to reduce the ﬂow-rate to the new value required by the zone) and, if the bypass valve has been activated, an underboost cycle will be performed (see the description above).

In the general case where there are multiple zones that require variations in capacity, these will be satisﬁed one at a time, in order, and only at the end of the last variation will the underboost cycle be performed, if necessary.
