1. INTRODUCTION AND MOUNTING

1.1 optiMist description

optiMist is an evaporative cooler and humidiﬁ er that atomises water in ﬁ ne droplets which then spontaneously evaporate, removing heat from the humidiﬁ ed and cooled air. optiMist uses a vane pump to pressurise the water, subsequently atomising it through special nozzles. The sophisticated control system combines the action of an inverter, which regulates the speed and consequently the ﬂ ow-rate of the pump, with two solenoid valves that activate only the necessary nozzles, allowing the system to always work at the ideal pressure to atomise the water, across a wide range of ﬂ ow-rates. The eﬀ ect of cooling the air is due to the spontaneous evaporation of the droplets of water: the change in state from liquid to vapour occurs by subtracting energy from the air that, as a consequence, is cooled. Each kilogram of water evaporated absorbs 0.69 kW of heat from the air. optiMist is a complete evaporative cooling and humidiﬁ cation system that can be used to treat the air in an AHU (air handling units) and to both humidify and to indirectly cool the renewal air, in order to increase the energy eﬃ ciency of the AHU.

1.2 Components of the system

optiMist is comprised of

• a pumping station that pressurizes the water (4-15 bar). It also contains

the electronic controller that completely manages the pumping station, controlling the temperature/humidity in each section. Since it is equipped with an inverter and pressure sensor, it manages to control the ﬂ ow of water produced at any moment, thus ensuring maximum precision and minimum energy and water consumption.

• distribution and atomisation system of pipes for transporting the

pressurised water, which contain the atomisation nozzles and drain valves;

• droplet separator;

• temperature and/or humidity probes or control through external

signal;

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

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

1.3 Conﬁ guration of the optiMist system

The optiMist system can be conﬁ gured to:

1. Control the air humidity, installing a pumping station and a distribution

system (with two-step modulation) in the AHU humidiﬁ cation section.

Fig. 1.a

2. Control indirect evaporative cooling (IEC) by installing a pumping

station and a distribution system (with two-step modulation) in the upstream section of the AHU heat recovery unit.

Fig. 1.b

3. Control both humidiﬁ cation and evaporative cooling with a pumping

system that will serve the two distribution systems, each with onestep modulation.

Fig. 1.c

The conﬁ guration for indirect evaporative cooling applications is of particular importance. Besides humidiﬁ cation of the air in the winter, optiMist can be used in the summer to cool the discharged air in the summer before it enters a heat recovery unit. This conﬁ guration is explained in the detail in the chapters below.

optiMist humidiﬁ ers are available for:

• ﬂ ow-rates: 50 l/h (EC005...), 100 l/h (EC010...) 200 l/h (EC020..), 400 l/h

(EC040..), 800 l/h (EC080..) and 1000 l/h (EC100..);

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

2.2 Type of supply water

optiMist can work with:

• demineralised water

• soft water

• tap water

Following the evaporation process, the minerals dissolved in the supply water will be partially transported by the air ﬂ ow as very ﬁ ne powder and part of them will be deposited on the surfaces of the separator and the ﬁ ns of the heat exchanger.

The type and amount of minerals contained in the supply water determine the frequency of regular maintenance operations needed to remove these deposits from inside the AHU.

The main components of the system supplied by Carel which are aﬀ ected by any incrustations and which require regular periodic inspection and maintenance are the nozzles and droplet separator.

In order to maintain system hygiene and to reduce system management costs, Carel recommends supplying optiMist with water that has been demineralised by reverse osmosis, as provided for in the principal norms such as UNI 8884. In particular, Norm UNI 8884 “Characteristics and treatment of water for cooling and humidiﬁ cation circuits” suggests that evaporative humidiﬁ ers be supplied with fresh water (as indicated in directive 98/83/EC) having the following characteristics:

• electrical conductivity <100 S/cm;

• total hardness <5 °fH (50 ppm CaCO3);

• 6.5<pH< 8.5;

• chloride content <20 mg/l;

• silica content <5 mg/l;

Note 1: If demineralised water is not available, softened water may be used. In this case, in order to limit the aggressiveness of softened water, a minimum hardness no less than 3°f should be ensured.

Note 2: Carel recommends using mains water only if it has a hardness of less than 16°f or a conductivity of less than 400S/cm. The use of mains water leads to ordinary maintenance operations (nozzle and droplet separator cleaning) whose frequency depends on the chemical composition of the water.

3.7 Modulating control signal

The control signal input connections depend on the activated control algorithm.

Cables up to 30 m: two-wire cables cross-section 0.5 mm2 (AWG20)

To control the section for direct humidiﬁ cation (DEC: Direct Evaporative Cooling), the signal can come from:

• modulating control with external controller

• modulating control with limit probe (temperature or humidity)

• modulating control with humidity probe

• modulating control with humidity probe and limit probe

(temperature or humidity

To control the section for indirect humidiﬁ cation (IEC: Indirect Evaporative Cooling), on the other hand, the signal can come from:

• modulating control with external signal

• modulating control with limit signal (temperature or humidity

probe or air ﬂ ow-rate/ﬂ ow limit signal)

• modulating control with temperature probe

• modulating control with temperature probe with limit signal

(temperature or humidity probe or air ﬂ ow-rate/ﬂ ow limit signal)

Tab. 3.c

To set the type of operation, control and signal: “installer menu > control type

(see chap. 9.11 Installer Menu).”

Note: The use of shielded cables is recommended. The cables must not be lodged near power cables at 230 V/208 V or near remote control switch wiring: this way, the risk of measurement error risks from electromagnetic interference can be avoided.

3.12 Backup cabinet signal

HBT

Fig. 3.aa

Backup function

The backup function allows the activation of a supporting cabinet in case of unexpected switch-oﬀ of the main cabinet.

Two types of backup management are available:

• HBT: control on the heartbeat of the main control

• BMS: control by supervisor

The HBT control allows the activation of the backup cabinet keeping controlled the heartbeat (digital output HBT) of the main Optimist. Wiring the digital contact HBT with the BKUP input of the backup cabin, the backup function check if the heartbeat is active (BKUP contact closed). If the signal dies (BKUP contact opened), the backup cabin starts working.

The BMS control check the status of the DIG 75 variable. If the variable is 1, the backup cabin is oﬀ ; if it switches to 0, the backup cabin starts working.

Note: The enabling of the backup function must be set only in the Optimist for backup, inside “Zone Menu  Special Function 2/3” in Installer menu

Rotation function

The rotation function allows the periodical activation of the two cabins.

In the main cabin:

• enable Rotation function,without enabling the backup;

• set the Rotation time value.

In the backup cabin the HBT control must be set.

To permit the rotation to work, the wiring of the HBT control must be done from the main cabin to the backup one and vice versa.

4. PUMPING UNITS

4.1 Pumping unit with ﬂ ow control conﬁ guration

optiMist controls the humidiﬁ cation and/or cooling capacity by continuously controlling the atomised water ﬂ ow-rate across a wide range of modulation.

This conﬁ guration is used in the following applications:

• humidiﬁ cation and/or evaporative cooling (direct) in an AHU;

• humidiﬁ cation and indirect evaporative cooling in an AHU equipped

with a heat recovery unit (a single atomisation system atomises the water).

optiMist is equipped with an inverter to continuously and precisely control the speed of the pump and, consequently, the ﬂ ow-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.

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

If the ﬂ ow-rate required for humidiﬁ cation or evaporative cooling is small then a few nozzles will be enough to atomise the water; if the request increases, the increase in ﬂ ow-rate will cause an increase in pressure that, if it exceeds 15 bar, will activate other atomising nozzles (from the second modulation step) with a subsequent decrease in the pressure, bringing it within the optimum range. Similarly, if the humidiﬁ cation request decreases, the ﬂ ow-rate and thus the pressure will decrease and, if the latter approaches 4 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 diﬀ erent capacities; when suitably activated, these guarantee continuous modulation of the ﬂ ow-rate across a wide range, nominally from 40 or 20 at 100% (40% for pump 50, 100 and 200 l/h, 20% for 400, 800, 1000 l/h) the maximum ﬂ ow-rate.

Questo è possibile perchè gli ugelli sono raggruppati in gruppi, ﬁ no a 2, di capacita diversa che, opportunamente attivati, sono in grado di garantire una modulazione continua della portata in un ampio range, nominalmente dal 40 o 20 al 100% (20% per pompe 50, 100 e 200 l/h, 40% per 400, 800, 1000 l/h) della portata massima.

The groups of nozzles are normally conﬁ gured when selecting the optiMist system, and the procedure is clearly described in the documents supplied with the water distribution system (rack). The continuous ﬂ ow control guarantees maximum humidiﬁ cation and evaporative cooling precision as capacity is controlled continuously and across a wide range.

with a diameter of 35mm.

3. The discharge solenoid valves must be connected to the lower horizontal

collection with a diameter of 35mm.

4. The rack must be tilted at least 1° towards the discharge valves.

5. The connection pipes between the rack and pumping station must be

without pockets that could cause water stagnation.

When the rack has a ﬂ ow-rate of about 75% less than the maximum ﬂ ow-rate of the pump, instead of discharge solenoid valves, mechanical discharge valves may be used, which do not require wiring; in this case water consumption and discharge and reﬁ lling times are slightly increased. The discharge solenoid valves and mechanical valves can be connected directly to the rack and to discharge inside the pipe or they can be moved outside the pipe using the appropriate extension kit (see example kit ACKT1F0500). In the event of solenoid valve installation directly on the rack, inside the pipe, the width of the rack increases by 10cm. The collectors are populated with atomising nozzles in brass in the appropriate number to achieve the ﬂ ow-rate reported in the related code digit. The corner brackets are equipped with holes for mounting in the pipe.

Please Note: IF THE optiMist IS USED AS A CHILLBOOSTER AND WITH THE SAME DISTRIBUTION SYSTEM, SET THE MAXIMUM PRESSURE CONTROL AT 10 BARS.

5.2 Droplet separator

The droplet separator catches the droplets of water that aren’t completely evaporated in the air, to prevent them from getting downstream objects wet. They are made up of standard size modules that are assembled on a support structure to cover the section of the AHU. The structure, which is entirely made from stainless steel, facilitates drainage of the water captured by the droplet separator. To facilitate maintenance of the individual modules, removal and replacement is done from the front, by removing the appropriate front frame. The modules are available with glass ﬁ bre or stainless steel ﬁ ltering material. They are available in 3 sizes in height and width of the modules, the combination of which leads to 9 standard modules.

5. DISTRIBUTION SYSTEM

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

Fig. 5.a Fig. 5.b

6. APPLICATIONS

ripresa

mandata

Fig. 6.a

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

• data center

• oﬃ ce buildings

• hotels and call centers

• printing and paper industries

• cleanrooms

• libraries and museums

• textiles industry

• food industry

• direct/indirect evaporative cooling

• timber industry

• other industrial applications.

The possibility of using an atomising rack for indirect evaporative cooling is especially interesting: the air to be discharged is cooled evaporativeally (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 ﬁ gure.

6.1 Main advantages of optiMist

The main advantages of optiMist are:

• Highly reduced electrical consumption: about 1 Watt for every litre/

hour of humidiﬁ cation capacity;

• Maximum capacity: 1000 kg/h;

• Loading solenoid valves for the distribution system inside the cabinet;

• Excellent humidiﬁ cation and cooling eﬀ ect in the AHU due to the rack

being customised based on the AHU section;

• Very low maintenance required.

• Washing and draining cycles;

• Absence of dripping

• Silent nozzles

• Connectivity: optiMist can be connected to external systems such as

BMS using the ModBus protocols, ...

• Back up and rotation between two cabinets.

lgorithms, which can be selected from the installer menu.

• HH control:

modulates the capacity (water ﬂ ow-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 ﬂ ow-rate) with two probes, one humidity control probe and one limit temperature probe. This conﬁ guration 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;

• P control:

• 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 optiMist 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 ﬂ ow-rate and operating, temperature and humidity conditions, may change over time and, consequently an additional safety system is required to prevent the humidiﬁ er from over-humidifying the air and, in the worse case scenario, condensing in the ducts downstream.

Below are the two diagrams of operation with humidity or temperature probes

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 humidiﬁ er 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 humidiﬁ er 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 humidiﬁ er 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 ﬂ ow-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.

Fig. 7.d

As seen in the ﬁ gure, 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 ﬂ ow-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 conﬁ guration, 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 ﬂ ow-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 ﬂ ow/ﬂ ow-rate limit)

This type of control is used to modulate the capacity (water ﬂ ow-rate) with a temperature control probe and an air ﬂ ow 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 ﬂ ow limit signal. This is the typical conﬁ guration when the control is entrusted to a Building Management System that generates a control signal.

• P Control

This control is like the PH control, but without humidity limit probe. The following is a graphic with proportional control.

CH/CT/CF CONTROL

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.

7.3 Humidiﬁ cation + Evaporative Cooling

The optiMist humidiﬁ er provides the ability to conﬁ gure the outlet humidity control and the indirect evaporative cooling contribution control at the same time.

ATTENTION: the operation of the two zones is mutually exclusive;

the two zones, therefore, will never work at the same time.

Selecting the active zone will depend upon: a) the priority assigned by digital input ID4 (closed contact for I.E.C., open contact for Humidiﬁ cation) [see section 3.x]; b) the current request for humidity/cooling.

Once the priority is selected, the system will evaluate if the priority zone will be in request, otherwise it will satisfy the request from the other zone.

The following examples shows the case where the priority is set for indirect evaporative cooling, with step 1 dedicated to humidiﬁ cation and step 2 to indirect cooling.

8.4 Wizard

At machine start-up, once the language is selected, a guided procedure (Wizard) is accessed which allows the installer to conﬁ gure the principle machine operations.

The following lists the parameters that can be conﬁ gured using this procedure:

• Unit of measure.

• Number of steps and respective nominal ﬂ ow-rates

• Type of installation (only Humidiﬁ cation, only Evaporative Cooling,

• Conﬁ guration of the control inputs (with indications for verifying the

ﬁ tness of the electrical connections).

Once this procedure is correctly completed, the machine will be ready to operate.

Access to the Wizard section will then be possible through the Installer Menu - Wizard, or when the machine is restarted (if the option “Show Wizard at start-up” has not been disabled).

(*) The display shows a table where the columns represent the 2 capacity

modulation steps and the rows contain the following information:

Row F - the symbol “” is displayed if the branch is atomising, otherwise “-” is shown Row D - the symbol “” appears if the branch is draining (valve open), otherwise “-” is displayed if the drain valve is closed. In column Hr, if the heat recovery is active, the symbol “ “, otherwise “ “. In column Pr, the priority choice will be shown: the symbol “ “ if priority is given to Humidiﬁ cation, “ “ if given to evaporative cooling.

For example, the table may be as follows:

12L

F--Hr

D---

This indicates that branch 2 is active, heat recovery is active and priority is given to evaporative cooling. Another example may be as follows:

12L

F--- Hr



This indicates that no branch is active, the drain valve for branch 1 is open, the heat recovery unity is oﬀ and priority is given to humidiﬁ cation.

11. STARTUP

11.1 Startup

!Attention: before proceeding, make sure the unit is not connected to the mains.

Once the distribution system is assembled and the pumping station is installed, perform the operations listed below:

• Connection characteristics for connecting the water line to the

optiMist water inlet: G3/4”f;

• Connect a drainpipe to the discharge solenoid valve at the pipe

coupling, G3/4”f

• Connect the connection pipe(s) between the cabinet, G1/2”f and the

distribution system G1/2”f

• of the pressurized water outlet of the pump towards the lower oriﬁ ce

• connect the control signals and check that the control settings are

compatible;

• Connect the discharge solenoid valve to the related clamps;

• Connect the electric supply cable to the appropriate clamps L, N, PE;9.

• Open the manual water valve upstream of the cabinet;

• Set the knife switch to position “1”;

• At this point, voltage can be added using the external power switch;

• Activate the system using the control contact (Ref. par. 3.2);

• Check for any water leaks in the water circuit.

12. MAINTENANCE AND REPLACEMENT PARTS

12.1 Maintenance procedures

Since the optiMist humidiﬁ cation system does not require special maintenance in general, it is best to regularly perform systematic preventative maintenance. The interval depends on the water quality: the more salts or impurities in the water, the more frequently the inspections must be performed.

Components to check inside the cabinet:

• Check the water inlet manometer pressure value

• Check and clean the water ﬁ lter inside the cabinet.

• Check the water tightness of the corrugated stainless steel pipes inside

the cabinet.

• Pump: check for leaks or drips

Water lines:

• Check the tightness of the seals on the connection pipes between the

Cabinet and Rack.

Distribution system:

• Check the condition of the nozzles; clean or replace if necessary.

• Check the tightness of the connections whether threaded or

compression

Droplet separator:

• Check for clogging in the separator
