Sequence of Operation

SEQUENCE OF OPERATION

The dehumidifier’s ventilation system establishes the required airflow through the dehumidifier. The control system compares air temperature and humidity to their desired values (set points) and proceeds to dehumidify, cool or heat the recirculating air.

If the dehumidifier is equipped with the pool water heating option, the pool water temperature is compared to its set point and pool heating is provided if required.

Set Points

The control system is constantly adjusting unit operation to achieve and maintain said parameters within couple degrees/percent of the set point.

Refer to the dehumidifier’s main label for the design value of control parameters, as well as the following note.

NOTE

To ensure the dehumidifier’s most economical operation, we recommend maintaining

the following relationship between pool water and room air temperatures:

Room Air T = Pool Water T + 2˚F

Ventilation.

The main blower runs continuously, establishing required. The main blower speed is pre-set via adjustable variable signal.

Minimum Exhaust Fan (EF), if dehumidifier is equipped with such option, directs portion of return air outdoors. Like main blower, exhaust fan(s) speed is also controlled via adjustable (pre-set) variable signal, that varies based on scheduled ventilation mode (Occupied, Non-Occupied and Spectator) or call for Economiser Mode (as part of Air Conditioning and/or Dehumidification operation).

Minimum Outdoor Air (OA) damper, if dehumidifier is equipped with such option, opens to introduce fresh outdoor air into the premise. OA damper could be equipped with ON/OFF (simple fully open – fully closed) or modulating-controlled actuator; latter one would be controlled same way as minimum exhaust fan.

Purge (Additional Exhaust) Option.

Along with Min Exhaust Fan and Min Outdoor Air damper, dehumidifier could have additional set of exhaust (purge) fan(s) (PF) and purge outdoor air damper (POA), commonly referred as Purge. Purge

fan(s) and OA damper(s) function is to allow for higher exhaust and fresh air amount, up to complete (100%) air changeover (when all exhaust fans and OA dampers are at their max capacities).

Purge Fan(s) and Purge Outdoor Air damper(s) are controlled in the same fashion as min exhaust fans and min outdoor air. Some dehumidifiers may be equipped with additional Return Air damper: it closes in event of complete air changeover, separating return air side of dehumidifier from supply side (refer to Layout and Components chapter, as needed, for respective devices’ location).

Complete air changeover, triggered manually, is known as Purge Mode.

Externally installed Exhaust Fan(s) and Outdoor Air damper(s) could be also controlled by the

dehumidifier control system. This applies to both, Minimum and Purge/Additional, fans and dampers.

Dehumidifiers, packaged with Minimum Exhaust Fan and Minimum Outdoor Air damper, could also have additional

Heat Recovery (HR) closed-loop glycol system.

Heat Recovery loop consists of two coils (air-to-glycol heat exchangers) and a pump, establishing glycol

circulation between them. One coil, installed at exhaust air opening, recovers portion of exhausted air energy, another coil, installed at outdoor air intake, transfers this captured energy to entering outdoor air.

Figure 11. Heat Recovery Loop

Air Conditioning, Dehumidification and Pool Heating.

When premise air temperature goes over (exceeds) its set point, the dehumidifier control system issues a call for Air Conditioning Mode. Respectively, when premise air humidity goes over (exceeds) its set point, the dehumidifier control system issues a call for Dehumidification Mode. In some instances, these calls may co-exist.

To execute Dehumidification or Air Conditioning (Cooling) mode, control system, depending on current conditions, would resort to available means of cooling or dehumidification.

Economiser Mode Option.

NOTE

Economiser Mode requires dehumidifier to be equipped with full (min and additional) exhaust and outdoor air options!

If outdoor air is dry and/or cool, it could be used to dehumidify and/or cool the premise. In this case, on call for Dehumidification or Air Conditioning mode(s), control system would simply increase exhaust fan(s) speed signal to direct more stale return air outside and bring in more outdoor (dry/cool) air in, thus reducing supply air humidity and/or temperature (as needed).

Sequence of Operation

Compressor(s)

Whenever the compressor operates, the evaporator is always dehumidifying and cooling the return air. The heat removed from the air at the evaporator, as well as the heat from the compressor's action, must be rejected to one of three heat sinks: room (premise) air, pool water (if applicable) or outdoors. The control system will direct the heat to where it is needed based on room (air and pool water temperature) conditions:

• If room air is needed to be warmed up – more heat is diverted towards reheat coil;

• If pool water is needed to be warmed up – more heat is diverted towards pool heating coaxial heat exchanger

(if dehumidifier is equipped with this option).

• Rest of the heat (if any) is diverted towards outdoors (outdoor condenser, fluid cooler, etc.)

Compressor Circuit Operation

Piping schematic for compressor circuit is shown below.

When a demand requires the compressor to operate, the following sequence occurs:

• Once blower operation, related safeties and timers are confirmed by the control system, the pump down solenoid

valve opens and once pressure stabilizes, the compressor starts.

• Based on the premise air temperature, the refrigeration reheat and/or AC solenoid valve opens, allowing

refrigerant to flow through the respective condenser:

 if more heat is required by the room air, the reheat solenoid valve opens (heat is rejected to the premise);

if more cooling is required by the room air, the AC solenoid valve opens (heat is rejected outdoors (via outdoor condenser or plate heat exchanger).

 Outdoor condenser or fluid cooler fan is engaged only if hot gas is diverted outdoors and compressor

pressure is higher than pre-set level (see Outdoor Condenser and Fluid Cooler Operation below).

• Dehumidifiers, equipped with pool water heating option, also engage the refrigeration pool water heating

solenoid valve to reject heat into the pool water, based on pool water temperature.

Figure 12. Piping Schematic

Interface and Communication

• Once demand for the compressor’s operation is removed (respective call is satisfied), the pump down solenoid valve closes; once the compressor suction pressure reaches the pre-set pressure, the compressor stops.

Outdoor Air Condenser and Fluid Cooler Operation

Based on the type of the outdoor condenser or fluid cooler fans’ type (two-speed fans or EC-type/modulating fans), respective signal(s) are sent by control system to engage said fan(s): for two-speed fans - on/off signals (switching speeds, based on compressor head pressure level), for EC-type fans - variable 0-10VDC signal (proportional to the compressor head pressure level). Refer to the fans’ type and wiring diagram if/when needed.

If the fluid cooler is equipped with the built-in pump package (to establish cooling fluid flow between dehumidifier and the fluid cooler or to serve as additional/booster pump), the said pump is also engaged along with fluid cooler fans – pump would stay engaged while fans are engaged (regardless of the fans’ speed).

Space Heating

When premise air temperature drops below the set point, the dehumidifier control system issues a call for Space Heating Mode and engages space heater (electric heater, hot water coil with valve, gas boiler etc.) by sending space heating signal, respective to space heater control type - on/off, variable (0-10VDC), etc.

Gas Boiler Package, one of the available space heating options, is a closed-loop water/glycol heating circuit, that consists of a hot water coil, instantaneous gas boiler, pump and mixing 3-way valve. Boiler package piping general schematic is shown in Figure 13 (depending on required capacity, boiler package could be single or double (as shown on picture)):

• The pump is engaged and maintains constant water flow whenever space heating call exists. The mixing valve responds to the space heating call – the more heat is needed the hotter water is diverted towards the space heating coil. Boiler is controlled and operated via its own control system, responding to proper gas pressure, water flow, and will supply glycol at a constant temperature.

alarm-related stoppages and lock-outs. Continuous dehumidifier restarting (clearing alarms)

without addressing actual issues may result in equipment malfunction, premature wear, and failure.

For a complete list of alarms and alerts, refer to the Alarms Description information – contact PoolPak to obtain one.

Remote Communication (Virtual-Tech and BMS)

Although PoolPak dehumidifiers are designed to operate as a selfcontrolled device (not requiring any external control), communication between the dehumidifier and external control and monitoring systems is possible.

Virtual-Tech

Virtual-Tech is an online that allows for remote communication to the dehumidifier for various purposes such as monitoring, data collection, parameters adjustment, and notifications. This feature is included with all dehumidifiers and is useful for maintenance teams and service providers (HVACR technicians).

To establish Virtual-Tech communication, the dehumidifier must communicate with the PoolPak server via the Internet:

• Connect the dehumidifier to a local network switch, router or wireless AP device (providing connection to a local network):

 Plug an Ethernet cable into the sub-board Ethernet RJ-45 jack (sub-

board, called Core Module, is located on the main control board in the main electric panel) – see Figure 15.

• Configure, as needed, local server and dehumidifier network settings.

NOTE

Figure 15. Main Electric Panel

Separate R J-45 jack (plastic, black) is mounted on the control board directly, for TouchDisplay connection.

Make sure to use the proper jack (metal-surface one, located on the sub-board) for Virtual-Tech connection.

Interface and Communication

BMS (Building Management System)

Communication to BMS can also be supported, depending on the type of communication protocol said BMS utilizes.

The PoolPak equipment control software supports most common of them

• different control software variation might be required to support different BMS communication protocols. Contact PoolPak if necessary.

BACnet (Internet, IP). Communication is established via the Ethernet cable (same method as Virtual-Tech).

• BACnet and Virtual-Tech communication can be used simultaneously.

LON or Modbus. Communication requires external wiring between dehumidifier main control board and BMS terminal. Wiring schematic is normally indicated on wiring diagram (provided with dehumidifier).

• If dehumidifier is equipped with LON communication option, it’s normally provided with pre-wired LonWorks Gateway for communication purposes.

For more information about Virtual-Tech or BMS communication set up (connection, configuration, access, point cutsheets, etc.) – contact PoolPak.

Basic Maintenance

BASIC MAINTENANCE

Although PoolPak equipment is built for minimal service downtime, periodic preventative maintenance is required to ensure maximum reliability, safety, and operating efficiency.

! WARNING

To ensure equipment longevity and proper and efficient operation, the dehumidifier and its auxiliary systems and devices

(outdoor condenser, fluid cooler, boiler package, etc.) must be maintained properly and regularly. It is recommended to

create a facility-specific Routine Maintenance Program. Failure to maintain the equipment properly and regularly

could result in personal injury, equipment damage or malfunction and will void the equipment warranty.

Maintenance and Safety

Only qualified/properly trained personnel should attempt to perform respective maintenance tasks.

• When it is necessary to work with live electrical components, have a licensed electrician or other qualified professional perform the required task.

• Be properly trained and equipped. Some maintenance tasks may involve usage of power tools, chemicals, etc. Refer to such tools and materials data (manuals, MSDS, etc.). Personnel performing such maintenance tasks should be:

 Properly trained to handle such tools and materials safely

 Equipped with proper personal protective equipment

• Turn the power off. Before performing any maintenance, disconnect all electrical power, including remote disconnect, and discharge all energy storing devices (VFDs, etc.) before servicing. Follow proper lockout procedures to ensure that power cannot be accidentally restored. Failure to follow provided safety warnings and labels could result in serious injury or death.

• Be aware of potential hazards. The Equipment contains moving mechanical parts, components under high refrigerant pressures and surfaces with high temperatures. Before entering the dehumidifier and/or performing any equipment maintenance work, make sure that all moving parts are stopped, and it is safe to perform required task.

Maintenance Key Points

Here are some basic/key maintenance considerations, pertinent to all dehumidifiers and their auxiliary systems:

• Dehumidifier in mechanical room. No chemicals should be stored in the same mechanical room where the dehumidifier is installed. Chemical fumes/off-gas can cause premature deterioration of the equipment.

 Store chemicals in a separate, well-ventilated room.

• Access to the Equipment. Ensure that the equipment is accessible (minimum clearances are maintained): approaches to the dehumidifier are not restricted/limited with materials in mechanical room (indoor installed) or with snow (outdoor installed dehumidifiers, OACC and OAFC).

• “MUST DO” maintenance task. Although all other maintenance tasks are as important, these two maintenance tasks are the most common and most helpful:

 Maintain clean air filters (return, outdoor air filters, etc.). Make sure to replace dirty filters regularly.

 Maintain clean air-side coils (especially Outdoor Condenser or Fluid Cooler). Make sure to clean coils

re gularly.

• Pool Water Chemistry. Incorrect pool water chemistry (improper pH level or high concentration of chlorine, sea salt or other corrosive additives etc.) can result in equipment premature wear or malfunction (let alone poor air quality in the pool and potential health issues) and will void the equipment warranty. Refer to pool water quality standards; contact factory as needed.

Basic Maintenance

Routine Maintenance Program

Creating facility-specific routine maintenance program and following it is vital to equipment longevity and efficient operation.

The suggested general maintenance operations and their frequency/intervals, listed in the table M-1 below, can be used to create such a program. For more detailed maintenance recommendations related to specific components, refer to the respective component manufacturer’s manual.

Table 3. Recommended Maintenance Tasks and Intervals

Basic Maintenance

Specific Components Maintenance

Actual maintenance plan may vary from installation to installation, yet there are several key components from maintenance prospective.

If needed, contact respective component manufacturer for additional maintenance information.

Filters

• Ensure air filters are clean. Dirty air filters will negatively affect dehumidifier performance and lifetime

• Frequency of filters replacement will vary based on air quality, dehumidifier usage, facility type, etc. Make sure to replace filters regularly

• Replace with filters of equivalent size and rating – refer to dehumidifier details (compartment stickers, etc.)

Insulation

Inspect dehumidifier insulation, exposed to airstream for microbial growth (i.e., mold). If there is evidence of microbial growth on the interior insulation, the insulation should be removed and replaced prior to operating the dehumidifier.

Air-Side Coils

• Warning: Hazardous chemicals! Cleaning agents can be highly acidic or alkaline. Handle all chemicals

carefully and use appropriate personal protective equipment (PPE). Refer to the cleaning agent manufacturer's Materials Safety Data Sheet (MSDS) for safety and handling information. Failure to follow all safety instructions could result in serious injury or death.

• Warning: Hazardous pressures! Coils containing refrigerant under pressure must not be cleaned using a solution over 150°F. Failure to follow these safety precautions could result in coil bursting, which could result in serious injury or death.

To clean the coil

• Disconnect all electrical power to the equipment

• Use a soft brush to remove loose debris from the coil

• Mix a high-quality coil cleaning detergent with water according to the manufacturer's instructions

• Clean coil according to suggested instructions

• Thoroughly rinse both sides of the coil and the drain pan with, clean water

• Straighten any coil fins that have been bent during the cleaning process

• Confirm the drain line is clear

• Replace all panels and parts and restore electrical power to the equipment
