    Control System The dehumidifier control system is composed of sensors, spread throughout the dehumidifier, Main Control Board, Operator Panel and other electric components, located in the Main Electric Panel. Temperature Sensors (Pic. D.2): a) Temperature sensors (thermistors) are used to monitor various temperatures (air, water, compressor, etc.);...

  • Page 20: Outdoor Air Fluid Cooler Layout And Components

    Refrigerant Sensors are located within the compressor compartment; exact quantity and location may vary per dehumidifier, dependent on its size and configuration, but typically sensors would be located closer to the floor/bottom of the equipment– where higher concentration of leaked refrigerant is more likely. Indoor-installed dehumidifiers would also have additional damper installed at the compressor compartment (not shown on the drawings Pic.
  • Page 21 Cooling (AC) coils (31) (where heat from glycol mixture is rejected to the ambient air) is mounted onto metal • frame, upstream (before) the fans (32), that pulls the air through the coils to absorb the heat. Normally, fluid cooler would have multiple coils and fans. Cooler NG-V-12 (Fig.1), comprised of two coils, mounted on the angle to each other, and two fans, presents a single block.

  • Page 22: 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.

  • Page 23: Heat Recovery Option

    Heat Recovery Option. 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 (see Pic. E.1 below) consists of two coils (air-to-glycol heat exchangers) and a pump, establishing glycol circulation between them.

  • Page 24: Compressor(S)

    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 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). Pic.
  • Page 26  To ensure that all dehumidifier’s compartments are properly vented (in event of a leak), indoor-installed dehumidifiers are equipped with Emergency Venting: compressor compartment (typically the only compartment that is outside of main airstream and thus not ventilated) is equipped with emergency damper, that will open (triggered by RDS in event of a leak) to allow for compressor compartment to be properly vented as well.

    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. RDS Sensor (Equipment with A2L refrigerant) Refrigerant sensor, installed within the dehumidifier, does not require any specific maintenance. Used sensor has long-life expectancy and not required to be replaced on regular basis.
  • Page 35 Special Maintenance Tasks. Fluid Cooler Winterization. Normally fluid coolers are used in the systems, filled with glycol mixture to prevent the system and the fluid cooler from freezing and, potentially, rupturing, when exposed to temperatures below freezing point. When fluid cooler is used with media that, when exposed to low temperatures, could freeze (water or lower- percentage glycol mixture), one way to protect the equipment is to drain it (also known as “winterization”...
