HDCP Series (High Dehumidification Control Package)

For large dehumidification requirements, E-Tech offers the HDCP series of commercial pool heater and dehumidifiers. HDCP packages incorporate two stages in series for superior humidity control in larger indoor pool facilities. They provide pool heating and substantial energy savings over conventional systems.

The HDCP system monitors the humidity conditions and uses stage one during normal conditions; then brings on the second stage only when high humidity conditions are encountered, stabilizing the humidity conditions.

How the HDCP System Works

The HDCP Pool heating Dehumidifying System recovers the energy lost by the pool to the atmosphere through evaporation. This produces cool, dehumidified air which is returned to the pool environment, stabilizing the humidity. The recovered energy is returned to the pool water to maintain the desired temperature. Excess energy is used to reheat the air that has been cooled in the dehumidifying process to help maintain the interior temperature of the pool enclosure. The HDCP system reduces the need for fresh air ventilation to control humidity and provides additional energy savings since less fresh air is required to be heated during winter operation. They are designed to keep relative humidity at a comfortable 55% to 60%.

Warm humid air from the pool room is drawn through the air filter and cooling coils to condense moisture from the air, providing maximum dehumidification. The heat from the compressor is used to heat pool water through the water heat exchanger. When the pool water temperature is satisfied, the heat is directed to the reheat coil where the dried air is warmed, if needed. A blower forces the dry air through the optional auxiliary heater and into the duct system to blow toward windows and skylights where condensation is most prevalent. If air conditioning is needed, each stage can be provided with an outdoor air cooled condenser. When all conditions are satisfied (water heating, dehumidification, space heating or air conditioning) the HDCP will turn off.

Typical applications

HDCP systems are typically used in larger indoor pool environments, or those with high humidity conditions. Common applications include therapeutic pools with warmer temperatures or high activity pools in schools, colleges and recreation centers.

Features and Advantages:

• The HDCP series two stage design provides great flexibility for the load condition of the pool enclosure. Both stages operate simultaneously at full conditions, but only one stage operates when inside humidity is satisfied for inactive or overnight conditions.
• The unit provides 100% heating of the pool water.
• The unit is provided with a PLC to control all functions and is compatible with all building automation systems and internet connections.
• Standard painted aluminum cabinets provide better corrosion resistance than painted steel.
• Panels are double skin insulated with 1'' fire resistant Fiberglass Thermostat insulation.
• Air coils and blowers are coated for additional corrosion protection.
• The HDCP uses environmentally friendly R-407C refrigerant.
• System monitoring (24 hours per day / 7 days per week) can be provided by AERS.

Optional Features:

HDCP systems can be customized for individual applications by including the following options:

Economizer Module

The economizer module allows the use of outside air for dehumidification when it is more economical. It is attached to the air inlet of the unit and includes a return air blower and connections to the exhaust and fresh air ducts. Each economizer is provided with three motorized dampers. The use of the Economizer is determined by a dew point controller in conjunction with the PLC which is provided in the basic unit. The economizer module is provided with a VFD blower which works from 100% fresh air to 20% fresh air.

Heat Recovery Module

The heat recovery module uses the same return blower as the economizer module but has the added ability to recover energy from the exhaust air to heat or cool the incoming fresh air. The module includes an air to air plate heat exchanger, and can typically recover over 50% of the sensible energy that would otherwise be exhausted to the outdoors. The controls for the heat recovery module are provided by the PLC supplied with the basic unit.

Remote A/C Ready

This option provides on demand cooling. The unit is provided with refrigerant connections for field piping to an outdoor air cooled condenser. The condenser must be ordered separately, or can be supplied by others.

Outdoor Air Cooled Condenser

The units are provided for the Air Cooling Mode with outdoor air cooled condensers which consists of an air condenser and a number of axial fans.

Built-In Water Cooled Condenser

The HDCP can be provided with one or two integrated water cooled condensers to provide on demand cooling when a cooling water or Geo loop is available for that purpose. Condenser water pumps are not included.

Custom Air Flow Options

Each HDCP can be supplied with customized air flow and can be designed to meet the external static pressure required by the application.

Auxiliary Heating

Each HDCP can be provided with an auxiliary heating air coil for use with hot water supplied by another source, or electric heaters can be added to the discharge ductwork of the installation.

Selecting the Proper E-Tech Pool Heating/Dehumidification System for your pool:

The HDCP system best suited to your needs is a function of: pool size, building size, location of pool, activity levels and the climate in your area. The proper size will depend heavily on the pool water temperature and air temperature desired - the higher the water and air temperatures, the larger the size of the unit required.) Selection of the right system is important to get the desired results. AERS can assist you with selecting a HDCP system, contact us for assistance.
