POOLPAK™ OPERATION
The PoolPak™ fan draws in warm, moist air from the pool enclosure. This air passes through the evaporator
(dehumidication) coil and gives up heat energy to the refrigerant which is in a cool, liquid state. This exchange of
energy causes the air temperature to fall below its dew point, resulting in moisture condensation on the evaporator coil.
The moisture formed falls into the unit’s condensate drain pan. After passing through the evaporator coil, the refrigerant
becomes a cool gas.
The refrigerant enters the unit’s compressor, where it is compressed into a hot gas. While in the compressor, the
refrigerant absorbs the energy used to operate the compressor. This hot gas refrigerant then travels either through an air
reheat coil, the pool water condenser or to an optional auxiliary air conditioning condenser, which may be either air or
water cooled. If air heating is called for, the air reheat coil is used. The hot refrigerant exchanges energy with the cooler,
dehumidied air coming from the evaporator coil. This causes the temperature of the air to rise for heating.
If pool water heating is required the hot gas ows into a pool water condenser, where it adds energy to the incoming pool
water. This heats the pool water while the refrigerant is condensed into a warm liquid. If space cooling is called for, the
refrigerant ows to the auxiliary air conditioning condenser bypassing the air reheat coil and pool water condenser and
allowing cool air from the evaporator coil to provide space cooling.
The SR series includes a return fan that allows for economizer operation and up to 100% outside air as shown in the SR
typical schematic, Figure 2-2.
The S series can include a factory mounted exhaust fan (SE), an exhaust and purge fan (SEP) or just an outside air
damper (S). A typical SEP series unit is shown in Figure 2-3. This series does not have a return fan so that the outside
air is limited to about 30% under normal operation.
