independent of the need for dehumidification. In this compressor mode, the heat removed from the space air by
the evaporator will be directed to the auxiliary condenser. For MSE and MSEP units, the air is exhausted before the
evaporator. By exhausting the warm air before the evaporator, the highest enthalpy air is removed from the system
which reduces the load on the air cooled condenser.
AIR CONDITIONING WITH AIR-COOLED CONDENSER
The PoolPak can be equipped with a properly sized integral or remote air-cooled condenser. The remote condenser
can also be installed on a separate pad.
AIR CONDITIONING WITH WATER-COOLED CONDENSER
The PoolPak can be equipped with a remote-mounted water-cooled condenser. This condenser can be either
cleanable or non-cleanable. Sensible and latent heat recovered in the air conditioning mode is rejected to the water
condenser if pool water temperature requirements are satisfied.
AIR CONDITIONING WITH CHILLED WATER COIL
When chilled water is available, a chilled water coil can be factory-installed upstream of the supply fan. The coil
has a factory-installed and wired three-way flow control valve and is controlled by the PoolPak control system.
Pool Water Heating
If the space temperature is at or above the set point and the pool water temperature is below the set point, hot gas
is directed to the pool water condenser when the compressor is running. During times when the pool water requires
more heat than is available from the pool water condenser, the PoolPak® activates the auxiliary pool water heater.
An auxiliary pool water heater must be supplied as part of the pool water pump and filter system.
Smart Pump Control (Optional)
Smart Pump Control allows the CPCS to control operation of a field-installed booster pump to the PoolPak pool
water condenser. When the CPCS determines that pool heating and space cooling are required, a contact
closure signal activates the remote pump. The pump will be deactivated when the pool heating and space cooling
requirement is satisfied. This control sequence requires separate field mounting of a factory supplied pool water
temperature sensor where continuous pool water flow is expected.
Networking Multiple Units
CPCS networking allows multiple units to be connected together. The units will work with each other to control water
temperature, air temperature and relative humidity. Networked units have all the features of standard units plus the
ability to control water temperature in multiple pools. All units on the network are accessible from a single remote
interface unit for convenience.
Occupied/Unoccupied Control Mode
The PoolPak unit time clock allows 7-day, 24-hour scheduling of operational control for both occupied and
unoccupied times during the year. During unoccupied times, the outside air damper and exhaust fans are kept in the
closed/off position. This strategy minimizes the air-heating and/or air-cooling load during unoccupied periods. Also
during unoccupied mode, the supply fan speed is reduced by 20% (Night Fan Setback) further reducing fan energy
costs. During occupied times, the PoolPak operates to maintain outside air at programmed natatorium parameters.
