How a Heat Pump works
A heat pump draws heat energy from the surrounding air
and transfers that heat energy to the water of the swimming
pool. A heat pump works like a reverse cycle air conditioner,
using an evaporator, a compressor, and condenser to heat
water instead of cooling air.
The fan circulates air through the outer evaporator air coil
that acts as a heat collector and absorbs heat from the
ambient air. The liquid refrigerant in the air coil absorbs
the available heat in the air transforming it to a gas.
Step 2 Transfer
The compressor then receives the warmed refrigerant and
intensifies the heat. The intensely hot refrigerant is then
pumped into the heat exchanger (condenser).
Step 3 Heat Exchange
The heat from the hot refrigerant flowing inside the heat
exchanger is then transferred to the pool water, via the
surface of the heat exchanger's coils.
Step 4 The cycle begins again
The refrigerant is then ready to restart the process and flows
into the evaporator air coil to collect heat again.
