The heat pump sucks in the surrounding air with the use of a fan and circulates the air through the outer evaporator air coil that acts as a heat collector.
The refrigerant in the air coil absorbs heat from the air. The heat will be absorbed into a gas.
The refrigerant gas is then compressed by the compressor to become hot refrigerant, but still in gas form.
This hot gas is then pumped into the heat Exchange Condenser where the actual heat exchange takes place.
As the pool water passes through the Heat Exchanger, the hot gas transfers its heat to the pool water.
The Green Heat Pump can make 5 times more energy than it consumes.
So if the heat energy is converted to KW, then for every one KW of electricity consumed you get 4-5 KW of heating output.
You cen also get cooling output. The heat pump can be switched to the chilling mode. In this case the heat is transferred from water to the outside air.
