How It Works
The transfer is accomplished in 2 exchanges:
- Heat in the air to refrigerant
- Refrigerant heat to pool water
1. During the operation, air is drawn through the heat collector by the fan. The delicate aluminum fins abdorb heat from the air and transfer it to the liquid refrigerant passing through the copper coils within the fins.
2. As heat is absorbed, the liquid "boils" becoming gas. This is called "heat of evaporation".
3. The compressor draws in the warm gas and compresses it, elevating its temperature considerably.
4. The hot gas discharges from the compressor to the condenser coil inside the heat exchanger whereby heat is transferred to the pool water. The temperature of the water is increased as the heat in the gas is depleted.
The compressor and fan require only a fraction of electricity to operate, compared to the heat energy that is transfered from the air to the water.
5. As the gas cools, it changes to a liquid state and returns to the heat collector to absorb more heat, continuing the heating process.
