What Is A Pool Heat Pump?

Swimming pool heat pumps extract the heat stored in the ambient air and transfer it to water. It increases the water temperature to reach the desired level. Comparatively, it operates like a reverse refrigerator to pump the heat into the water and discharge the cooler air back into the ambient air.

A correctly sized swimming pool heat pump can ensure constant, comfortable swimming pool temperatures all year round. This robust energy-efficient technology could dramatically reduce your utility bills up to 80%.

The key point about the amazing heat pump efficiency is that unlike electric heating coils and gas heaters, a heat pump does not produce thermal energy but simply moves thermal energy from the surrounding air to a hot reservoir. Heat pumps have been proven to be the most efficient water heating technology available for the last 30 years consistently delivering 3-5 times the efficiency of conventional water heating technologies.

How Does A Pool Heat Pump Work?

  1. Unlike a traditional electric resistive heater, a heat pump doesn’t use electricity to heat the water directly, instead it uses electrical power to run a compressor to transfer the heat from the ambient air into the water through a reverse Carnot cycle, it applies the same principle as a refrigerator but in reverse.
  1. The low temperature and low-pressure refrigerant pass through the evaporator since the refrigerant R410A has a boiling point of -48.5°C. It can therefore still absorb the heat from the ambient air even in a cold environment and become the low pressure, low-temperature superheated vapor.
  1. The compressor then utilizes electricity to draw in refrigerant and discharge high temperature, high-pressure superheated vapor to the water heat exchanger (condenser) where the heat exchange is taking place and water is therefore heated.
  2. With the condenser, the expansion valve turns high pressure, sub-cooled liquid released from the compressor into the low pressure, low temperature saturated liquid. The refrigerant will perpetually circulate until the water reaches the set point.

Ari can be used to heat outdoor and indoor swimming pools and considerably extend the swimming season in an economical and environmentally-friendly manner.
