Working Principle of Air Source Heat Pump

An air-sourced heat pump operates based on the Reverse Carnot Cycle, extracting heat from the surrounding air to produce hot water.

The working principle of the system is as follows:

  1. It absorbs ambient heat and transfers it to the refrigerant, causing the refrigerant to vaporize.

  2. The refrigerant vapor then enters the compressor, where its temperature and pressure increase.

  3. The heated refrigerant passes through the condenser (heat exchanger), transferring heat to the hot water storage tank.

  4. The refrigerant flows through the expansion valve, reducing its pressure and temperature, and the cycle repeats.


As a leading air to water heat pump manufacturer, Calorstar proudly offers a range of high-quality air source heat pumps designed for every home.

Air source heat pumps are versatile and suitable for a wide variety of properties, making them a popular choice among homeowners. With their high efficiency and reliable performance, customers can count on consistent heating and hot water year-round.

Available in 230V to 400V options and multiple output capacities, our air source heat pumps are ideal for both residential and commercial applications.
