The working principle of air source heat pumps is based on the reverse Carnot cycle, which involves the compression system to absorb heat from the air to produce hot water. The specific process is as follows:
Low-pressure gaseous refrigerant enters the compressor, where it is compressed into a high-temperature, high-pressure gas.
The high-boiling-point refrigerant enters the condenser and begins to liquefy, releasing heat in the process and becoming a liquid.
Before entering the evaporator, the refrigerant passes through an expansion valve (throttle valve), which reduces the pressure of the refrigerant.
The pressure-reduced refrigerant starts to evaporate in the evaporator, absorbing heat in the process and becoming a low-pressure gas again.
It then re-enters the compressor, and the entire refrigerant cycle system is formed in this way.
