10HP Low Ambient Temperature Heat Pump

What’s the working principle of low ambient temperature air source heat pump?

The heat pump unit is a closed system composed of evaporator, condenser, compressor and expansion valve, which is filled with an appropriate amount of refrigerant.

The basic principle of heat pump operation is based on the principle of reverse Carnot cycle: the liquid refrigerant first absorbs the heat in the air in the evaporator and evaporates to form steam (vaporization), and the vaporization latent heat is the recovered heat. Then it is compressed into high-temperature and high-pressure gas by the compressor and enters the condenser to condense into liquid (liquefaction) to send the absorbed heat to the required heated pool water, The liquid refrigerant returns to the expansion valve after depressurization and expansion through the expansion valve, absorbs heat and evaporates to complete a cycle. In this way, it continuously absorbs the heat of the low-temperature source and outputs the heated swimming pool water to directly reach the predetermined temperature.
