Many people think that buying an air source heat pump is so expensive. The working principle of an air source heat pump should be similar to that of an air conditioner. Anyway, they are both used for heating. Buy an air source heat pump? It’s better to buy an air conditioner!
So what is the difference between the working principles of an air source heat pump and an air conditioner?
The working principle of an air source heat pump
The electric drive compressor works to compress the low-temperature refrigerant into a high-temperature refrigerant. The high-temperature refrigerant exchanges heat with water through a hot water heat exchanger. After the heat exchange, the high-temperature refrigerant is depressurized by the expansion valve and then absorbs heat from the air through the evaporator. The refrigerant after heat absorption is sucked into the compressor, continuously absorbing heat from the air, and releasing heat on the hot water heat exchanger side to heat the cold water. The heat absorbed by the water is the sum of the heat generated by the compressor compression and the heat absorbed by the refrigerant from the air. Floor heating can also be added at the end of the air source heat pump.
Working principle of air conditioner
Electricity drives the compressor to work, compressing the low-temperature refrigerant into high-temperature refrigerant. The high-temperature refrigerant dissipates heat through the evaporator, and the air conditioner main unit fan discharges the heat to the outside. After the heat is dissipated, the high-temperature refrigerant is reduced in pressure by the expansion valve and then passes through the air conditioner indoor unit evaporator to absorb the heat in the air, lowering the indoor temperature. The refrigerant after absorbing heat is sucked into the compressor. In this way, heat is continuously discharged from the indoor air to the outdoor air, and heat is absorbed from the indoor air to achieve the purpose of lowering the indoor temperature.
