How Do Heat Pumps Work?

How Do Heat Pumps Work?

1. Temperature drops to -20℃ after the pressure release. When ultra-low temperature liquor cryogen enters and flows in absorbing heat evaporator, it meets air about 20℃;

2.Cryogen of 20 enters low temperature compressor, gets preasurized, heated up and turns into high pressure 80℃ gas.

3. Vaporized cryogen temperature of 80℃ passes heat to low cold water in heat exchanger, changing into 60℃ life used heat water which is pumped into warm keeping tank for storage throuth circulating pump. High temperature cryogen heat releases and turns into high pressure liquor.

4. High pressure liquor cryogen throttles and lowers pressure through expansion valve,entering into evaporator to absorb heat;

5. According to Reserve Carnot Circle Theory, compressor constantly repeatedly circles. The whole course is to transfer heat. As long as it use a kilowatt-hour electricity to drive compressor to work, it can absorb heat in the air equaling to that produced by 3-6kh electricity. Obviously it saves energy and works safely.
