Waste heat refrigeration can help people to recover waste heat, energy consumption is saved, and cost is reduced.

Conventional compression refrigeration is a conversion process of electrical energy. The compressor sucks the low-pressure and low-temperature refrigerant gas (such as Freon) generated in the evaporator into the cylinder, and compresses the refrigerant gas into gas with higher pressure and temperature, and the gas is discharged into the condenser. Condensing into liquid, throttling and reducing pressure by a pressure regulating valve, and then entering the evaporator, wherein the low-pressure refrigerant gas is vaporized to absorb heat in the evaporator to reduce the temperature. This is the chilled water of the air conditioner that we need. The compression process requires a large consumption of electrical energy.
