Abstract: During the operation of the compressor, part of the heat is lost through the casing through convection and conduction in the surrounding environment. This part of the heat can be used to defrost air-cooled refrigerators and heat pump evaporators; refrigerator food thaw; heat pump unit for enhanced heating, etc. When the refrigeration system is operating, a large amount of condensation heat is discharged into the environment, causing waste of energy, increasing the ambient temperature, and reusing the condensation heat can not only reduce environmental heat pollution, but also an energy-saving method that turns waste into treasure. The use of condensation heat mainly includes defrosting of air-cooled refrigerators and heat pump devices; heating of domestic water and production of hot water, etc. The waste heat utilization of refrigerators and heat pump systems is an energy technology research, and the energy-saving benefits can be effectively realized on the basis of rational use of energy.
