Principle of heat pump-Carnot cycle principle

1.3 According to the basic principle of inverse Carnot cycle:

After the low-temperature and low-pressure refrigerant is throttled and depressurized by the expansion mechanism, it enters the air switch to evaporate and absorb heat, and absorbs a large amount of heat from the air Q2;

The refrigerant after evaporation and absorption enters the compressor in a gaseous form, and after being compressed, it becomes a high-temperature and high-pressure refrigerant(At this time, the heat contained in the refrigerant is divided into two parts: one part is the heat Q2 absorbed from the air, and the other part is the heat converted into the electric energy in the compressor when the refrigerant is compressed.)

The compressed high temperature and high pressure refrigerant enters the heat exchanger, and the heat (Q1+Q2) contained therein is released to the cold water in the heat exchanger. The cold water is heated to 60 ° C and directly enters the heat preservation tank for storage.The exothermic refrigerant enters the expansion mechanism in a liquid form and is throttled and depressurized.

Heat from cold water Q3 = heat absorbed by the refrigerant from the air Q2+ heat converted from the compressor's electrical energy Q1,Under standard conditions: Q2=3.6Q1, which consumes 1 part of electricity and gets 4.6 parts of heat.
