How to heat hotel air conditioners

The principle of air conditioning and heating:

When the air conditioner is heating, the gas Freon is pressurized by the compressor, becomes a high temperature and high pressure gas, and enters the heat exchanger of the indoor unit (in this case, it is condensation device), condensation, liquefaction and heat release, becoming a liquid, and at the same time heating the indoor air, thereby achieving the purpose of increasing the indoor temperature.

The liquid Freon is decompressed by the throttling device and enters the heat exchanger of the outdoor unit (at this time, the evaporator). It evaporates, absorbs heat, becomes gas, and absorbs the heat of the outdoor air (the outdoor air becomes colder). The Freon that becomes gas enters the compressor again to start the next cycle.

Principles of air conditioning and refrigeration

1. The solution is heated and boiled by the heat source in the generator, and the refrigerant vapor is generated and condensed in the condenser. Refrigerant liquid. The liquid refrigerant enters the evaporator after being throttled by the U-shaped tube. The evaporator is sprayed under low pressure conditions, the liquid refrigerant evaporates, absorbs the heat of the refrigerant, and produces a refrigeration effect.

2. The concentrated solution flowing out of the generator flows into the absorber after being cooled and pressure-reduced by the heat exchanger, and is mixed with the original solution of the absorber to become a concentrated solution of intermediate concentration. The intermediate concentration solution is transported and sprayed by the absorber pump, absorbing the refrigerant vapor coming out of the evaporator and turning it into a dilute solution.

3. The dilute solution is sent to the generator by the generator pump, and is regenerated by the heat source to generate refrigerant vapor to form a concentrated solution again, entering the next cycle.
