RV 220v Portable Air Conditioner

Refrigeration process

The compressor compresses the refrigerant into high-pressure gas, causing its temperature to rise.

The high-pressure gas dissipates heat through the condenser, cools and condenses into liquid refrigerant.

The liquid refrigerant enters the evaporator through the expansion valve, evaporates inside the evaporator, and absorbs heat from the air.
The evaporated low-temperature and low-pressure gas is sucked into the compressor again and circulates for the refrigeration process.

Heating process (some models)

Some RV base-mounted air conditioners have a heating function, providing heat through an electric heater or other means to keep the interior warm.

Fan and air circulation

The fan draws indoor air into the air conditioning system, and after being cooled by the evaporator, it is distributed to various areas in the RV through the air ducts.

At the same time, the hot air is cooled and discharged from the outside of the RV to maintain the circulation and circulation of indoor air.
