In all air conditioning systems, the principle of refrigeration is identical. It is well known, the cooling circuit of our refrigerators which has the feature of extracting energy from a "cold environment" (indoor) to be discharged into a "hot medium" (outside air). The operation of an air conditioner is based on the phase change of a refrigerant: evaporation takes place with heat absorption, its condensation with generation of heat. Any air conditioner thus includes:
- Exchanger evaporator (1) where the cooling of evaporation of the refrigerant is sent to the air.
- A compressor (2) compressing the gaseous fluid, increasing its pressure and temperature.
- A condenser exchanger (3) where the gas in condensing gives up its heat.
- A regulator (4) is carried out where the decrease in pressure of the liquid refrigerant before it evaporates in the heat exchanger.
In cooling mode: The evaporator cools the room air treated, the condenser gives up its heat or air outside or water network.
In heating mode: A four-way valve (5) to reverse the cycle, the condenser becomes évaporteur becomes evaporator and condenser. The condenser then heats the room air treated, the evaporator absorbs heat from outside air. If the power in heating mode is not enough, the electric résisances can be used to provide the necessary complement.
