The cooling system of split-system conditioners is also based on steam compression, where the compressor is the element responsible for pumping the refrigerant, the condenser is responsible for its condensation, by promoting the heat exchange between this fluid and the air. In the external environment, the expansion device controls the amount of refrigerant that enters the evaporator, causing the condensation pressure to fall to the evaporation pressure and the evaporator is responsible for the heat exchange between the refrigerant and the internal environment. .
The refrigerant is suctioned by the compressor through the suction line under low pressure and temperature (Example: for R22 evaporation temperature 6 ° C the pressure would be 73 psig), being
compressed, thus causing the temperature to rise (to about 90 ° C), this gas in the gaseous phase flows to the condenser through the discharge line which is exposed to the medium
long
If there is a temperature difference between the discharged vapor and the air from the outside environment, the heat is released by the refrigerant, which means that the fluid begins to release heat, consequently its temperature will decrease until the condensing temperature is reached. (about 10 to 15 ° C above ambient outside temperature). The fluid condenses by the release of latent condensing heat at constant temperature and pressure and flows into the expansion device.
