What is the working principle of air conditioning?
In simple terms, is the indoor quantity of heat, through the refrigerant to outdoor putting off Detailed process of refrigerant in the evaporator (indoor machine) evaporation heat, namely will indoor heat absorbed (refrigerant why will evaporate, because its boiling point, like liquefied petroleum gas, liquid in the flask, leaking out to turn into a gas) Absorb the heat, and then to the compressor, through compressed into high temperature and high pressure gas, then to the condenser condensing (outdoor), condensation is the process of heat release, and then liquefaction, under certain pressure, otherwise not liquefaction After liquefaction, refrigerant in capillary pressure, and then to the evaporator (indoor machine) evaporation heat, so the cycle, became a refrigeration system Summary, evaporation heat, condensation heat, evaporation heat, condensation heat... The cycle
The general is using refrigerant refrigeration and air conditioning. Is first of all, the gaseous refrigerant compressor compression for liquid, in the process, the refrigerant is compressed into a liquid, the coolant temperature rises, the temperature of the purpose is to improve the temperature difference between refrigerant and the environment, and then coolant temperature higher than the environment temperature and the heat release from the outside environment, the temperature drop to normal temperature, the pressure of the gas in the process of heat transfer that is constant, and then let the normal temperature of the liquid refrigerant entering the indoor evaporator, let cool liquid refrigerant expansion, make the temperature lower than indoor temperature so that the indoor air to the refrigerant exothermic, refrigerant heat recovery to normal temperature gas entering the compressor compressed again, continuous refrigeration cycle.
