To give you a trivia, air conditioning doesn’t only refer to cooling the air; it can also mean heating, ventilation or disinfection or any other forms of air condition modification. The air conditioner to cool the air uses the principle of refrigeration cycle. Refrigeration is the process of removing heat from a closed space to lower its temperature and maintain the low temperature. the same is true for air-conditioning.

The air conditioner is composed of air conditioning compressor, condenser, evaporator, fan, expansion valve, tube and refrigerant.
