Air Conditioning Systems

Air conditioning systems are designed in such a way; So that they can properly regulate temperature, humidity, and air quality. The basic working principle of an air conditioning system consists of two units. It involves the circulation system of the refrigerant. Eg: evaporator and condenser system. Refrigerant cools the environment by absorbing heat from the indoor air and transferring it.  It is to the outdoor air in the condenser. At the same time, the cold temperature air from outside is transferred inside the room.

An air conditioning system consists of several components. It includes; Compressors, condensers, evaporators, expansion valves and many other components including refrigerants. The compressor compresses the refrigerant which helps to raise the temperature and pressure. The function of the condenser is to send the heat absorbed by the refrigerant outside the room and keep the room cool.

  • There are many types of air conditioning systems. For example;
  • Split-system air conditioners
  • Central air conditioner
  • Ductless mini-split air conditioners
