An air conditioner works for the conservation of desired temperature in the enclosed room or area. The cooling effect of the air conditioner is based on round about mechanism of air. The air duct of the system draws the air from the room as well as blows out the clean wind that has the temperature level up to the required amount.

The air conditioning compressors are the main unit for evolving out the cool air. The air conditioners works on the same principle like a refrigerant. It has a compressor, condenser, evaporator and other smaller units that together work for the purpose. Besides cooling, these units carry the control of humidification in the room.

These conditioners generally use some chemicals that readily retort from gas to liquid and again, back to gas. The chemicals transfer the heat from air inside the room to outside. As mentioned earlier, an air conditioner has usually 3 main parts- compressor, condenser and the evaporator. Both the compressor as well as the condenser are situated on the outer side of the air conditioner. The evaporator remains inside and sometimes as a part of the furnace.

The fluid or the chemical comes to the compressor as a cool, low pressured gas. Here it is squeezed and the molecules of the fluid come closer and its energy rises along with the temperature. From here, the hot gas flows to the condenser from where the heat dissipates away. Now, the gas has turned to liquid again and the cool liquid moves to the evaporator with high pressure through a tiny hole. Slowly, the pressure drops and it again turns into gas. While the liquid turns into gas, it draws the heat from the surroundings and thus the room air slowly becomes cool.

Thus, the air conditioning compressors are the main unit to start the mechanism of air conditioning.
