How Does An Air Conditioner Work?

 Have you ever wondered how your air conditioner brings in cold air to your home during the unbeatable summers? There is a science behind the working principle of air conditioners. Irrespective of the type of air conditioner that is used like the split AC, the window AC, cabinet floor standing or roof top AC the basic principle of all these are the same. Even in case of invert er ACs which are more advanced than the traditional ones the working principles remains similar. If you are using an air conditioner in your home it is a good idea to have a basic idea about its working patterns.

 All air conditioners without fail has a compressor inside which compresses or pump the refrigerant gas. It is the compression of the refrigerant gas that produces the heat. The compressed refrigerant is then pumped to the condensing coils which in turn dissipates the heat to the outside atmosphere. It is during this process that the refrigerant takes a liquid form. The liquid refrigerant is the pumped towards the expansion valve. The expansion valve has a temperature sensor connected to it which works in correlation with the thermostat settings. The expansion valve releases appropriate amount of refrigerant to the cooling coils where the liquid form gets converted to a gaseous form. Conversion of gaseous form to the liquid form happens because energy is absorbed from the surrounding. After this the air passes through the fins that is attached to the coils and gets cooled down. After this it is blown into the rooms.

 It must be noted here that the function of an air conditioner is quite similar to that of a refrigerator that is more commonly found in households. Unlike refrigerators air conditioners do not have an exterior body on which it relies for insulation. On the contrary the walls of the home act as insulators in case of air conditioners. Both the appliance takes advantage of a physical law that involves phase conversion whereby a liquid refrigerant gets converted to a gaseous form.

 The parts of an air conditioner that are integral in giving you a cool and comfortable temperature are the following:

• Evaporator: It receives the liquid refrigerant

• Condenser: It facilitates the heat transfer

• Expansion Valve: It regulates the refrigerant flow into the evaporator

• Compressor:
A pump that pressurizes the refrigerant

 
It is true that air conditioners are a source of comfort during the unbearable summer season but with it comes some harmful impact on the environment as well. First with the use of air conditioners we are certainly putting to use more energy and the amount we pay as electricity bills are also higher. Besides some of the air conditioners also used chlorofluorocarbons (CFCs) which have severe impact on the environment.


 However, in recent years the harmful coolant has been replaced with something which is more environment friendly. Last but not the least, if users can put to use air conditioners more judiciously the use of energy will be lesser and we can achieve a balance between utility and comfort at the same time.
