What is Air Condition and how does it work ?

That might also explain why it consumes so much electricity. In reality, however, that’s a misconception.

An air conditioner is not a magical device; it just uses some physical and chemical phenomena very effectively to cool a given space.

This warm air is drawn in through a grille at the base of the indoor unit, which then flows over some pipes through which the refrigerant (i.e., a coolant fluid) is flowing.

The refrigerant liquid absorbs the heat and becomes a hot gas itself.

This is how heat is removed from the air that falls on the evaporator coils.

Note that the evaporator coil not only absorbs heat, but also wrings out moisture from the incoming air, which helps to dehumidify the room.

This hot refrigerant gas is then passed on to the compressor (located on the outside unit).

Being true to its name, the compressor compresses the gas so that it becomes hot, since compressing a gas increases its temperature.

This hot, high-pressure gas then travels to the third component – the condenser. Again, the condenser remains true to its name, and condenses the hot gas so that it becomes a liquid.

The refrigerant reaches the condenser as a hot gas, but quickly becomes a cooler liquid because the heat of the ‘hot gas’ is dissipated to the surroundings through metal fins.

So, as the refrigerant leaves the condenser, it loses its heat and becomes a cooler liquid.

This flows through an expansion valve – a tiny hole in the system’s copper tubing – which controls the flow of cool liquid refrigerant into the evaporator, so the refrigerant arrives at the point where its journey started.

Although all the components involved in the air-conditioning process in window ACs are located inside the same metal box, the underlying process of cooling remains exactly the same.

The entire process is repeated over and over again until the desired temperature is attained. In a nutshell, an AC unit keeps drawing in warm air and expelling it back into the room until there’s no more warm air left to cool.

Dependent as we may be on air conditioners, it’s surprising to note that they were not intended for human comfort when they were initially developed.

The motivation for the first modern air-conditioning system was to eliminate certain problems in the manufacturing processes of a publishing company!

To think that a machine intended to support publishing papers on a large scale could one day become an integral part of every modern household is quite something, isn’t it?

You know your air conditioning system keeps your home or business cool in the hot summer months, but have you ever wondered how it works?

One interesting fact you might not know is that your air conditioner and your refrigerator work primarily the same way.

The difference is your refrigerator cools a small, insulated space, and an air conditioner keeps your home, office, or commercial space at a comfortable temperature.

The entire process of making the air in your property a comfortable temperature is based on a very simple scientific principle, and the rest is achieved by mechanical means. Let’s take a look at how air conditioning works to cool your home.

Your air conditioning unit uses chemicals that convert from gas to liquid and back again quickly.

These chemicals transfer the heat from the air inside your property to the outside air.

The AC unit has three key parts. These are the compressor, the condenser, and the evaporator.

Your unit’s compressor and condenser are typically located in the outside part of the air conditioning system. Inside the house is where you will find the evaporator.
