You may be wondering how AC works or working of air conditioner.?
In this article, I will explain to you step by step.
The basic principle of air conditioner is to extract heat from a room or from some space.
AC extracts heat with the help of an evaporator condenser and compressor.
MAIN COMPONENTS OF AIR CONDITIONER
- EXPANSION VALVE
WORKING OF AIR CONDITIONER
Ac has five main processes which are responsible for the functioning of the air conditioning system.
First hot air blows throw evaporator then the heat of room air is exchanged in refrigerant so the temperature of the refrigerant is increased and The refrigerant converts into vapour form.
The condenser is located on the indoor unit and there is a fan located in an indoor unit in which flows room air throw the evaporator then the cooling of the evaporator is exchanged so the air becomes cool.
Refrigerant goes into the compressor and the compressor compresses the refrigerant,
So the temperature of refrigerant increases more due to compression.
A compressor is responsible for the flow of refrigerant.
Two processes take place in compressor ->
A. SUCTION – When the piston moves from up to down (suction stroke),
Then the vacuum creates in the cylinder so the low pressor and low-temperature refrigerant enter the compressor by opening the suction valve.
B. COMPRESSION – When the piston moves from down to up(compression stroke),
Then the refrigerant is compressed so refrigerant discharges from the cylinder by opening the discharge valve.
The hot refrigerant now comes into the condenser (a coil of copper or aluminum) which is located in the outdoor unit.
High pressure and high-temperature refrigerant coming from the compressor enters in the condenser.
The temperature of the refrigerant in the condenser is very high as compared to the temperature of the surrounding,
so the condenser ejects its heat because heat always flows from high temperature to low temperature.
You might have seen a fan in the outdoor unit which is fixed in front of the condenser which ejects heat of condenser.
vapor refrigerant converters into a liquid at the end of the condenser.
Now the liquid refrigerant comes into the dryer in which moisture of refrigerant is absorbed.
There are many filters in the dryer which cleans the refrigerant and cleaned refrigerant moves further……
Liquid refrigerant coming from condenser enters into Dryer.
The dryer has two functions-
- Refrigerant filtration
- moisture-absorbing from the refrigerant
5. EXPANSION VALVE
The work of the expansion valve now comes into light.
The expansion valve expands the refrigerant so the temperature of the refrigerant goes down.
WOW! The refrigerant is now cooled.
Refrigerant moves further.
Clean and moisture-free refrigerant moves into the expansion valve.
The function of the expansion device is to lower down the pressure of the refrigerant.
A small hole is there in an expansion device for lowering down the pressure of the refrigerant.
when refrigerant moves into the hole a resistance is offered to the refrigerant so the pressure of refrigerant lowers down.
6. AGAIN EVAPORATION
Again the refrigerant goes into the evaporator.
when the hot air blows throw the evaporator then the heat of room air is exchanged and finally, the cooling effect comes.
That is it.
Now let’s look into the main components of the air conditioner.
The compressor in the air conditioning system is used to raise the pressure of the refrigerant that is coming from the evaporator coil so it creates a pressure difference between evaporator and condenser.
The evaporator is a coil made of either copper or aluminum which is located in the indoor unit.
Cool liquid refrigerant flows in the evaporator coil so the cooling of refrigerant is exchanged with the room air and cooling effect comes….
The condenser is another coil which is used in the air conditioning system.
the condenser coil is connected with the evaporator coil with the help of some pipes.
the condenser is located in the outdoor unit.
the heat gathered by the refrigerant from the room is ejected outside from condenser with the help of a fan.
4. EXPANSION VALVE
The expansion valve is used to decrease the pressure of the liquid refrigerant and it also cools down the liquid refrigerant further.
The expansion valve is located in the indoor unit.
This is the whole working of the air conditioner.

Ans.– I made a comprehensive list of best ac
click to check
Q: What happens if the refrigerant is low?
ans. if the refrigerant is low in ac then ac will take longer to cool the space(room).
