You may be wondering that how Ac works? 

 

In this article i will explain you step by step.

Basic principal of air conditioner is to extract heat from room or from some space.
Ac extracts heat with the help of evaporator condensor and compressor.

MAIN COMPONENTS OF AIR CONDITIONER

  1. COMPRESSOR
  2. CONDENSER
  3. EVAPOARTOR
  4. EXPANSION VALVE
  5. REFRIGERANT 

WORKING OF AIR CONDITIONER

Ac has five main processes  which are responsible for the functioning of air conditioning system.

1. EVAPORATION

2.COMPRESSION

3.CONDENSING

4. EXPANSION

1. EVAPORATION

First hot air blows throw evaporater then heat of room air is exchanged in refrigrent so the temprature of refrigrent is increased and the refrigrent convertes into vapour form. working of air conditioner
condenser is located on the indoor unit and there is a fan located in indoor unit which flow room air throw the evaporator then the cooling of evaporator is exchanged so the air becomes cool.

2. COMPRESSION

Refrigerant goes into the compressor and compressor compresses the refrigerant so the temperature of refrigerant increases more due to compression.
compressor is responsible for the flow of refrigerant.

Two processes takes place in compressor -> A. SUCTION – When piston moves from up to down (suction stroke) then vaccum creates in the cylinder so the low pressor and low temprature refrigrent enter in the compressor by opening the suction valve. B. COMPRESSION -When piston moves from down to up(compression stroke) then the refrigrent is compressed so refrigrent discharges from the cylinder by opening dicharge valve.

3.CONDENSING

Hot refrigrent now comes into  condenser (a coil of coper or aluminium) which is located in outdoor unit .
High pressure  and high temperature refrigerant coming from compressor enters in the the condenser. The temperature of refrigerant in condenser is very  high as compared to the surroundings temperature so the condenser ejects its heat because heat always flows from high temperature to low temperature. you might have seen a  fan in outdoor unit which  is fixed in front of condenser which ejects heat of condenser. vapor refrigerant converters into liquid in the end of condenser.

4. DRYER

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……HOW AIR CONDITIONER WORKS Liquid refrigerant coming from condenser enters into Dryer. Dryer has two functions-
  1. Refrigerant filtration
  2. moisture absorbing from the refrigerant

5. EXPANSION VALVE

 
The work of expansion valve now comes into light. Expansion valve expands the refrigerant so the temperature of refrigerant goes down. WOW! The refrigerant is now cooled. Refrigerant moves further…..working of air conditioning system Clean and moisture free refrigerant moves into the expansion valve. The function of expansion device is to lower down the pressure of refrigerant. A small hole is there in expansion device for lowering down the pressure of 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 come. That is it.

Now Lets look into main components of air conditioner.

1. COMPRESSOR
Compressor in air conditioning system is used to raise the pressure of the refrigerant that is coming from evaporator coil so it creates a pressure difference between evaporator and condenser.

2. EVAPORATOR
evaporator is a coil made of  either cooper or aluminium 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….
3. CONDENSER Condenser is another coil which is used in the air conditioning system. condenser coil is connected with the evaporator coil with the help of some pipes. condenser is located in 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

Expansion valve is used to decrease the pressure of liquid refrigerant and it also cools down the liquid refrigerant further. Expansion valve is located in indoor unit.
This is the whole working of air conditioner.
