Basic   Airconditioning  working system

A basic airconditioning has  few  main components which  works on principles of
thermodynamics  these are  Compressor , Condenser , Evaporator  ,  Thermostatic  Valve and
Refrigerant .

Refrigerant  ( R-22, R-12 , R-410A,R-134A) in compressors   is responsible  for the heat
transfer and it does through  changing its state from  gas to liquid and then liquid to gas  during
 air conditioning cycle .

Hot  refrigerant   gas moves  to condenser ( air cooled or  water cooled )where  its cooled  
down by either water or air . heat transfer takes from hot refrigerant to ambient air which takes
away the heat  . This has impact on refrigerant which then starts  changing into liquid form .
Thermostatic valve then monitors  the quantity of refrigerant to pass on to evaporator .  we can
call it as metering device which is an orifice which allows right amount of refrigerant to  
evaporator .

Evaporator  now changes  complete  refrigerant into  vapour or gas  due  to heat transfer from
warm air to  refrigerant  which takes heat to convert itself into gas thus cooling the surface of
coils which then makes the air cool inside the room or the hall .

Refrigerant then comes back to the compressor thus complete the cycle  of  air conditioning .
this goes on until desired temperatures is achieved . The suction line  is the low pressure , low
temperature  gas from evaporator to the compressor and discharge line is the one which
pushes high pressure and high temperature  gas to the condenser thus creating a pressure
difference which  makes refrigerant to flow into system
