7. Parts and components of window Air - conditioner
Compressor:-
The compressor is the heart of the refrigeration system. It circulates the refrigerant around the system. It sucks the low temperature refrigerant vapour, compress it. The vapour turns to high pressure and high temperature vapour and to condenser by discharge line.

8. 2. Condenser:-
Condenser is a heat transferring device to change the gas or vapour discharged by compressor to liquid to ready for the use in the evaporator.

9. 3. Filter Drier:-
It is fitted in liquid line before capillary. It strain the dust and dirt. Absorb moisture in the system. It is filled with silica gel to absorb moisture.

10. 4. Capillary tube :-
It is a metering device in domestic refrigerators and air conditioners. The capillary tube consists of small diameter copper tube. The lengths of which depends upon the size of condensing unit and the kind of refrigerator used.

11. 5. Evaporator :-
Any heat transfer surface area in which a refrigerant vapourizing for the purpose of removing heat from the medium being cooled.
