Introduction of Window Room Air-Conditioner LESSON :- 01 Introduction of Window Room Air-Conditioner

OBJECTIVES State the meaning of A/C List the processes to be performed for A/C List the parts, components with their functions in A/C List the specifications of window A/C

1:- Air Conditioning The factors like temperature, moisture, air moment, pollution are affecting on the conditions of atmosphere and causing problems to human health and comfort. To overcome such problems air conditioner plays a vital role.

Process of Air Condition Filtering Cooling Circulation Humidifying Dehumidifying Heating

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.

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.

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.

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.

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