Air Conditioner Assembly

Today is the fifth  day of my Industrial Training and today we are to learn how to assemble an Air Conditioner...
Air conditioning (AC) is the process of altering the properties of air, primarily temperature and humidity, to more comfortable conditions, typically with the aim of distributing the conditioned air to an occupied space to improve thermal comfort and indoor air quality.
Window unit air conditioners are installed in an open window. The interior air is cooled as a fan blows it over the evaporator. On the exterior the heat drawn from the interior is dissipated into the environment as a second fan blows outside air over the condenser.
.The main component of an AC are:
COMPRESSOR: Compresses the refrigerant from low pressure (low temperature) to high pressure (high temperature). This conversion raises the boiling point to higher temperature levels, facilitating elimination of the heat brought by the outdoor air.
CONDENSER: This component receives gas at high pressure and high temperature from the compressor. In air-cooled condensers, the metallic surfaces cool the gas which changes status and turns to liquid. In the case of water-cooled condensers, it is the circulation of the water that produces the same cooling effect.
EVAPORATOR: A fan blows the warm air (which is to be cooled) across the evaporator, causing the liquid part of the cold refrigerant mixture to evaporate as well, further lowering the temperature. The warm air is therefore cooled.
CONTROL PANEL: Where you select the temperature, quantity and location of air to come from the heater/ conditioning system

Some of the Process applications include these:
Chemical and biological laboratories, Cleanrooms, Environmental control of data centers,Facilities for breeding laboratory animals, Food cooking and processing area,Hospital operating theatres
I realized that not only the air is conditioned but our life is conditioned too... truly an Engineering wonder enables cool, pure, fresh air at your finger tips...the motto is "feel cool, think cool"...
