How does my AC work?
An <a href="http://www.kelvinsystems.co.in">air conditioner</a> cools and dehumidifies the air as is passes over a cold
coil surface. The indoor coil is an air-to-liquid heat exchanger with rows
of tubes that pass the liquid through the coil. Finned surfaces connected
to these tubes increase the overall surface area of the cold surface thereby
increasing the heat transfer characteristics between the air passing over
the coil and liquid passing through the coil. The type of liquid used depends
on the system selected. Direct-expansion (DX) equipment uses refrigerant
as the liquid medium. Chilled-water (CW) can also be used as a liquid medium.
When the required temperature of a chilled water system is near the freezing
point of water, freeze protection is added in the form of glycols or salts.
Regardless of the liquid medium used, the liquid is delivered to the cooling
coil at a cold temperature.
