AIR COOLEDWATER COOLED
Air conditioning(often referred to as aircon, ACor A/C) is the
process of altering the
properties air (primarily temperature and humidity) to more favourable
conditions. More generally, air conditioning can refer to any form oftechnological cooling, heating, ventilation, or disinfection that modifies
the condition of air.
AIR COOLED Air cooled air conditioning system involves the flow of air
as a medium to bring regulate temperature of a space.
WATER COOLED Water cooled air conditioning system involves the
flow of water as a medium to bring regulate temperature of a space.

Air conditioning (Air Cooled)
Room air conditioners come in two forms: unitary and packaged terminal (PTAC)
systems. Unitary systems, the common one room air conditioners, sit in a window
or wall opening, with interior controls. Interior air is cooled as a fan blows it over the
evaporator. On the exterior the air is heated as a second fan blows it over the
condenser. In this process, heat is drawn from the room and discharged to theenvironment. A large house or building may have several such units, permitting
