Refrigeration Cycle
➤
A Closed cycle of evaporation, compression,
and condensation.
➤
Transfer of Heat energy between two environments.
Evaporation
➤
The process of liquid becoming vapor/gas and it
takes place in evaporator coil of an air-conditioner.
➤
This part of the system gets cold to the touch
(about 7°C/ 45°F) during it’s operation.
Compression
➤
The process of reducing the volume of a gas/ vapor
is called compression.
➤
The compressor pumps gaseous refrigerant to a
high pressure and temperature.
Condensation
➤
The process of gas turning into liquid state is called
condensation
➤
It allows refrigerant to transfer heat without mixing.
Refrigerant
➤
The working fluid in refrigeration
cycle is called refrigerant.
➤
Modern AC's hydro flouro carbons
that are inflammable, non-corrosive.
➤
Most widely used refrigerant in
residential AC's nowadays are R32.
