In central air conditioning systems, air is passed over coils chilled by water, by brine, or by direct expansion of a volatile refrigerant. … Refrigeration, or cooling, occurs when the liquid refrigerant absorbs heat by evaporation, generally at low temperature and pressure.

What is the difference between air conditioning and refrigeration?
In refrigeration, there is a transfer of thermal energy from a place at a cold temperature to a place at a higher temperature.
In AC, thermal energy is taken away to keep the air at a cool temperature. … The key difference between refrigeration and air conditioning lines in the supply point.
What is the importance of refrigeration and air conditioning?
The refrigeration process removes heat from an enclosed space to reduce and maintain the temperature for the contents of that space.
While air conditioning regulates the air in a large building, refrigeration solely cools and is generally used in a smaller space.
How does refrigeration air conditioning work?
Air conditioners use refrigeration to cool the air indoors through a physical law: when a liquid converts to a gas, it absorbs heat.
Air conditioning systems take advantage of this by forcing refrigerant compounds to evaporate and condense repeatedly in a closed system of coils.
What is the main purpose of air conditioning?
The primary purpose of air conditioning is to create a room climate comfortable for humans. Some special type of conditioning system is used to cool the temperature of electric devices.
It controls the humidity of a room as 30 to 65% is permitted while the temperature should be between 20 and 26 degrees Celsius.
