Refrigeration is a process of removing heat from a low-temperature reservoir and transferring it to a high-temperature reservoir. The work of heat transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism, electricity, laser, or other means.
The principle behind working of A.C. is same as that of refrigerator. A.C. works on the mechanism of refrigerant liquid. ... Any A.C. will comprise of three parts i.e. a compressor, a condenser and an evaporator. Compressor and condenser are usually kept outside the house where as an evaporator is kept inside the house.
