The primary principles of the refrigeration process, or cycle, are the absorption of the amount of heat required for the change of state from a liquid to a vapour by evaporation and the release of that amount of heat required for the change of state from a vapour back to a liquid by condensation.
Mechanical Engineering Notes (Study Materials) for IES PSUs GATE in Refrigeration & Air Conditioning (RAC).
Refrigeration and air conditioning are two terms that are used interchangeably. An RAC air conditioner is a rectangle or square appliance that cools and/or heats a single room and is connected to a wall or window. An air vent on the front of the machine distributes the air.
Refrigeration and air-conditioning (RAC) engineers create, install, and maintain cooling systems in structures such as supermarkets, offices, schools, hospitals, and food processing industries.
