The principle of flash cooling is achieved in _______________ Correct Answer steam-jet refrigeration

Steam-jet refrigeration is employed by chemical agent machines to achieve mechanical refrigeration. Water is used as refrigerant. These are used where chilled water is required where the temperature is more than 5°C. The principle of flash cooling is achieved in steam-jet refrigeration.
