Abstract

PURPOSE: To recover oil droplets to an compressor with the coolant vapour which vaporizes sufficiently even in low refrigeration load, by arranging a bypass for mixing a portion of cooling water in a cooling-water system into the cooling water in a cooling-water system before cooled by the evaporator.
CONSTITUTION: When refrigeration load is reduced, and the ebullition phenomenon of coolant decreases, and the suction of oily mist becomes hard, a magnetic valve 12 is opened. Then, a portion of cooling water is bypassed from a cooling water inlet pipe 10 to a cooling water inlet pipe 8, and the coolant in an evaporator 1 is boiled. As a result of this, a tube is immersed in liquid coolant likewise in the whole load state, and oly mist is imhaled into a compressor 3, and sufficiently recovered by an oil recovery apparatus, and the oil portion in the evaporator 1 is reduced, and good heat-conduction performance is maintained
