Abstract (en)
[origin: EP1862749A2] A vapor compression refrigerating cycle (10) has a compressor (1), a radiator (2), an oil separator (3) for separating the refrigerant radiated by the radiator (2) into refrigerant and oil containing a small amount of refrigerant, a first pressure reducer (6), an evaporator (7), and an accumulator (8), wherein a second pressure reducer (5) for reducing a pressure of the oil containing a small amount of refrigerant separated by the oil separator (3) and an inside heat exchanger (4) for exchanging heat between the refrigerant separated by the oil separator (3) and the oil containing a small amount of refrigerant reduced in pressure by the second pressure reducer (5) are provided, and the oil containing a small amount of refrigerant is injected into a midway of the compression step of the compressor (1) after being passed through the inside heat exchanger (4). Utilizing the oil containing a small amount of refrigerant separated by the oil separator, the performance of the refrigerating cycle is improved, and it becomes possible to integrate respective equipment with each other, and while the refrigeration ability can be increased, problems on space and weight can be solved.
