| Abstract: | The objectives of this paper are to improve the double-stage compression system,and build up a new quasi-tertiary vapor-compression refrigeration system.An air-compensating system was added which is composed of flash vessel to low-pressure compression part.According to the theoritical caculation,it showed that the COP and cooling capacity of the quasi-tertiary vapor-compression refrigeration system are much better than that of the double-stage compression refrigeration system. |
