| Abstract: | The development on CO 2 transcritical refrigeration cycle has drawn much attention recently for its environmental friendliness. Several applicable conditions of transcritical refrigeration cycle were studied on the base of the first and the second law of thermodynamics. Some requirmements for transcritical refrigeration cycle, including the surrounding temperature, the refrigeration pressure and temperature and the regeration temperature difference, were analyzed in particular. The startup crisis was obtained, and minimum refrigeration pressure difference was determined. The results were used in analysis of CO 2 refrigerant, and corresponding data was applied in studying on application of CO 2 transcritical refrigeration system. |
