のである。An object of the present invention is to provide a refrigerant with an improved coefficient of performance. The coefficient of performance here is expressed as refrigerant capacity/compression work, where refrigeration capacity is the amount of heat removed from the object to be cooled per unit time, and compression work is the amount of power required to operate the refrigerator per unit time. The coefficient of performance corresponds to the efficiency of the refrigerant.

るＩＪｉ現な知見に基き本発明を完成するに至った。As a result of research into refrigerants with improved coefficients of performance, the present inventors found that dichlorodifluoromethane (Freon-12) and chlorodifluoromethane (Freon-12) and chlorodifluoromethane (chlorodiflu-1) can be produced by blending promotrifluoromethane and chlorodifluoroethane.
It has been discovered that a refrigerant with an improved coefficient of performance exceeding that of methane (Freon-22) can be obtained, and the present invention has been completed based on this current knowledge.

In the composition range of 5 to 90% by weight, the refrigeration capacity is significantly large. The capacity is greater than that of Freon-12 as well as Freon-22.

クル用の媒体としても好適である。The refrigerant according to the present invention has a specific heat ratio smaller than that of Freon-12 and Freon-22, and the discharge gas temperature of the compressor is lower than that of Freon-12 and Freon-22.
- It is also suitable as a medium for relatively high-temperature freezing cycles such as pump-type air conditioners.

器として兼用覆ることができる。Note that the refrigerant according to the present invention has a fire extinguishing effect because it contains promotrifluoromethane. Therefore, by releasing the refrigerant from the refrigerator in the event of a fire, the refrigerator can also be used as a fire extinguisher.

右する。The refrigerant of the present invention is a non-azeotropic composition. In general, for single compounds and azeotropic compositions, the evaporation temperature in the evaporator is constant because the evaporation takes place under constant pressure, but for non-azeotropic compositions, the temperature is low at the evaporator inlet. Then, the temperature becomes high at the evaporator outlet. On the other hand, the fluid to be cooled (well, it flows against the flow of refrigerant in the evaporator so that heat is exchanged with it, and even if the evaporation temperature of the refrigerant is constant, the temperature gradient changes along the flow.

たものである。That is, within the evaporator, the temperature difference between the refrigerant and the fluid to be cooled becomes smaller as the fluid to be cooled advances. In the present invention, by using a non-azeotropic refrigerant as the refrigerant, it is possible to approach the temperature gradient of the fluid to be cooled in the evaporator, resulting in improved refrigeration efficiency and an excellent coefficient of performance. It has become something.
