| 摘要 |
Such a central refrigeration plant comprises, for each temperature, a refrigeration assembly consisting of a cold-production stage, the evaporation of which is connected via an exchanger to a refrigeration distribution circuit which comprises at least one refrigerator, in which circuit a cryogenic fluid circulates. According to the invention, the refrigeration assemblies (A, B and CD) are interconnected, according to the decreasing temperatures at which they function, by means of an exchanger (28) between the refrigeration distribution circuit (B) of the refrigeration assembly at the highest temperature and the condenser of the cold-production stage (C) of the refrigeration assembly at the lowest temperature. Application in particular in central refrigeration plant used in hypermarkets. <IMAGE> |
