Zusammenfassung:The invention discloses a casting cooling process for a shell of a central refrigeration compressor. The casting cooling process comprises the following steps of: cooling a casting in a sand mold to be below 200 DEG C; opening the sand mold; taking the casting out and cleaning. According to the scheme, the casting is cooled in the sand mold along with the sand mold, so that a casting slow cooling effect in a thermal treatment furnace is achieved, and artificial aging treatment is substituted. The labor intensity is greatly relieved, the energy is saved, and the floor is saved.
