Domestic central refrigerating device

The utility model relates to a domestic device for centrally refrigerating, belonging to a refrigerating device. The device for centrally refrigerating is provided with a compressor, an output end of the compressor is connected with a condenser, and an output end of the condenser is simultaneously connected with two control valves which are respectively used for controlling a refrigerator and a freezer of an air-conditioner. After output ends of two evaporators are connected, and then are connected with the input ends of the compressor, the refrigerator and the freezer are positioned at the lower end, and the upper ends of the refrigerator and the freezer are connected with the air-conditioner. The device for centrally refrigerating positions the compressor and the condenser out of outdoors, indoor noise is reduced, and simultaneously the effects of ventilation and heat dissipation in the compressor are fine. The utility model has the advantages that one compressor can cause the refrigerator, the freezer, and the air-conditioner to work simultaneously, indoor occupation area is reduced, and cost is reduced.
