The invention discloses a cold accumulation type refrigerator and air-conditioner integrated device which comprises a refrigerator, an air-conditioner and cold energy conveying channels, wherein the refrigerator comprises an additional condenser and an automatic controller; the automatic controller is in charge of controlling operation of the additional condenser and on/off of control valves and a circulation electric pump on the cold energy conveying channels; the additional condenser of the air-conditioner is connected with the additional condenser of the refrigerator through the cold energy conveying channels. By adopting the cold accumulation type refrigerator and air-conditioner integrated device, cold energy can be stored in the refrigerator in the off peak power consumption period at night, and the stored cold energy can be supplied to the air-conditioner for refrigeration cooperatively in the peak power consumption period at daytime, so that a power distribution function of off peak electricity utilization of a power grid is achieved, the electricity expense is reduced, and the pressure of electric equipment to the power grid is alleviated.
