Description
Technical Field
[0001] The utility model relates to the field of cold storage, in particular to an energy-saving device for a double-temperature cold storage. Background Art
[0002] A dual-temperature cold storage is a cold storage that is divided into two single rooms with different temperatures by adding partitions, and two sets of doors are installed respectively. Different temperatures are designed according to the needs of storing food, and the functions of preservation and refrigeration can be realized at the same time. The refrigeration unit uses a centralized cooling system, and the two sets of evaporators in the storage are cooled at the same time. The temperature control system can independently display and control the different temperatures of each room. Because a one-machine dual-control system is used to control the two temperatures, when the temperature of one room reaches the set requirement, the control system will turn off the refrigeration of this room, and the refrigeration unit will not stop working until the temperature of the other room also reaches the set requirement. Before starting the machine, the automatic control system will control the refrigeration unit to realize the refrigeration of the room whose temperature reaches the set requirement first. With the respiration of vegetables or other items in the cold storage, the temperature in the cold storage will rise. High, as long as the temperature in one of the cold storages reaches the upper temperature limit, the refrigeration unit needs to be turned on for cooling. When the two cold storages reach the upper temperature limit one after another, the refrigeration unit will be frequently started, which will cause energy waste. An energy-saving device for a dual-temperature cold storage disclosed in the existing application No. CN202221345872.8 uses the low-temperature gas in the freezer to cool the fresh-keeping storage until the freezer and the fresh-keeping storage reach the upper temperature limit, and then turns on the refrigeration unit to work on the freezer and the fresh-keeping storage at the same time, reducing the switching frequency of the refrigeration unit and extending the service life of the refrigeration unit. Using the low-temperature gas in the freezer to cool the fresh-keeping storage will cause the temperature in the freezer to rise rapidly, affecting the freezing effect of the freezer.

[0005] Through the above technical scheme, when the cold air is used to cool the fresh-keeping room, the cold air can be allowed to enter the gas cylinder for storage through the three-way pipe, and the cold air in the gas cylinder can be prevented from heating up by injecting refrigerant into the refrigerant cavity. When the temperature in the fresh-keeping room reaches the upper temperature limit, the solenoid valve is opened by the temperature control switch. At this time, the cold air in the gas cylinder will enter the fresh-keeping room to cool down the fresh-keeping room, thereby avoiding the use of low-temperature gas in the freezer to cool down the fresh-keeping room and ensuring the freezing effect of the freezer.

When the cold air in the air cylinder is exhausted, the outside air can be pumped into the air cylinder through the vacuum pump. The heat exchange between the outside air and the refrigerant will quickly cool down. After cooling, it is convenient to pass the cold air into the fresh-keeping room, and the outside air can be filtered through the filter box.
[0008] The beneficial effects of the utility model are as follows:
[0009] 1. When cooling the fresh-keeping room with cold air, the cold air can be stored in the gas storage cylinder through the three-way pipe.

By utilizing the elastic force of the spring and the gravity of the movable plate, the cold air in the air cylinder can smoothly enter the fresh-keeping room after the solenoid valve is opened. When the cold air in the air cylinder is exhausted, the outside air can be pumped into the air cylinder through the vacuum pump.
