Problems solved by technology

The disadvantages of this kind of ice storage unit are: 1. On the basis of the original refrigerating unit, there is a big change, and additionally, the brine and brine pump are required, which is complex in structure and high in cost; 2. This kind of ice storage unit only has cold storage function, but no heat storage function; 3. This kind of ice storage unit cannot improve the supercooling degree of the refrigeration unit

Abstract

In the invention, a supercooled ice cold-storage unit comprises an ice-storage device, a closed circulating pipeline and three external connection points. On the closed circulating pipeline passing through the ice-storage device there is a electronic expansion valve and three magnetic valves, and one magnetic valve is in parallel connection with the electronic expansion valve and the other magnetic valves are in parallel. The first external connection point is located on one side of the electronic expansion valve, the second one is located between the magnetic valve and the ice-storage device and the third one is located at once end of the magnetic valve.

Description

technical field [0001] The invention relates to an air-conditioning system and an air-conditioning assembly, in particular to an ice cold storage unit. Background technique [0002] The existing ice-storage air-conditioning system uses the cheap electricity in the low-load period of the power grid, such as nighttime electricity, to store the cold energy produced by the refrigeration system in water through the refrigerant (usually ethylene glycol aqueous solution), and freeze the water into Ice; and in the high-load period of the power grid with expensive electricity prices, such as daytime, the cold energy in the ice is released to supply cooling to the air-conditioning system, thereby reducing the demand for power during the high-load period of the power grid and realizing the "peak-shifting and valley-filling" of the power system Air Conditioning System. In areas with tight power supply, the ice storage system can realize "load transfer"-transfer the cooling load during ...
