Abstract

The invention discloses cold storage equipment. The cold accumulation equipment comprises a cold storage part and a refrigerating unit, wherein the cold storage part comprises a first main body and ice storage parts, a first liquid storage cavity is formed in the first main body and used for storing a first cooling medium, the ice storage parts are arranged in the first liquid storage cavity, and a second liquid storage cavity is formed in the ice storage parts and used for storing a second cooling medium; the freezing point of the second cooling medium is lower than that of the first cooling medium; and the refrigerating unit comprises a second main body, wherein a third liquid storage cavity is formed in the second main body, and communicates with the second liquid storage cavity. By means of the design, the first cooling medium frozen in the first liquid storage cavity and the first cooling medium not frozen in the first liquid storage cavity give play to latent heat and sensible heat respectively, and therefore, the cold storage efficiency of the cold storage equipment is effectively improved. The invention further discloses a cold storage method adopting the cold storage equipment. The invention further discloses a regional cold supply system with the cold storage equipment.

Description

technical field [0001] The invention relates to the field of air conditioning and cooling, in particular to cold storage equipment, a method and a district cooling system. Background technique [0002] The district cooling system refers to a system in which cold water is produced at the cold storage equipment for buildings in a certain area, and is transported to each building through the transmission and distribution network for heat exchange and then supplied to users to meet the cooling load needs of users. [0003] At present, ice storage technology is adopted on a large scale in the district cooling system. By making ice at night and melting ice during the day, using peak and valley electricity prices, shifting peaks to fill valleys, and reducing peak power loads. In related technologies, the cold storage equipment often only utilizes the latent heat of the ice storage system, but does not fully utilize the sensible heat of the low-temperature water in the ice storage t...
