Problems solved by technology

This has very high requirements on the application occasions, but in actual use occasions, the high and low temperature cooling loads are rarely or always run at the same time. When only the high temperature cooling load or the low temperature cooling load is required to run alone, the aforementioned water temperature And the water layer is disordered, and the thermocline layer is greatly thickened, resulting in the waste of cold storage capacity, so it is impossible to fundamentally solve the technical problem

Embodiment Construction

[0020] For the convenience of those skilled in the art to understand, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, the water cold storage system with dual temperature section cooling function includes a cold storage tank 1, a refrigeration host 2, a high-temperature plate replacement component 3, a low-temperature plate replacement component 4, an upper water distribution component 5 and a lower water distribution component 6. The upper water distribution assembly 5 and the lower water distribution assembly 6 are respectively fixed at the upper end and the lower end of the cold storage water tank 1; the lower water distribution assembly 6 is connected to the cold side inlet of the cryogenic plate replacement assembly 4 through the first pipeline 7, and the The upper water distribution assembly 5 is connected to the cold-side outlet of the high-temperature plate...

Abstract

The invention discloses a water cold storage system with a double-temperature cold release function, comprising a cold storage water tank, a refrigerating main unit, a high-temperature plate exchange component, a low-temperature plate exchange component, an upper water distribution component, a lower water distribution component, a moving water distribution component, a sliding device and a temperature sensor. The invention overcomes the technical defects of an existing water cold storage system so that no matter in simultaneous run or independent run, the high-temperature plate exchange component and the low-temperature plate exchange component will not result in turbulence or crossing flow between a medium-temperature water layer and a high-temperature water layer, thus avoiding cold grade reduction and cold waste and improving utilization efficiency of cold capacity; meanwhile, an improvement is given in the comprehensive efficiency of the water cold storage system.

Description

technical field [0001] The invention relates to cold storage technology, in particular to a water cold storage system with the function of cooling in two temperature sections. Background technique [0002] Due to the obvious "peak-valley contradiction" in the load of the power grid between day and night, that is, the power load is high during the day and low at night. In order to encourage electricity consumption at night, there are different peak and valley electricity price policies across the country. For various types of refrigeration and low-temperature systems, such as central air-conditioning and industrial cooling systems, cold storage devices are added to the original system, and then low-cost electricity is used to store cold at night, and the stored cold is released during high-priced electricity during the day. The cooling operation method of partially or completely replacing high-priced electricity with low-priced electricity can bring obvious economic benefits...
