A cold storage device with adjustable cold storage and cooling release rates

Abstract

The invention discloses a velocity-adjustable cold accumulation device. The velocity-adjustable cold accumulation device comprises a sealed housing; a fluid inlet is formed in the upper part of the housing; a fluid outlet connector is formed in the lower part of the housing; a plurality of layers of cold accumulation plates are arranged in the housing; a plurality of cold accumulation elements aredistributed on the cold accumulation plates, wherein the cold accumulation elements are in regular hexagonal shapes; cold accumulation materials are packaged in the cold accumulation elements; the bottoms of the cold accumulation elements are detachably mounted on the cold accumulation plates; the cold accumulation materials are foamed metal materials; and flow channels imitating a cellular structure are formed between the cold accumulation elements. The cold accumulation elements are filled with the foamed metal materials through the cold accumulation elements imitating the cellular structure, the cold accumulation elements are distributed to form the cold accumulation plates, the cold accumulation plates are overlaid to form the cold accumulation device, and the quantities of the cold accumulation plates and the cold accumulation elements in the cold accumulation device can be adjusted as required, so that the purpose of adjusting the cold releasing velocity is realized.

Description

technical field [0001] The invention belongs to the technical field of cold storage and designs a cold storage device with adjustable cold storage and cold release rates. Background technique [0002] After the energy crisis in the 1870s, in view of the fact that the cold storage air-conditioning system can improve the power supply efficiency of urban and regional power grids and balance the load of the power grid; at the same time, in areas with reasonable peak and valley electricity prices, it will help users save operating costs, and many countries have begun to use cold storage. The technology is applied to the air-conditioning system as a means of peak regulation of electric load. Among them, the United States has built about 1000-2000 cold storage systems in the early 1990s, and Japan established energy conservation and load equalization as basic national policies in the 1990s, and by 2001 there were more than 4000 cold storage projects. my country began to build cold...

AI Technical Summary

Problems solved by technology

Although Japan is currently at the forefront in the miniaturization of cold storage air conditioners, the construction space occupied is still relatively large, and the density of cold storage needs to be increased. Slow, there are problems such as poor temperature uniformity, unstable cooling rate in the middle and late stages of release, incomplete cooling release, and low energy utilization rate.
