Earth cold and ice storage cold combined refrigeration system

Abstract

The invention discloses an earth cold and ice storage cold combined refrigeration system, comprising a dehumidifying and cooling module, a cyclic cold supply module, an ice storage cold module and a capillary cold supply module, wherein the dehumidifying and cooling module feeds fresh air to the inside of a room after cooling and dehumidifying the fresh air, so as to adjust the indoor humidity; the capillary cold supply module carries out heat exchange together with indoor air through a capillary network heat exchanger, so as to adjust the indoor temperature to achieve separated control of the temperature and the humidity. By adopting the combined refrigeration system, outdoor gas is guided to the inside of the room through three heat exchange processes, so that the temperature of the outdoor gas is reduced and steam is discharged as much as possible; and then a part of heat is absorbed by a heat exchanger for returning temperature, so that not only is the comfort level of the combined refrigeration system adjusted, but also the content of vapor can be further reduced, so as to adjust the indoor temperature and humidity; a cold source used in cooling for the second time is supplied by the ice storage cold module and the capillary cold supply module; the ice storage cold module reduces the operating cost by using a peak valley price difference; the capillary cold supply module supplies cold by using the earth cold, so as to save an energy source.

Description

technical field [0001] The invention relates to the field of industrial refrigeration, in particular to a refrigeration and dehumidification system combined with ground cooling and ice storage. Background technique [0002] Due to the improvement of people's living standards, air conditioners are becoming more and more popular. However, due to the high energy consumption of air conditioners, the concentrated use of air conditioners has caused the gap between peak and valley electricity consumption in cities to increase day by day. In order to cut peaks and fill valleys of the power grid, energy storage air conditioners are now being advocated. A better option is to use ice storage systems, which can save a lot of operating costs for users. However, the ice storage system also has its own disadvantages. For example, the initial investment is large, and the refrigeration unit has a very low evaporation temperature during ice production, and its COP is reduced. Therefore, from...

Problems solved by technology

[0003] In order to solve the problems of increasing peak and valley gaps in urban electricity consumption and serious energy consumption caused by centralized use of air conditioners, the present invention provides a combined refrigeration and dehumidification system for ground cooling and ice storage. Ice is made during the low valley and the room temperature is adjusted by melting the ice during the peak of electricity consumption. The structure is simple and practical, and the purpose of energy saving, cooling and dehumidification is well realized.
