Two-stage refrigeration system with water removal function

Abstract

The invention discloses a two-stage refrigeration system with a water removal function. The two-stage refrigeration system comprises a first-stage cold water preparation and circulation system, a second-stage working medium direct-injection dynamic ice making circulation system, a cold water circulation system and a refrigerant replenishment device. According to the two-stage refrigeration system,the two-stage refrigeration systems of the two-stage refrigeration system with a continuous renewable water removal device are the first-stage cold water preparation system and the second-stage working medium direct-injection dynamic ice making and cold storage system, as a refrigeration working medium in the working medium direct-injection ice making system is directly injected in water to absorb heat to be evaporated into a gaseous state, a gaseous refrigerant carries water, and if the gaseous refrigerant is directly sucked into a compressor, the compressor is damaged, therefore, the renewable water removal device is installed in a second-stage working medium direct-injection gas suction circuit to prevent the damage to the compressor.

Description

technical field [0001] The invention relates to the technical field of refrigeration, and more specifically relates to a two-stage refrigeration system with the function of removing water. Background technique [0002] With the development of modern industry and the improvement of people's living standards, the application of air-conditioning equipment is becoming more and more extensive, and the energy consumption of air-conditioning accounts for as high as 30% of the total energy consumption of the national economy. Accounting for more than 20% of its peak electricity consumption. In order to alleviate the peak-valley load difference of the power system, many areas implement power cuts, which reduces people's quality of life. The ice storage technology is used to make ice and store cold by using low-peak electricity at night, and to melt the ice and cool it during the peak hours of the daytime electricity, so as to achieve peak shaving and valley filling, and balance the ...

AI Technical Summary

Problems solved by technology

To solve this problem, two-stage refrigeration systems are currently provided in the prior art, wherein the two-stage refrigeration systems are the first-stage cold water production system and the second-stage working fluid direct injection dynamic ice-making cold storage system, but due to the direct injection of working fluid In the ice system, the refrigerant is directly injected into the water to absorb heat and evaporate into a gaseous state. The gaseous refrigerant carries water. If it is directly sucked into the compressor, it will cause damage to the compressor.
