Refrigeration equipment for sea cucumber seedlings

Abstract

The present invention relates to a refrigeration equipment for raising sea cucumber seedlings, comprising a first automatic liquid-cooled screw compressor unit, a second automatic liquid-cooled screw compressor unit, a first ice-water plate changing unit and a second ice-water plate changing unit, the The ports corresponding to the first ice-water plate exchange unit and the second ice-water plate exchange unit are connected to each other, and the corresponding ports of the first automatic liquid-cooled screw compressor unit and the second automatic liquid-cooled screw compressor unit are connected to each other. Between the ports of the first ice-water plate exchange unit and the second ice-water plate exchange unit and the corresponding ports of the first automatic liquid-cooled screw compressor unit and the second automatic liquid-cooled screw compressor unit, a first pipeline, a second Pipeline, Third Pipeline, Fourth Pipeline, and Fifth Pipeline. The invention has the advantages of improving refrigeration efficiency, reducing maintenance work, and eliminating the danger of affecting production due to ammonia leakage of the evaporator.

Description

technical field [0001] The invention relates to a refrigeration device for raising sea cucumber seedlings, and relates to the field of refrigeration. Background technique [0002] Sea cucumber seedlings and cultivation have the characteristics of short breeding cycle, fast growth, high breeding output, and high economic value. They are cultivated in both the north and south coasts of my country. The existing problems of the prior art are: one, once the evaporator of the refrigeration equipment leaks ammonia, it will affect the water quality of the seedlings and bring irreparable losses to the production of the seedlings. The second is a serious waste of energy. In the process of raising sea cucumber seedlings, hundreds of tons of low-temperature seawater are added to the seedling water system every day, and hundreds of tons of low-temperature seawater are discharged into the sea at the same time, resulting in a large waste of energy. [0003] For example, the Chinese patent...

AI Technical Summary

Problems solved by technology

The existing problems in the prior art are: one, once the evaporator of the refrigeration equipment leaks ammonia, it will affect the water quality of the seedlings and bring irreparable losses to the seedlings.

The second is the serious waste of energy. In the process of raising sea cucumber seedlings, hundreds of tons of low-temperature seawater are added to the seedling water system every day, and hundreds of tons of low-temperature seawater are discharged into the sea at the same time, resulting in a large waste of energy.

Its disadvantages are: due to the disadvantages of structural design, in actual operation, the problem of ammonia leakage from the evaporator cannot be solved, and there are potential safety hazards
