Ice maker

Abstract

The invention relates to an ice maker. The ice maker comprises a refrigerant loop system, a secondary refrigerant bypath system and a heat exchanger, wherein a refrigerant capable of circularly flowing is sealed in the refrigerant loop system; the secondary refrigerant bypath system comprises an ice making component; a secondary refrigerant capable of circularly flowing is sealed in the secondaryrefrigerant bypath system and is always in a liquid state when circularly flowing in the secondary refrigerant bypath system; the heat exchange is shared by the refrigerant loop system and the secondary refrigerant bypath system and is used for exchanging heat between the refrigerant which flows through the downstream side of a throttling device of the refrigerant loop system and the secondary refrigerant which flows through the downstream side of the ice making component of the secondary refrigerant bypath system; and the ice making component can rotate around a rotating shaft and is provided with ice surface contacted with water. In the ice maker, the secondary refrigerant which is always in the liquid state is used for making ice, and only a common machinery seals are arranged on a secondary refrigerant inlet and outlet of the ice making component, so that the problem of refrigerant leakage during rotation ice making in a drum-type ice making device is solved.

Description

technical field [0001] The invention belongs to the field of refrigeration equipment, and relates to a drum-type ice-making device, which is suitable for producing seawater ice or freshwater ice, especially a refrigeration equipment for producing phosphorus flake ice and snow in freshwater ice. Background technique [0002] At present, there are many kinds of drum ice machine systems, each with its own advantages and disadvantages, but the basic refrigeration principle is to use the evaporator in the refrigeration system to rotate directly to make ice, and the outer surface of the evaporator is the ice forming surface. We know that the refrigerant in the evaporator is mostly in the gaseous state when it is refrigerated and evaporated. If the entire circuit cannot be sealed, the refrigerant will leak. Therefore, for general small and medium-sized refrigeration equipment, in the prior art The refrigerant in the refrigerant circuit system is completely sealed. However, when th...

AI Technical Summary

Problems solved by technology

However, because the sealing elements in the prior art can only achieve a good effect on liquid sealing, it is difficult to ensure complete sealing for some gaseous substances with small molecular diameters, especially these gaseous substances are still in constant motion, which is even more difficult to achieve. good sealing effect

It is precisely because of the inability to find a reliable sealing element that most of the existing roller ice machines have refrigerant leakage problems, and this leakage is uncontrollable, and users cannot know when the refrigerant needs to be replenished

This drawback is very serious when the ice machine is operating in the field or at sea
