Description

Technical Field

[0001] The utility model relates to the technical field of ice making, in particular to an ice making system. Background Art

[0002] With the improvement of the quality of life, people need to use more and more electrical appliances, especially in the hot summer, ice cubes have become important in people's daily life and industrial applications. Generally, an ice maker is needed to make ice cubes, and the ice cubes need to be stored in the ice storage body. The thermal insulation performance of the ice storage body determines the storage time of the ice cubes. If the thermal insulation performance of the ice storage body is not good, it will be easier to cause the ice to melt quickly, which not only wastes resources, but also greatly reduces the unit ice output, bringing a poor experience to users. Especially in summer, when the outside temperature is high, the ice storage body needs to be continuously refrigerated, which undoubtedly increases production energy consumption. At the same time, in the existing ice making system, when the refrigerant returns to the compressor after a cycle, there may be completely evaporated refrigerant that will return to the compressor in a liquid state, causing liquid hammer in the compressor, causing damage to the compressor.

[0003] Therefore, it is necessary to design an ice making system to solve the above problems. Utility Model Content

[0006] The outlet of the compressor is connected to the inlet of the condenser; the outlet of the condenser is connected to the first inlet of the liquid cooling device; the first outlet of the liquid cooling device is connected to the inlet of the evaporator of the ice maker; the outlet of the evaporator of the ice maker is connected to the inlet of the ice storage device; the outlet of the ice storage device is connected to the second inlet of the liquid cooling device; the second outlet of the liquid cooling device is connected to the inlet of the compressor.

[0007] The liquid cooling device includes a sealed tube body and a spiral pipeline arranged inside the tube body; the inlet and outlet of the spiral pipeline are respectively the first inlet and the first outlet; two connecting pipes communicating with the inside of the tube body are also provided at both ends of the tube body; the two connecting pipes are respectively the second inlet and the second outlet.

[0008] The second inlet and the second outlet are centrally symmetrically arranged.

[0009] The ice storage device comprises an ice storage body and a cooling pipeline; the cooling pipeline is attached to the back surface, the bottom surface and the two side walls of the ice storage body in an S shape.

[0010] The material of the ice storage body is aluminum; the material of the cooling pipeline is copper.

[0011] A drying filter and a throttle valve are sequentially connected in series between the first outlet of the liquid cooling device and the inlet of the evaporator of the ice maker.

[0012] The condenser is an air-cooled condenser.

[0013] By adopting the above technical scheme, the utility model has the following beneficial effects: a circulation loop is formed among the compressor, condenser, liquid cooling device, ice maker and ice storage device of the utility model, and the liquid cooling device is used to exchange heat between the refrigerant flowing out of the ice storage device and the refrigerant flowing out of the condenser. The refrigerant of the utility model starts from the compressor, passes through the liquid cooling device, the evaporator of the ice maker, and the ice storage device in sequence, and then enters the liquid cooling device to exchange heat with the refrigerant flowing out of the condenser before returning to the compressor. In this process, the refrigerant is not only used to make ice, but also to keep the ice storage device warm, so that the ice cubes can be preserved for a long time without increasing energy consumption, thereby saving energy. At the same time, the heat exchange of the refrigerant through the liquid cooling device will increase the superheat of the system. At this time, when the refrigerant returns to the compressor after the superheat is increased, there will be no wet stroke, thereby avoiding the risk of compressor liquid hammer.

[0019] (Example 1)

[0020] See Figure 1 and Figure 2An ice-making system of the present embodiment includes a compressor 1, a condenser 2, a liquid cooling device 3, an ice-making machine 4 and an ice storage device 5; a circulation loop is formed among the compressor 1, the condenser 2, the liquid cooling device 3, the ice-making machine 4 and the ice storage device 5; the liquid cooling device 3 is used for exchanging heat between the refrigerant flowing out of the ice storage device 5 and the refrigerant flowing out of the condenser 2.

[0021] Furthermore, the outlet of the compressor 1 is connected to the inlet of the condenser 2; the outlet of the condenser 2 is connected to the first inlet of the liquid cooling device 3; the first outlet of the liquid cooling device 3 is connected to the inlet of the evaporator of the ice maker 4; the outlet of the evaporator of the ice maker 4 is connected to the inlet of the ice storage device 5; the outlet of the ice storage device 5 is connected to the second inlet of the liquid cooling device 3; the second outlet of the liquid cooling device 3 is connected to the inlet of the compressor 1.

[0022] Furthermore, the liquid cooling device 3 includes a sealed tube body and a spiral pipeline arranged inside the tube body; the inlet and outlet of the spiral pipeline are respectively the first inlet and the first outlet; two connecting pipes connected to the inside of the tube body are also provided at both ends of the tube body; the two connecting pipes are respectively the second inlet and the second outlet.

[0023] Furthermore, the second inlet and the second outlet are centrally symmetrically arranged to reduce the flow rate of the refrigerant and improve the heat exchange effect.

[0024] Furthermore, the ice storage device 5 includes an ice storage body 5-1 and a cooling pipe 5-2; the cooling pipe 5-2 is attached to the back, bottom and two side walls of the ice storage body 5-1 in an S shape, so that the contact between the cooling pipe 5-2 and the ice storage body 5-1 is more complete, further improving the insulation effect of the ice storage body 5-1.

[0025] Furthermore, the material of the ice storage body 5-1 is aluminum; the material of the cooling pipeline 5-2 is copper, so that the ice storage body 5-1 and the cooling pipeline 5-2 have good thermal conductivity, thereby further improving the heat preservation effect of the ice storage body 5-1.

[0026] Furthermore, a drying filter 6 and a throttle valve 7 are connected in series between the first outlet of the liquid cooling device 3 and the inlet of the evaporator of the ice maker 4, so as to filter impurities and moisture in the system and adjust the flow rate of the refrigerant.

[0027] Preferably, the condenser 2 is an air-cooled condenser.

[0028] The working principle of this embodiment: Usually, the temperature of the refrigerant when it evaporates from the ice maker 4 is -20 to -23°C, and the temperature of the refrigerant going out of the evaporator of the ice maker 4 is -18 to -20°C. The return air temperature at this time is still relatively low. If it returns directly to the compressor 1, the refrigerant at this time is likely to be in a liquid state, and there is a risk of causing liquid hammer in the compressor 1. In this embodiment, the refrigerant at -18 to -20°C that has not been completely evaporated is passed into the ice storage device 5 to cool the ice storage device 5, thereby ensuring the storage effect of ice cubes. At the same time, the refrigerant coming out of the ice storage device 5 will increase the superheat of the system after heat exchange with the refrigeration coming out of the condenser 2. At this time, the refrigerant will return to the compressor 1 after the superheat is increased, and there will be no wet stroke, thereby avoiding the risk of liquid hammer in the compressor 1.

[0029] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
