Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of frozen water temperature range low, accurate, stable, and efficiency is high and the frozen water unit of energy-conserving and environment-protective.
For achieving the above object, the frozen water unit that the utility model provides, wherein, the condenser that comprises frame, be provided with in frame, the compressor being provided with on condenser, the oil content being provided with on condenser, the evaporation tube sheet, the ice model tank being provided with below evaporation tube sheet that are communicated with condenser and oil content respectively, and the water circulating pump being provided with on ice model tank.Between condenser and evaporation tube sheet, be provided with the liquid-dividing head being interconnected, between liquid-dividing head and condenser, be provided with the expansion valve being interconnected, between liquid-dividing head and expansion valve, be provided with the heating tube being interconnected, on heating tube, be provided with magnetic valve, evaporation tube sheet top is provided with the sprinkler pipe being communicated with water circulating pump.
In some embodiments, the second shell that evaporation tube sheet is provided with by the first shell with on the first shell forms.On the first shell, be provided with the first import being communicated with expansion valve, on the second shell, be provided with the second import being communicated with oil content.Intersection between the first shell and the second shell is provided with the outlet being communicated with liquid-dividing head.Outlet is communicated with compressor.
In some embodiments, evaporation tube sheet is many groups.
In some embodiments, between outlet and compressor, be provided with gas-liquid separator.
The beneficial effects of the utility model are that frozen water temperature range is low, accurate, stable, and efficiency is high and energy-conserving and environment-protective.Because the liquid refrigerant of discharging from condenser is after expansion valve effect, after liquid-dividing head shunting, flow in evaporation tube sheet and carry out heat exchange with the water on evaporation tube sheet surface, and discharge from the outlet of evaporation tube sheet, be back to again again compressor, whole process circulates.Utilize water circulating pump by the water in ice model tank, be pumped back to sprinkler pipe and recycle.Above-mentioned these two circulate process and not only can improve the icing effect in evaporation tube sheet surface, the temperature that simultaneously also can ensure to be shed to frozen water in ice model tank from evaporation tube sheet is at 0 DEG C to 2 DEG C or remain on 2 DEG C, realize frozen water temperature range low, accurate and stable, and the high technique effect of efficiency.In addition, the water in ice model tank and the liquid refrigerant of evaporation in tube sheet can cycling and reutilizations, also realized the object of energy-conserving and environment-protective.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, utility model is described in further detail.
As shown in Figure 1, frozen water unit, the condenser 2 that comprises frame 1, be provided with in frame 1, the compressor 3 being provided with on condenser 2, the oil content 4 being provided with on condenser 2, the evaporation tube sheet 5, the ice model tank 6 being provided with below evaporation tube sheet 5 that are communicated with condenser 2 and oil content 4 respectively, and the water circulating pump 7 being provided with on ice model tank 6.Between condenser 2 and evaporation tube sheet 5, be provided with the liquid-dividing head 9 being interconnected, between liquid-dividing head 9 and condenser 2, be provided with the expansion valve 8 being interconnected, between liquid-dividing head 9 and expansion valve 8, be provided with the heating tube 18 being interconnected, on heating tube 18, be provided with magnetic valve 17.Evaporation tube sheet 5 tops are provided with the sprinkler pipe 10 being communicated with water circulating pump 7.Above-mentioned compressor 3 is mainly made up of shelf, compressor body, control device.
The second shell 12 that evaporation tube sheet 5 is provided with by the first shell 11 with on the first shell 11 forms.On the first shell 11, be provided with the intersection being provided with between the second import 14, the first shells 11 and the second shell 12 being communicated with oil content 4 on the first import 13, the second shells 12 that are communicated with expansion valve 8 and be provided with the outlet 15 being communicated with liquid-dividing head 9.In addition, outlet 15 is communicated with compressor 3.
Above-mentioned evaporation tube sheet 5 is many groups.And be provided with gas-liquid separator 16 between outlet 15 and compressor 3.
Operation principle comprises cool cycles process, deices process and ice water circulation process.
(1) kind of refrigeration cycle process
After sprinkler pipe is opened, compressor 3 by liquid refrigerant in oil content 4 is transported to condenser 2, output to expansion valve 8 from condenser 2 other ends afterwards, after the effect of expansion valve 8, input cooling liquid refrigerant, by the inside of inputting evaporation tube sheet 5 after liquid-dividing head 9 separatory from the first import 13 and the second import 14, then evaporate the inner colded liquid refrigerant of tube sheet 5 and surperficial water and carry out heat exchange.Until the water cooling on evaporation tube sheet 5 surfaces is become to ice cube.Then by the liquid refrigerant after heat exchange from exporting 15 discharges, finally undertaken, after gas-liquid separation, being transmitted back to compressor 3 by gas-liquid separator 16.So periodic duty.
