Abstract
The utility model relates to a refrigerating circulation system used for an ice-temperature storage house, which comprises a refrigerating machine, a condenser, a regulating valve and a control instrument, wherein the condenser is connected with the refrigerating machine. The utility model is characterized in that the refrigerating circulation system also comprises a heat exchanger and a secondary refrigerant supplying device, wherein the heat exchanger is respectively connected with the refrigerating machine, the condenser and the secondary refrigerant supplying device, the secondary refrigerant supplying device comprises a secondary refrigerant storage tank and a secondary refrigerant extraction pump connected with the secondary refrigerant storage tank, the secondary refrigerant extraction pump is connected in parallel with each evaporator in the ice-temperature storage house, a three-way electromagnetic valve is arranged on one each parallel connection branch, and a main loop of the secondary refrigerant supplying device is connected with the secondary refrigerant storage tank through the heat exchanger. After the adoption of the structure, the flow rate of the secondary refrigerant can be controlled through the three-way electromagnetic valve. The temperature can be reduced through the secondary refrigerant. Thereby, compared with the existing direct evaporation method, the utility model can easily realize uniformity and stability of the house temperature. In addition, the utility model has the advantages of simple structure, convenient installation and use and the like.
Description
Technical field
The utility model belongs to the storage technique field, particularly relates to a kind of ice Wen Ku cooling cycle system.
Background technology
Existing combination temperature of ice house control system, normally when Ku Wen is higher than 1 ℃ of design temperature, refrigeration system work; When Ku Wen is lower than 1 ℃ of design temperature, close refrigeration system.On the one hand, owing to there is thermal inertia, the actual temperature fluctuation of storehouse temperature is all greater than ± 1 ℃, and especially when the air-cooler defrosting, the storehouse temperature is gone up very big, and these all are unfavorable for food storage; On the other hand, this control method will cause the frequent switch of refrigeration system, reduce the service life of refrigeration plant.The Icetemperature Storage preservation technique is to originate from Japan, it be with food storage in 0 ℃ between the food freezing point, icing warm refrigerating equipment compares with common refrigerating equipment, maximum difference is to ice warm storehouse accuracy of temperature control height, generally require storehouse temperature fluctuation range in ± 0.5 ℃, the chuck technology is mainly adopted in the ice temperature storehouse of Japan, and structure is comparatively complicated, the cost height.
Summary of the invention
The utility model provides a kind of simple in structure, easy to install, ice Wen Ku cooling cycle system that control is stable for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of ice Wen Ku cooling cycle system, comprise refrigeration machine, the condenser that is connected with refrigeration machine, control valve and control instrument, it is characterized in that: this cooling cycle system also comprises heat exchanger, the refrigerating medium feedway, described heat exchanger connects refrigeration machine respectively, condenser and refrigerating medium feedway, described refrigerating medium feedway comprises the refrigerating medium storage bin, the refrigerating medium that is connected with the refrigerating medium storage bin extracts pump, refrigerating medium extracts pump and connects each evaporimeter that is connected in parallel among the ice Wen Ku, on each parallel branch, be equipped with a three-way magnetic valve, three-way magnetic valve is arranged on the input of evaporimeter, the bypass of three-way magnetic valve connects the major loop of the refrigerating medium feedway that is connected with the evaporimeter output, and the major loop of described refrigerating medium feedway connects the refrigerating medium storage bin by heat exchanger.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme: it is the feed flow refrigeration indirectly that the mode that is about to existing direct feed flow refrigeration changes into, cool off refrigerating medium earlier by heat exchanger and grab ethylene glycol solution, thereby be transported to each evaporimeter of ice Wen Ku and the purpose that air carries out heat exchange realization cooling by the refrigerating medium feedway again, on each parallel branch, be provided with a three-way magnetic valve in addition, regulate by three-way magnetic valve, when cold temperature was on a declining curve, the supply opening open degree of feed flow three-way magnetic valve reduced gradually and the bypass amount increases gradually; When cold temperature was in rising trend, the supply opening open degree of feed flow three-way magnetic valve increased gradually and the bypass amount reduces gradually.So be easier to realize the uniform and stable of storehouse temperature than the direct evaporation mode of known cold-producing medium, the utlity model has advantages such as simple in structure, easy to install in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, refrigeration machine; 2, condenser; 3, control valve; 4, control instrument; 5, heat exchanger; 6, refrigerating medium feedway; 6-1, refrigerating medium storage bin; 6-2, refrigerating medium extract pump; 7, evaporimeter; 8, three-way magnetic valve.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of ice Wen Ku cooling cycle system, comprise refrigeration machine 1, the condenser 2 that is connected with refrigeration machine 1, control valve 3 and control instrument 4, heat exchanger 5, refrigerating medium feedway 6, described heat exchanger 5 connects refrigeration machine 1 respectively, condenser 2 and refrigerating medium feedway 6, described refrigerating medium feedway 6 comprises refrigerating medium storage bin 6-1, the refrigerating medium that is connected with refrigerating medium storage bin 6-1 extracts pump 6-2, refrigerating medium extracts pump 6-2 and connects each evaporimeter 7 that is connected in parallel among the ice Wen Ku, on each parallel branch, be equipped with a three-way magnetic valve 8, three-way magnetic valve 8 is arranged on the input of evaporimeter 7, the bypass of three-way magnetic valve 8 connects the major loop of the refrigerating medium feedway 6 that is connected with evaporimeter 7 outputs, and the major loop of described refrigerating medium feedway 6 connects refrigerating medium storage bin 6-1 by heat exchanger 5.
The utility model uses state: when cold temperature was on a declining curve, the supply opening open degree of feed flow three-way magnetic valve reduced gradually and the bypass amount increases gradually; When cold temperature was in rising trend, the supply opening open degree of feed flow three-way magnetic valve increased gradually and the bypass amount reduces gradually. So be easier to realize the uniform and stable of storehouse temperature than the direct evaporation mode of existing cold-producing medium, the utlity model has in addition the advantages such as simple in structure, easy to install.
