Description
Technical field
The utility model relates to refrigerator technical field, in particular to a kind of refrigerator refrigeration system, and has the refrigerator of this refrigerator refrigeration system.
Background technology
For two refrigerators, refrigeration system many employings single capillary structure, capillary and refrigerating evaporator and refrigeration evaporator are connected in series, only there is a relatively-stationary pressure reduction in whole refrigeration system, thus when changing temperature on an equal basis, the evaporating temperature of whole refrigeration system is relatively-stationary, and all from same capillary, that is the evaporating temperature of refrigerating evaporator and refrigeration evaporator is more or less the same.And in fact temperature of refrigerating chamber remains on more than 0 DEG C, the temperature of refrigerating chamber will remain on subzero tens degree, and different temperature range adopts identical lower evaporating temperature, and concerning the total pressure head increasing system refrigerator, energy consumption is comparatively large, causes damage.
Utility model content
The utility model is the weak point for avoiding existing for above-mentioned prior art, a kind of refrigerator refrigeration system with double capillary is provided and uses the refrigerator of this refrigeration system, to the mode by employing two capillary series connection, improve the evaporating pressure of refrigerating chamber and refrigerating chamber, reduce the vapor pressure deficit of refrigerating chamber and refrigerating chamber, promote the refrigerating efficiency of refrigerator, reduce energy consumption of refrigerator.
The utility model technical solution problem adopts following technical scheme:
The utility model is with the refrigerator refrigeration system of double capillary, and its design feature is: described refrigerator refrigeration system comprises the compressor, the first condenser, anti-condensation pipes, the second condenser, filter, refrigeration evaporator capillary, refrigeration evaporator, refrigerating evaporator capillary and the refrigerating evaporator that are linked in sequence successively; The entrance of described first condenser is connected with the outlet of described compressor, and the outlet of described refrigerating evaporator is connected with the entrance of described compressor.
The invention also discloses the refrigerator using this refrigeration system, comprise casing, its design feature is: have refrigerating chamber, refrigerating chamber and refrigeration system in described casing, described refrigeration system adopts the disclosed refrigerator refrigeration system with double capillary of the utility model, the refrigeration evaporator of wherein said refrigerator refrigeration system is used for freezing to described refrigerating chamber, and refrigerating evaporator is used for freezing to described refrigerating chamber.
The utility model adopts the mode of two capillary series connection, i.e. capillary second throttle technology.Be specially cold-producing medium from compressor to condenser and after device for drying and filtering, enter refrigeration evaporator by refrigeration evaporator capillary, then enter refrigerating evaporator by refrigerating evaporator capillary and finally get back to compressor, circulate and so forth.
The utility model arranges two capillaries in refrigerator refrigeration system, one of them is as refrigeration evaporator capillary, the pressure reduction of this capillary is less than the pressure reduction of the single capillary that conventional system adopts, and can produce the slightly high evaporating temperature of relatively single capillary like this.Produce identical cold in order to ensure refrigerating chamber at same time, the utility model refrigerates the method for heat transfer pipe to promote refrigerating efficiency by the disengagement area and growth increasing refrigeration evaporator simultaneously.Compared with the single capillary of routine, the large pressure reduction of refrigeration evaporator capillary flow rate that the utility model adopts is little, relative energy-saving.Another capillary is as refrigerating evaporator capillary, connect refrigeration evaporator and refrigerating evaporator, lower relative to the refrigerant temperature of condenser from refrigeration evaporator refrigerant temperature out, pressure is less, therefore adopt flow is comparatively large, pressure reduction is less refrigerating evaporator capillary that refrigeration evaporator refrigerant temperature out just can be made to be reduced to evaporating temperature required for refrigerating evaporator, reduce system pressure difference and system loss, thus reach energy-conservation object.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Refrigeration system of the present utility model adopts the mode of two capillary series connection, refrigeration evaporator capillary all improves flow compared with the single capillary system of refrigerating evaporator capillary and tradition, reduce respective pressure reduction, refrigeration evaporator area strengthens and improves refrigerating efficiency, by the adjustment of two capillary pressuring differences, reduce system pressure difference and system loss, achieve the efficient and rational distribution of refrigerator cold, reduce power consumption.

Specific embodiment
Below by way of detailed description of the invention, and the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, the present embodiment comprises with the refrigerator refrigeration system of double capillary compressor 9, first condenser 1, anti-condensation pipes 2, second condenser 3, filter 4, refrigeration evaporator capillary 5, refrigeration evaporator 6, refrigerating evaporator capillary 7 and the refrigerating evaporator 8 that are linked in sequence successively; The entrance of the first condenser 1 is connected with the outlet of compressor 9, and the outlet of refrigerating evaporator 8 is connected with the entrance of compressor 9.During use, cold-producing medium flows through compressor 9, first condenser 1 successively, anti-condensation pipes 2, second condenser 3, filter 4, then refrigeration evaporator 6 is entered by refrigeration evaporator capillary 5, enter refrigerating evaporator 8 by refrigerating evaporator capillary 7 again and finally get back to compressor 9, circulate and so forth.
As shown in Figures 2 and 3, above-mentioned refrigerator refrigeration system is used in refrigerator by the present embodiment, is arranged in refrigerator body, and the refrigeration evaporator 6 of refrigerator refrigeration system is for freezing to refrigerating chamber, and refrigerating evaporator 8 is for freezing to refrigerating chamber.Cold-producing medium first enters refrigeration evaporator by refrigeration evaporator capillary, freezes to refrigerating chamber; Then enter refrigerating evaporator by refrigerating evaporator capillary, refrigerating chamber is freezed.
