Abstract
The utility model relates to a double-temperature-range transforming energy-saving refrigerator refrigerating system, which is a circulation loop of refrigerant that comprises a compressor, a condenser, a filter, a capillary tube, and an evaporator. The utility model is characterized in that more than one branch are formed by parallel connection or series-parallel connection of the A-group evaporator and the B-group evaporator in the same room. The branch of B-group evaporator keep open all the time, while two shutoff valves which is arranged in series is positioned at the branch of A-group evaporator, with the function of turning on and turning off. The utility model has two different temperature controlling ranges in according to different condition, the lower temperature will make sure fresh-keeping of standing storage food, while the high temperature will guarantee short term storage of food and have the effect of energy-saving.
Description
Technical field:
The utility model relates to refrigerator refrigeration system, more specifically says so to be made of the refrigerator refrigeration system of refrigerant circulation loop jointly compressor, condenser, filter, capillary and evaporimeter.
Background technology:
At present widespread usage constitutes the refrigerator of refrigerant-cycle systems by compressor, condenser, filter, capillary and evaporimeter, no matter be the household refrigerator-freezer of multi-chamber or household freezer, refrigerating box, refrigerator same chamber adopts single evaporimeter to realize single storage temperature.For example, the refrigerating chamber of household refrigerator-freezer or the same chamber of frozen food storeroom storage temperature only realize " Samsung ", " two stars ", " star " or " soft freezing " one of them, this mode has the following disadvantages: wait and to hang down storage temperature if be designed to " Samsung ", energy-conservation when being unfavorable for only needing the short-term stored food; When being designed to higher storage temperature such as " star ", needing to be unfavorable for the fresh-keeping of longer-term stored food.
Summary of the invention:
Technical problem to be solved in the utility model is to avoid existing deficiency in the above-mentioned prior art, a kind of pair of warm area conversion energy-conserving type refrigerator refrigeration system is provided, this system can be according to user's different requirements, different temperature-control range is set, comprise that the lower temperature of setting is to guarantee the fresh-keeping needs of food long-term storage, and higher relatively temperature is set, under the prerequisite that guarantees food short-term storage, reach energy-conservation effect simultaneously.
The technical scheme that the utility model technical solution problem is adopted is:
The utility model constitutes refrigerant circulation loop by compressor, condenser, filter, capillary and evaporimeter.
Design feature of the present utility model is that the evaporimeter that is in the same chamber constitutes branch road more than one by the A of parallel connection or connection in series-parallel setting group evaporimeter and B group evaporimeter, wherein, B group evaporimeter place branch road is normal open state in described refrigerant circulation loop, in the branch road of described A group evaporimeter, series connection setting has the stop valve of opening and turn-off two controllable state.
Design feature of the present utility model also is before the arrival end of described compressor reservoir to be set.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model can be according to user's different requirements, two different temperature-control range are set, comprise the lower temperature of setting with the fresh-keeping needs of assurance food long-term storage, and higher relatively temperature is set, under the prerequisite that guarantees food short-term storage, reach energy-conservation effect simultaneously.
2, the utility model is simple in structure, easy to implement.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2, Fig. 3 are the different embodiment structural representations of the utility model.
Number in the figure: 1 compressor, 2 condensers, 3 filters, 4 refrigeration evaporators, 5 stop valves, 6 are B group capillary, 10 cascade evaporation devices, 11 reservoirs for B organizes evaporimeter, 8 for A organizes capillary, 9 for A organizes evaporimeter, 7.
Below by the specific embodiment the utility model is further described:
Embodiment:
Referring to Fig. 1, Fig. 2, present embodiment constitutes refrigerant circulation loop by compressor 1, condenser 2, filter 3, capillary and evaporimeter, the evaporimeter that is in the same chamber constitutes branch road more than one by the A of parallel connection or connection in series-parallel setting group evaporimeter 6 and B group evaporimeter 7, wherein, B group evaporimeter 7 place branch roads are normal open state in refrigerant circulation loop, in the branch road of A group evaporimeter 6, series connection setting has the stop valve 5 of opening and turn-off two controllable state.
In order to guarantee that two kinds of duty systems all can move reliably, before the arrival end of compressor 1, be provided with reservoir 11, stop valve 5 is a magnetic valve.
In concrete the enforcement multiple form of implementation can be arranged, in the embodiment as shown in Figure 1, capillary is arranged in each the evaporimeter branch road that sets up separately, before comprising the arrival end that is positioned at A group evaporimeter 6 A group capillary 8 is set, the arrival end that is positioned at B group evaporimeter 7 is provided with B group capillary 9 before, and stop valve 5 is arranged on before the arrival end of A group capillary 8.
Different with scheme shown in Figure 1 is in embodiment shown in Figure 2, to omit B group capillary 9.
Different with scheme shown in Figure 2 is that in embodiment shown in Figure 3, increase is provided with cascade evaporation device 10.
The duty of two warm area conversions:
The lower temperature range duty: stop valve 5 is set is opening, then A group evaporimeter 6 and B group evaporimeter 7 are devoted oneself to work jointly, realize the temperature setting that refrigerating chamber is lower, are used for the needs of lower temperature and long period foodstuff storing.
Relative higher temperature scope duty: stop valve 5 is set is off state, then have only B group evaporimeter 7 to drop in the loops separately and carry out work, realize that the higher relatively temperature of refrigerating chamber sets, can effectively reduce energy consumption satisfying on the basis of food storage.
Claims (2)
1, two warm area conversion energy-conserving type refrigerator refrigeration systems, constitute refrigerant circulation loop by compressor (1), condenser (2), filter (3), capillary and evaporimeter, it is characterized in that being in A group evaporimeter (6) that the evaporimeter in the same chamber is provided with by parallel connection or connection in series-parallel and B group evaporimeter (7) formation more than one branch road, wherein, B group evaporimeter (7) place branch road is normal open state in described refrigerant circulation loop, in the branch road of described A group evaporimeter (6), series connection setting has the stop valve (5) of opening and turn-off two controllable state.
2, refrigerator refrigeration system according to claim 1 is characterized in that being provided with reservoir (11) before the arrival end of described compressor (1).
