Description
Technical field:
Constant temperature combined refrigerator technology and using method thereof the present invention relates to relent.
Background technology:
Each cold house's temperature of refrigerator is not only to be determined by the evaporating temperature of cold-producing medium in its evaporimeter usually, ratio different that also have cold house's disengagement area (determining refrigerating capacity) and cold house's volume (determining the thermic load amount), also participate in determining the temperature of each cold house to a large extent, therefore, the same evaporating temperature of cold-producing medium in evaporimeter can be determined different cold house's serviceability temperatures, and cryogenic freezing chamber and the refrigerating capacity in the high temperature refrigerating chamber in the current refrigerator are exactly the cold-producing medium that comes from same evaporating temperature.For this reason, the refrigerating chamber of current refrigerator and refrigerating chamber all are constant temperatures, that is: the refrigerating chamber of low temperature can not become the refrigerating chamber of high temperature, otherwise also not all right.Yet the prior art temperature controller stops and the time ratio row of opening by the control compressor, can finely tune the temperature of each cold house in certain temperature range, still, and the interval of absolutely not change refrigerating chamber of this fine tune temperature or the basic serviceability temperature of refrigerating chamber.
If, a refrigerator has been provided with indispensable refrigerating chamber and refrigerating chamber in the use, set up an alternating temperature cold house on this basis again, in case of necessity, its temperature can either be turned down and to be used as the degree that (when buying the freezing meat product of too much needs) used in the cryogenic freezing chamber, its temperature can be heightened the degree of using (when buying too much beverage or fresh vegetables) as refrigerating chamber again, this certainly will expand the function of use of refrigerator to a great extent.And, so set up the refrigerator of alternating temperature cold house, if can accomplish again: simple in structure, reliable in quality, with low cost, easy and simple to handle, just can in the refrigerator series of products, occupy one seat, be that the user brings convenience with its high practicability.
It is to be noted: the evaporimeter in evaporimeter in the alternating temperature cold house and the constant temperature cold house can not be parallel in the refrigeration system and work, this be because: when the evaporating temperature of cold-producing medium evaporimeter in the alternating temperature cold house changes, the work compression ratio of compressor two ends also can change thereupon, and alters a great deal; And the evaporating temperature of cold-producing medium evaporimeter in the constant temperature cold house is constant substantially, thereby requires the work compression ratio of compressor two ends also can not become substantially.If a compressor is worked in two refrigeration systems of constant temperature that relent of parallel connection, will force compressor balance on the work compression ratio of a compromise, to alternating temperature cold house and constant temperature cold house the two cold-producing medium evaporation operating temperature to pin down influence mutually very big, be difficult to set up the serviceability temperature of needed each cold house according to relevant refrigerator standard.
Summary of the invention:
The present invention's purpose: be provided with at current refrigerator on the general layout basis of constant temperature cold houses such as refrigerating chamber and refrigerating chamber, propose to set up again the design of a kind of alternating temperature cold house in order to improve its practicality.
In order to realize the present invention's purpose, intend adopting following technology:
One. be provided with at least one constant temperature cold house, the refrigeration system at its constant temperature evaporimeter place is independently;
Two. also be provided with the alternating temperature cold house, another refrigeration system at its alternating temperature special evaporator place also is independently, and the alternating temperature key technology that is adopted is: the throttling flow resistance of a. by full seal type solenoid control serial or parallel connection capillary restrictor changes and realizes; Perhaps: the commutation of b. by the full seal type two position three way directional control valve, utilize the capillary restrictor of different flow resistances to realize;
Three. consist of one with dismountable version between alternating temperature cold house and the constant temperature cold house, or consist of one with non-removable version.
Four. constant temperature cold house temperature adjusting (actual serviceability temperature) method of supporting by evaporimeter in the refrigeration system independently: by temperature controller fine setting (time of stopping of control compressor) to needed actual serviceability temperature.
Five. the Guan Yukai that also has alternating temperature cold house temperature adjusting (actual serviceability temperature) method: a. that is supported by evaporimeter in another self-contained refrigerating system at first to pass through the full seal type magnetic valve controls the evaporating temperature of cold-producing medium in the alternating temperature special evaporator, and then finely tunes (time of stopping of control compressor) to needed actual serviceability temperature by temperature controller; Perhaps: b. at first controls the evaporating temperature of cold-producing medium in the alternating temperature special evaporator by the commutation of full seal type two position three way directional control valve, and then finely tunes (time of stopping of control compressor) to needed actual serviceability temperature by temperature controller.The needed actual serviceability temperature in chamber.
Characteristics of the present invention: simple in structure, reliable in quality, with low cost, easy to operate, the old and the young all easily grasp use.

The specific embodiment:
By the vertical refrigerator embodiment of Fig. 1 signal, being actually fully can separate existence by two: the two constant temperature refrigerators in two Room that belong to prior art that are positioned at the single chamber alternating temperature refrigerator of top and are positioned at the below are formed.
By desk-type refrigerator (top can be used as galley dresser and the uses) embodiment of Fig. 2 signal, be difunctional (refrigerator and furniture are dual-purpose) and the special formed integrated form refrigerator of tool that three cold house can not be separate.
Be not difficult to find from the signal of Fig. 1 and Fig. 2: the compressor that adopts among each embodiment (3) all is two.
Here it is to be noted: two compressors of this among the present invention (3) can not be present in the refrigeration system in parallel connection, but are present in respectively among two separate refrigeration systems.---as long as contain alternating temperature cold house (B) in the refrigerator, so, the refrigeration system at alternating temperature special evaporator (1) place in this cold house must be independently, can not merge with other refrigeration system to use.Because, variations in temperature in the alternating temperature cold house (B), be to change into leading with the evaporating temperature of cold-producing medium in alternating temperature special evaporator (1), the work compression ratio of compressor when temperature becomes (3) alters a great deal, if alternating temperature special evaporator (1) coexists with refrigerating evaporator (5) and refrigeration evaporator (6) in the refrigeration system, the influence that pins down mutually on evaporating temperature will be very big, finally will have a strong impact on the operating temperature of each cold house.
Below in conjunction with the accompanying drawings valve control alternating temperature principle crucial among the present invention is illustrated again:
One. by shown in Figure 3, first capillary restrictor (7) and second capillary restrictor (8) series connection are used, and magnetic valve (9) and wherein second capillary restrictor (8) use in parallel, obviously:
When magnetic valve (9) when closing, the throttling flow resistance maximum that series connection forms, cold-producing medium is in the cryogenic refrigeration evaporating state in alternating temperature special evaporator (1); When magnetic valve (9) was opened, second capillary restrictor (8) was by short circuit, and only remaining first capillary restrictor (7) works, and the throttling flow resistance diminishes, and cold-producing medium is in high temperature refrigeration evaporator state in alternating temperature special evaporator (1).
Two. by shown in Figure 4, first capillary restrictor (7) and second capillary restrictor (8) are in parallel to be used, and magnetic valve (9) links to each other above-mentioned the two at same end, obviously:
When magnetic valve (9) when closing, second capillary restrictor (8) is blocked, and only remaining first capillary restrictor (7) works, the throttling flow resistance maximum of this moment, and cold-producing medium is in the cryogenic refrigeration evaporating state in alternating temperature special evaporator (1); When magnetic valve (9) was opened, second capillary restrictor (8) in parallel also worked simultaneously, and the throttling flow resistance under the state in parallel diminishes, and cold-producing medium is in high temperature refrigeration evaporator state in alternating temperature special evaporator (1).
Three. by shown in Figure 5, first capillary restrictor (7) and second capillary restrictor (8) are still in parallel to be used, just select one of above-mentioned the two for use by two position three way directional control valve (10), when two position three way directional control valve (10) is selected first capillary restrictor (7) of high flow resistance for use, cold-producing medium is in the cryogenic refrigeration evaporating state in alternating temperature special evaporator (1), when two position three way directional control valve (10) was selected second capillary restrictor (8) of low flow resistance for use, cold-producing medium was in high temperature refrigeration evaporator state in alternating temperature special evaporator (1).
From refrigeration principle, allowing same refrigeration system be in different cooling condition (alternating temperature) is that part is easy to it Thing as long as the throttling flow resistance that changes in the refrigeration system can realize, but during for concrete product design, be accomplished Good and cheap but the act easily just can be accomplished: key of the present invention is the purpose that realizes that it is good and cheap.
