Abstract
The present invention relates to a single chamber temperature variable refrigerator with parallel type throttle valves and a use method thereof. At least one set of second capillary current regulators (8) are connected to an original capillary current regulator (7) of a refrigerator refrigerating system in parallel, and the same ends of the adjacent regulators connected in parallel are connected by an electromagnetic control type cut-off valve (6) fully sealed. The temperature of refrigerant in an evaporator (3) of a single refrigerating chamber can be changed through conveniently closing and opening the cut-off valve (6), namely selecting low temperature refrigerating temperature for frozen food or high temperature refrigerating temperature for refrigerated food(storing fresh food).
Description
Technical field:
The present invention relates to simple type refrigerator refrigeration grade an alternating temperature technology and a using method thereof are arranged.
Background technology:
The refrigerating chamber of 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.If the cold house of a refrigerator where necessary, its temperature can either be turned down and be used as the cryogenic freezing chamber and use (when buying the freezing meat product of many needs), its temperature can be heightened again as refrigerating chamber and use (when buying many beverages or fresh vegetables), and, the refrigerator of variable temperature like this, if can accomplish again: simple in structure, reliable in quality, with low cost, just can in the refrigerator series of products, occupy one seat.
Summary of the invention:
The present invention's purpose: propose a kind of by in refrigerator refrigeration system, adopting the version of choke valve in parallel to come the control method of its refrigeration evaporator temperature of conversion to solve the problems referred to above.
In order to realize the present invention's purpose, intend adopting following technology:
On the structure: its refrigeration system comprises on the basis of evaporimeter, condenser, compressor and first throttle device main part at least, in above-mentioned refrigeration system the first throttle device other in parallel at least one group by second flow controller and the two additional throttling arrangement that is in series mutually of stop valve.This stop valve adopts totally-enclosed type (detachable position is all covered sealing by metal welding) electromagnetic control type.
In order to satisfy the requirement of refrigerator single chamber alternating temperature, compressor among the present invention should adopt low back pressure type, yet its rated power, and the heat exchange area of evaporimeter and condenser, but should design definite according to the specification requirement of the high temperature cooling condition (forming the refrigerating chamber of above-mentioned maximum temperature) of refrigerating capacity maximum (compressor operating compression ratio minimum).
Using method: when using the cryogenic refrigeration operating mode, with above-mentioned stop valve Close All; When using high temperature (can establish various temperature) cooling condition, at least one stop valve among the above-mentioned person in parallel opened.
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.
Description of drawings:
Figure has illustrated simple embodiment of the present invention: the two alternating temperature refrigerators of single chamber.
1: the refrigerator thermal insulating door thermally insulated door; 2: the refrigerator insulation shell; 3: evaporimeter; 4: heat exchanger; 5: condenser; 6: the full seal type electromagnet cut off valve; 7: the first capillary restrictors; 8: the second capillary restrictors; 9: device for drying and filtering; 10: compressor.
The specific embodiment:
First capillary restrictor, 7 independent adapteds are in refrigerator refrigeration system, and controlled cold-producing medium is in low-temperature evaporation state (about 30 ℃) in system evaporimeter 3, make refrigerator become refrigerating chamber (18～-24 ℃).
When second capillary restrictor 8 is in parallel with first capillary restrictor 8, flow resistance reduces, in refrigerator refrigeration system, controlled cold-producing medium is in high temperature evaporation state (about 2 ℃) in system evaporimeter 3, make refrigerator become refrigerating chamber (10～15 ℃) with its two adapted.
When refrigerator is desired to use as cryogenic freezing case (chamber): get final product by the automatically controlled stop valve 6 of closing.
------first capillary restrictor 7 works and second capillary restrictor 8 is inoperative, at high flow resistance throttle, allow the work compression ratio of compressor 10 raise, the evaporating temperature of refrigeration system is controlled at about-30 ℃, temperature controller is also transferred the files and is assisted the fine setting temperature control by control compressor 10 start-stops between-18～-24 ℃.
When refrigerator is desired to use as high temperature refrigerating box (chamber): get final product by automatically controlled unlatching stop valve 6.
------second capillary restrictor 8 works, it is with after first capillary restrictor 7 is in parallel, form low flow resistance throttle, allow the work compression ratio of compressor 10 reduce, the evaporating temperature of refrigeration system is controlled at about 2 ℃, and temperature controller is also transferred the files and is assisted the fine setting temperature control by control compressor 10 start-stops between 10～15 ℃.
