Abstract
The utility model relates to a cold-storage energy-saving refrigerator and is characterized in that the evaporating pipe arranged inside a refrigerator wall is provided with a pipelaying cold-storage plate with the intracavity filled with cold-storage working substance; meanwhile, the internal wall of the refrigerator is also packaged with a refrigerator wall cold-storage veneer with the intracavity filled with cold-storage working substance. The utility model realizes practical application of cold-storage energy-saving technology in refrigerator and greatly reduces start frequency of refrigerator without influencing the temperature inside refrigerator, thereby obtaining energy-saving effect.
Description
The utility model relates to a kind of refrigerator and stores cold power-saving technology.
The operation of general refrigerator, its unit start and stop frequency is big more, and its idle work consumption is big more, can realize energy-conservation by the start and stop frequency that reduces the refrigerator unit.The energy-saving and frequency-variable technology has appearred for this reason.The such small-power household electrical appliances employing frequency conversion of refrigerator can be energy-conservation, its essence during except underload motor still keep the high efficiency, mainly be unit according to variation of ambient temperature adjustment load, unit can be moved continuously, overcome the start-stop excess power loss that stops causing continually of general refrigerator unit.But frequency changer is formed originally higher, and its application on low power refrigerator household electrical appliances is limited to.The cold that uses the cold working medium absorbent refrigeration system of storage to emit, and when system-down, cold is emitted, can under the situation that does not influence temperature in the refrigerator, reduce refrigerator start and stop frequency, reach purpose of energy saving.But use at present the cold power-saving technology of above-mentioned storage on refrigerator, only limit to place one or two storage cold drawing in refrigerator, because the storage cold drawing is arbitrarily put, its energy-saving effect is extremely low.
The purpose of this utility model is to propose a kind of utilization storage refrigeration technique, and cost is low and Remarkable Energy Saving is store cold energy-saving refrigerator.The utility model is fully to use the cold energy-saving principle of storage, order about refrigeration working medium by compressor and flow through the evaporation tube evaporation and emit the refrigerator structure of cold and transform existing, in the structure of refrigerator, the refrigerating chamber and the refrigerating chamber that comprise refrigerator, its refrigerator wall interior (comprising indoor interlayer) is equipped with evaporation tube, be characterized in laying the tubine storage cold drawing that its inner chamber is filled with the cold working medium of storage at said evaporation tube place, said tubine storage cold drawing is close on the evaporation tube.
For increasing the contact-making surface between thin type storage cold drawing and the evaporation tube, the one side of said tubine storage cold drawing contact evaporation tube can be formed the groove that pastes mutually with evaporation tube.
Said tubine storage cold drawing can adopt high heat-conducting plastic to make, and its suitable gross thickness is 8～10mm, and wall thickness is 0.5～1mm.
For increasing storage cold energy power, improve the cold energy-saving effect of storage, further scheme of the present utility model is to be set forth on the basis of laying tubine storage cold drawing in the evaporation tube place last, (comprises refrigerating chamber and refrigerating chamber) and encapsulate the tank wall cold-storing layer plate formation tank wall cold-storing layer that its inner chamber is filled with the cold working medium of storage again around the inwall of refrigerator.
Said tank wall cold-storing layer plate can adopt high heat-conducting plastic to make, and its suitable depth is 4～5mm, and wall thickness is 0.5～1mm.
The cold working medium of storage of being filled in said tubine storage cold drawing and the tank wall cold-storing layer plate chamber can adopt various existing high storage cryogen working materials, only require that generally the freezing point of used storage cryogen material and the evaporating temperature of refrigerator adapt, for refrigerating chamber, it is-16～-20 ℃ storage cryogen that said tubine storage cold drawing inner chamber can fill freezing point, and it is 0～2 ℃ storage cryogen that said tank wall cold-storing layer plate inner chamber can fill freezing point; For refrigerating chamber, it is-24～-28 ℃ storage cryogen that said tubine storage cold drawing inner chamber can fill freezing point, and it is-19～-23 ℃ storage cryogen that said tank wall cold-storing layer plate inner chamber can fill freezing point.
The utility model makes the cold power-saving technology of storage obtain the application of essence in refrigerator.Under the situation that does not influence the refrigerator indoor temperature, significantly reduce refrigerator start and stop frequency, realize energy-conservation effect.Simultaneously the cryogen evaporating temperature of refrigerator is stabilized on the higher temperature levels, according to the kind of refrigeration cycle thermodynamic property, under the constant situation of high-pressure side cryogen condensation temperature, it is well-known that the evaporating temperature of raising low-pressure end can make cycle efficieny improve, but therefore cool storing refrigeratory a little improve cryogen evaporating temperature, this point also has a contribution to energy-conservation.The utility model our experiments show that, can save energy 5～13%.Except that energy-conservation, the utility model also can be realized refrigerator start at night refrigeration, and shut down daytime, puts the cold low temperature of keeping by the storage cryogen.China has carried out the electricity bill control system of encouraging (during the electric load low ebb) electricity consumption at night in most of city, and the general electricity charge at night unit price has only 1/2nd of daytime, and therefore the cold energy-saving refrigerator of storage of the present utility model can reduce operating cost significantly.Because cost of the present utility model is lower, has broad application prospects.
Accompanying drawing is store the structure chart of cold energy-saving refrigerator embodiment for this;
