Abstract
The invention discloses a refrigerator with a partition of phase change material and relates to the field of refrigerators. The refrigerator comprises a refrigerator body and a cold storage container. A temperature sensor is disposed inside the refrigerator body. A condensing tube is disposed inside the cold storage container. The refrigerator is characterized by further comprising a phase change material partition made by fusing phase change material and plastic, the phase change material partition is disposed between the refrigerator body and the cold storage container, the temperature sensor is electrically connected with the refrigerator body, and the cold storage container is electrically connected with the refrigerator body. The partition of the refrigerator is made of the phase change material, and accordingly, the refrigerator interior container and the food temperature can be kept stable; meanwhile, through nighttime cold storage of the phase change material, nighttime low-cord power is fully utilized, and cold storage cost is reduced greatly.
Description
Technical field
The present invention relates to a kind of refrigerator, specifically a kind of refrigerator that utilizes phase-change material to do interlayer.
Background technology
Along with living standard improves constantly, refrigerator has been widely used in, in a plurality of families, being commonly used to the storage to frozen product.Most frozen product is generally the temperature requirement of storage area: 14 ℃ to-18 ℃, simultaneously, the variation of temperature can have a strong impact on the quality of product.And traditional domestic refrigerator is in the period that the stores food power consumption that need to work without cessation, not only power consumption is relatively many, and, in actual use, always unavoidably regularly refrigerator doors is opened to the taking-up frozen food, can bring moist hot-air into bin when refrigerator doors is opened, thereby cause the variation of temperature in refrigerator, finally causing the temperature of food environment of living in to raise affects the quality of food.Simultaneously, moist hot-air enters in refrigerator can form steam, and these steam can frosting in refrigerator, and refrigerator regularly also needs to carry out the defrosting processing, and this also can make temperature change, and has increased power consumption, has increased cost.The interlayer of existing conventional refrigerator generally adopts heat insulation liquid is annotated to be pressed in plastic interlayer and makes, and such plastic interlayer has the shortcomings such as thickness is high, and heat insulation effect is poor, can't meet the requirement of efficient energy-saving.
For above-mentioned present situation, be bursting to the problem that a kind of refrigerator can solve the food quality caused because of variations in temperature, variations in temperature can be controlled to minimum scope, simultaneously, can solve the power consumption energy consumption issues.
Summary of the invention
The purpose of this invention is to provide a kind of refrigerator that utilizes phase-change material to do interlayer, can solve the problem in the above-mentioned background technology, increase work efficiency, save electric energy, Cost reduction.
In order to solve the problems of the technologies described above, the technical scheme adopted is: a kind of refrigerator that utilizes phase-change material to do interlayer, comprise refrigerator body and cold accumulation container, be provided with temperature sensor in refrigerator body, be provided with condenser pipe in cold accumulation container, it is characterized in that, described refrigerator also contains the phase-change material interlayer, this phase-change material interlayer is merged and is made by phase-change material and plastics, the phase-change material interlayer is arranged between refrigerator body and cold accumulation container, temperature sensor is electrically connected to refrigerator body, and cold accumulation container is electrically connected to refrigerator body.
The invention has the beneficial effects as follows: phase-change material can absorb a large amount of heats in the scope very little in variations in temperature, utilize phase-change material to make the interlayer of refrigerator, maintain to greatest extent the temperature of the interior environment of refrigerator and food a stable value, even, in the process of the in use interior defrosting of switch refrigerator doors or refrigerator and frosting, also the fluctuation of temperature in casing can be controlled to a very little scope.Simultaneously, can pass through the cold-storage at night of phase-change material, take full advantage of the electric power of cheapness at night, play the effect of peak load shifting, thereby reach the purpose of the power cost on a large amount of saving daytime, reduce to greatest extent the refrigeration cost.
The accompanying drawing explanation
Describe in more detail exemplary embodiment of the present invention by the reference accompanying drawing, above and other aspect of the present invention and advantage will become and more be readily clear of, in the accompanying drawings:
Fig. 1 is structured flowchart of the present invention.
The specific embodiment
Hereinafter, now with reference to accompanying drawing, the present invention is described more fully, various embodiment shown in the drawings.Yet the present invention can implement in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, it will be thorough with completely providing these embodiment to make the disclosure, and scope of the present invention is conveyed to those skilled in the art fully.
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
As shown in Figure 1, for structured flowchart of the present invention, a kind of refrigerator that utilizes phase-change material to do interlayer, specifically comprise refrigerator body 1, phase-change material interlayer 2, cold accumulation container 3, be located at the temperature sensor 4 in refrigerator body 1 and be located at the condenser pipe 5 in cold accumulation container 3.Described phase-change material interlayer 2 is arranged between refrigerator body 1 and cold accumulation container 3, connects refrigerator body 1 and cold accumulation container 3, and temperature sensor 4 is electrically connected to refrigerator body 1, and refrigerator body 1 is electrically connected to cold accumulation container 3.Described phase-change material interlayer adopts the eutectic ammonium chloride solution of binary system, and its phase transition temperature is at-15.4 ℃.Described temperature sensor adopts thermocouple, thermistor, resistance temperature detector (RTD) or IC temperature sensor.Described condenser pipe adopts air set pipe, sharp formula condenser pipe, spherical condensation tube or serpentine condenser.
Operation principle of the present invention: when the normal cold-storage of refrigerator, by utilizing the interior cold-producing medium of cold accumulation container 3 and phase-change material interlayer 2 to carry out heat exchange, cold is stored in phase-change material interlayer 2, carrying out heat exchange by the air in phase-change material interlayer 2 and refrigerator body 1 emits the cold of storage, to reach the purpose that maintains low temperature in refrigerator, the temperature on temperature sensor 4 arranges voluntarily according to the user.When the user opens the door of refrigerator, can be by the rapid released cold quantity of phase-change material interlayer 2 after cold-storage to reach refrigeration, to greatest extent the fluctuation of refrigerator body 1 interior temperature is controlled to a very little scope, guarantee the quality of refrigerator body 1 interior food, simultaneously, can pass through phase-change material interlayer cold-storage at 2 night, avoid peak times of power consumption fully, reduce the refrigeration cost of refrigerator.
The foregoing is only embodiments of the invention, be not limited to the present invention.The present invention can have various suitable changes and variation.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
