Abstract
The invention discloses a household zero-consumption refrigerating unit comprising a liquefied gas tank which stores liquefied gas, a liquefied gas stove and a refrigerating box. A metal capillary tube and an evaporating tube are disposed inside the refrigerating box. The inner diameter of the evaporating tube is larger than that of the metal capillary tube. The evaporating tube is disposed around the inner wall of the refrigerating box and used for absorbing heat. One end of the metal capillary tube is connected with the evaporating tube. The other end of the metal capillary tube is connected with the output end of the liquefied gas tank through a compressive insulation tube. The output end of the evaporating tube is connected with the input end of the liquefied gas stove. The household zero-consumption refrigerating unit is designed with the liquefied gas and liquefied natural gas stove for daily use, is simple in structure and convenient to use with zero consumption, is available for cold storage and preservation of foods, and has good practical value.
Description
?
Technical field
The present invention relates to a kind of refrigeration plant, relate in particular to a kind of domestic zero and consume refrigerating plant.
Background technology
Refrigeration is refrigeration, claims again freezingly, and object temperature is reduced to or is maintained below natural environment temperature.The approach that realizes refrigeration has two kinds, and the one, natural cooling, the one, artificial cooling.Naturally coolingly utilize natural ice or phreatic water cooling object, but its refrigerating capacity (heat of taking away from the object that is cooled) and the cryogenic temperature that may reach often can not meet need of production.Natural cooling be a diabatic process.Artificial cooling is to utilize refrigeration plant to add energy, a kind of unit operations that belongs to thermodynamic process that heat is shifted from cryogenic object to high temp objects.Existing artificial cooling equipment price is expensive, complex structure, and need to consume a large amount of energy.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of domestic zero to consume refrigerating plant, this refrigerating plant utilizes existing liquefied gas, liquefied natural gas kitchen range and refrigeration case to make, and it is simple in structure, easy to use, Non-energy-consumption, can refrigerate with fresh-keeping food, has good practical value.
Technical scheme: a kind of domestic zero of the present invention consumes refrigerating plant, comprise the liquid gas storage tank, LPG range and the refrigeration case that contain liquefied gas, in described refrigeration case, be provided with metal capillary and evaporation tube, the internal diameter of described evaporation tube is greater than the internal diameter of metal capillary, described evaporation tube is arranged on the surrounding of refrigeration case inwall, be used for absorbing heat, one end of described metal capillary is connected with evaporation tube, the other end is connected with the output of liquid gas storage tank by resistance to compression instlated tubular, and the output of described evaporation tube is connected with the input of LPG range.
Further, described refrigeration case consists of inner housing and shell body, between described inner housing and shell body, is filled with heat preserving and insulating material.
Further improve technique scheme, described refrigeration case is provided with electronic thermometer, described electronic thermometer comprises temperature sensor, single-chip microcomputer and display screen, described temperature sensor is arranged in refrigeration case, described display screen is arranged on the sidewall of refrigeration case, described temperature sensor is connected with single-chip microcomputer, and described single-chip microcomputer is connected with display screen.
Further, be also provided with humidity sensor in described refrigeration case, described humidity sensor is connected with single-chip microcomputer.
The present most of family of above-mentioned refrigerating plant utilization is used liquefaction day hot gas range, and its liquefied gas is by after compression, is stored in gas tank, then by relief cock with gaseous form out with liquid form.Liquid state becomes in the process of gaseous state need to absorb heat from the external world.Refrigeration case utilizes liquid state to become gaseous state need to absorb heat and complete refrigeration just.
First liquid gas storage tank butt joint is connected with metal capillary with resistance to compression instlated tubular, access again evaporation tube, when liquid combustion gas enters evaporation tube by capillary, due to the internal diameter of evaporation tube than internal diameter capillaceous large tens times, liquid combustion gas has obtained abundant space and has expanded and vaporize, make liquid combustion gas provide gas liquefaction required heat from a large amount of heat of refrigeration case absorbed inside, thereby reach the object of cooling.Combustion gas after vaporization enters gas-cooker burning through appendix, completes the daily heating process of liquefied gas.
Compared with prior art, its beneficial effect is in the present invention: the present invention utilizes family's liquefied gas used in everyday, liquefied natural gas kitchen range to design, and it is simple in structure, easy to use, and Non-energy-consumption can refrigerate with fresh-keeping food, has good practical value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
