Abstract
The refrigerator without the refrigerating system and disusing the refrigerant uses the operating principle of slow oxidation and corrosion resisting of the material on conditon that the content of oxygen-like active gases is lower to store the materials. When the concentration of the oxygen-like active gases in the storeroom of the inventive refrigerator exceeds the warning value, the gas concentration detecting controller will start to work. An internal circulating separator removes the oxygen-like active gases in the storeroom under the action of pressure difference produced in the gas compressor and then leads the rest inert gas to the storeroom of the said refrigerator, so that an external circulating system starts to work.
Description
Technical field the present invention relates to a kind of without cold-producing medium or there be not " refrigerator " of refrigeration system.The not only energy-conservation but also environmental protection fully of the use of this " refrigerator " is widely used in the storage of various materials, and is fresh-keeping etc.
Background technology is present, and known refrigerator is the applied material principle that oxidation is slow or corrosion resistant is mashed at low temperatures, and application cold-producing medium or refrigeration system are finished.And domestic used cold-producing medium not only can damage the ozone layer, and also can produce serious greenhouse effects, even the current cold-producing medium of environmental protection in the world also can produce greenhouse effects.National government such as America and Europe are very strict to the use standard-required of cold-producing medium, and China has added the two worlds pact in this field at present, and prepare in several years of future progressively to forbid in China and contain fluorinated refrigerant.Simultaneously present refrigerator needs work that very high pressure carries out refrigeration system, so its compressor must have very high power, wastes so very much electric power resource.And cryopreservation has certain destruction to the nutritive value of material.Hence one can see that, and the birth of a kind of not only fully environmental protection but also energy-conservation refrigerator will be a revolution in refrigerator field.And up to the present, real such refrigerator does not also emerge.
Summary of the invention is in order to solve problem recited above fully, the invention provides a kind of without cold-producing medium or there be not " refrigerator " of refrigeration system.It is the applied material principle that oxidation is slow or corrosion resistant is mashed at low temperatures that the present invention has abandoned known refrigerator, but applied material is in the environment that does not have oxygen isoreactivity gas or the principle that oxidation is slow or corrosion resistant is mashed in the lower environment of oxygen isoreactivity gas content, adopt inside and outside two circulation air-channel system, use low pressure gas compressor (having only several kilograms of pressure), by gas separator the oxygen isoreactivity gas in " refrigerator " is removed, import remaining inert gas (mainly being nitrogen) in the storeroom of " refrigerator " once more then, thereby to the long-term preservation of materials such as food of " refrigerator " lining, external circulating system begins internal circulation system is carried out the inert gas compensation simultaneously.This " refrigerator " without any destruction, saves electric power to environment, almost do not have noise, storage and fresh-keeping effective.
The present invention will be further described below in conjunction with accompanying drawing (side view) for description of drawings.Earlier the numbering among the figure is carried out as directed: 1. storeroom 5. outer circulation gas separators 6. outer circulation conduits 7. gas concentrations of recyclegas separator 3. interior circulation conduits 4. " refrigerator " detect controller in the gas compressor 2..Wherein interior recyclegas separator (2) can adopt film to separate with outer circulation gas separator (5) or gas separation such as molecular sieve.See figure, people can bring airborne oxygen isoreactivity gas in the life when the storeroom (4) of " refrigerator " picks and places materials such as food fruit, when the concentration of the oxygen isoreactivity gas in the storeroom (4) surpasses warning value, internal circulation system has just been started working, the gas concentration of this moment detects controller (7) with driving gas compressor (1), see the small arrow direction, the portion gas boil down to gases at high pressure of storeroom (4) lining, thereby the both sides of recyclegas separator (2) generation gas has only several kilograms pressure differential in making.Interior recyclegas separator (2) begins gas separation process under action of pressure, oxygen isoreactivity gas in the gases at high pressure discharged or store to stay use it for anything else, remaining inert gases such as nitrogen mainly are nitrogen, are imported into storeroom (4) through interior circulation conduit (3).At this moment, external circulating system brings into operation, internal circulation system is carried out the gas compensation, see the big direction of arrow, extraneous atmospheric air becomes pressure-air after gas compressor (1) compression, outer circulation gas separator (5) begins gas separation process under the effect of pressure at both sides difference, oxygen isoreactivity gas in the pressure-air is discharged, and remaining inert gas is imported into storeroom (4) through outer circulation conduit (6), like this, material such as food just can be stored or fresh-keeping in storeroom (3).
Specific embodiment the present invention implements in the following way: what the storeroom of " refrigerator " (4) bottom and side lower part were installed respectively is interior recyclegas separator (2), gas compressor (1), outer circulation gas separator (5), gas concentration detects controller (7).Wherein gas compressor (1) should be selected the compressor of low-power low-pressure for use, does simple processing and gets final product.The density of considering oxygen is greater than nitrogen, so the outlet of interior circulation conduit (3) and outer circulation gas conduit (6) is installed in the first half of " refrigerator " storeroom (4).When the concentration of the oxygen isoreactivity gas in the storeroom (4) surpasses warning value, the internal circulation system system has just started working, the gas concentration of this moment detects controller (7) with driving gas compressor (1), the portion gas boil down to gases at high pressure of storeroom (4) lining, thereby the both sides of recyclegas separator (2) produce gas pressure difference in making.Interior recyclegas separator (2) begins gas separation process under action of pressure, the oxygen isoreactivity gas in the gases at high pressure is discharged, and remaining inert gases such as nitrogen are imported into storeroom (4) through interior circulation conduit (3).At this moment, external circulating system brings into operation, internal circulation system is carried out the gas compensation, extraneous atmospheric air becomes pressure-air after gas compressor (1) compression, outer circulation gas separator (5) begins gas separation process under the effect of pressure at both sides difference, the oxygen isoreactivity gas in the pressure-air is discharged or stored to stay use it for anything else remaining inert gases such as nitrogen, be imported into storeroom (4) through outer circulation conduit (6), finished inert gas compensation internal circulation system.In actual production was manufactured, (3) and (6) placed the inside of " refrigerator " more attractive in appearance, can be (2) and (5), and (3) and (6) are reduced to one.
