The device comprises a compressor, a refrigerator, an evaporator and an expander. An air outlet of the compressor is connected with an air inlet of the refrigerator; the air outlet of the refrigerator is connected with the air inlet of the expander; the air outlet of the expander is connected with an air inlet end of the evaporator; an air outlet end of the evaporator is connected with the air inlet of the compressor; for the whole device, the air can be used as a circulation medium. The utility model can make use of the air as the medium to reduce temperature and pressure so as to reach refrigerating purpose by heat exchange, refrigeration and expansion doing work. Because a reasonable heat circulation system is established, the utility model can be operated. The proposal using air as medium not only can make the medium sources rich and can save cost, but also can not produce environmental pollution and can not produce harmful substances for human body. Thus, the utility model belongs to the ideal product replacing the older generation in the refrigeration industry.
Description
Technical field
The utility model relates to a kind of refrigerating plant, and especially a kind of air expansion type refrigerating plant belongs to the refrigeration facility technical field.
Background technology
Understand according to the applicant, existing refrigeration facility is commonly the vapor-compression formula, and medium adopts ammonia or freon, this type of refrigeration plant or apparatus structure complexity, and cooling is slow, especially has the problem of contaminated environment, health risk.For example, well-known, the ammonia (NH in atmosphere
3) leak when reaching certain index, will cause in various degree the person stimulates, and also can cause poisonings when serious, suffer a shock.
Summary of the invention
The purpose of this utility model is: at the problem that vapor-compression formula refrigeration plant exists, propose a kind of air expansion type refrigerating plant of environmentally safe.
In order to reach above purpose, air expansion type refrigerating plant of the present utility model comprises compressor, cooler, evaporimeter, also comprise decompressor, the gas outlet of described compressor connects the air inlet of cooler, the gas outlet of cooler connects the air inlet of decompressor, the gas outlet of decompressor connects the inlet end of evaporimeter, and the air inlet of the termination compressor of giving vent to anger of evaporimeter, whole device are circulatory mediator (referring to Fig. 1) with the air.
During work, compressor will have certain pressure and temperature under adiabatci condition air is pressed into cooler, then in cooler through cooling and be depressurized near atmospheric pressure, deliver in the expanding chamber cooled compressed air adiabatic expansion in expanding chamber again, pressure further reduces, temperature also drops to below the evaporating temperature, and the air of the back low-pressure low-temperature that expands at last enters evaporimeter, absorbs heat, reach the purpose of refrigeration, return compressor and carry out next one circulation.In brief, the utility model is medium with the air, and through heat exchange cooling expansion working, decrease temperature and pressure reaches the refrigeration purpose.
Because the utility model sets up rational circulation system, therefore practical, and be medium with the air, not only the medium source is abundant, cost economy, and do not pollute the environment, definitely harmless to human body, be the desirable renewal product of refrigeration industry therefore.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the outline drawing of an embodiment of the utility model.
Fig. 3 is the internal structure schematic diagram of Fig. 2 embodiment.
The specific embodiment
Embodiment one
Present embodiment air expansion type refrigerating plant as shown in Figure 3, main building block compressor 1, filter 2, drier 3, cooler 4, decompressor 5, evaporimeter 6 are installed in the cabinet-shaped casing shown in Figure 2 10.Because the gas outlet of compressor 1 connects the air inlet of cooler 4 by 2 and the drier 3 of filter, the gas outlet of cooler 4 connects the air inlet of decompressor 5, the gas outlet of decompressor 5 connects the inlet end of evaporimeter 6, the outlet side of evaporimeter 6 is again to the air inlet that connects compressor 1, form a heating power major cycle system, when therefore working, air dielectric has certain pressure and temperature by compressor 1 under adiabatci condition, through the filtration of filter 2 and dehydrating of drier 3, enter cooler 4; Then cooling and being depressurized in cooler 4 near atmospheric pressure, deliver to again in the expanding chamber 5, cooled compressed air will be in expanding chamber 5 adiabatic expansion, pressure further reduces, temperature also drops to below the evaporating temperature, the back low-pressure low-temperature air that expands at last enters evaporimeter 6, absorbs heat, produces refrigeration.After this, the air of finishing the heat exchange task returns compressor 1 and carries out next one circulation.
In order to regulate the pressure dependence of each link in the major cycle system, make it to meet the required state of refrigeration, the air expansion type refrigerating plant of present embodiment also contains auxilliary circulation line, and this pipeline connects decompressor 4 by the gas outlet of vaporization chamber 6 through auxilliary pressure pipe 7 and constitutes.Like this, can as required the residual air of part vaporization chamber 6 outputs be added in the decompressor 4 of negative pressure by auxilliary pressure pipe 7, reach the purpose of regulating the major cycle system pressure.
The air expansion type refrigerating plant that experiment showed, present embodiment is a medium with the air, does not have any pollution, and the medium source is unrestricted, with low cost.Behind heat exchange cooling expansion working, control expansion ratio well as long as can reach desirable refrigeration purpose, can obtain corresponding temperature drop.No matter from the investment angle, still, all have economy, so popularizing application prospect is good from safeguarding that use angle considers.
