Abstract
The invention relates to a refrigerant outdoor-circulation air conditioner. An evaporator is moved outdoors from indoors, an indoor unit is composed of a heat transfer device and a fan, an outdoor unit is formed by a compressor, a four-way valve, a condenser, a fan, an expansion valve, the evaporator and the like in a combined mode, and refrigerant circulates outdoors. A high-efficiency heat transfer pipeline such as a superconductive heat transfer pipeline is adopted for the evaporator and the heat transfer device, and thus high-efficiency heat transfer can be achieved between the outdoor evaporator and the indoor heat transfer device. According to the air conditioner, potential hazards to the human body caused by the situation that the refrigerant may leak indoors are eliminated, and the steam compression type air conditioner is suitable for using refrigerant which does no harm or little harm (ODP is 0, and GWP is 0 or low) to the environment but is flammable and explosive or toxic gas such as hydrocarbon and ammonia.
Description
One, technical field
The present invention relates to a kind of cryogen chamber outer circulation air-conditioning products, be applicable to cold-producing medium and be inflammable, explosive, the family expenses of toxic gas (as hydrocarbon, ammonia etc.), automobile-used, commercial use air conditioner.
Two, background technology
R22 (CHClF
2dichlorodifluoromethane) be the most widely used cold-producing medium of current China air conditioner industry, because R22 has destruction [ODP (ozone-depleting dive value)=0.34] to atmospheric ozone layer, there is global greenhouse effect [GWP (global warming dive value)=1700], European Union has completely forbidden R22 in 2004, the U.S. also no longer produced R22 in 2010, and in developed country, European Union and Japan extensively adopt R410a[R32 (CH
2f
2)/R125 (CHF
2cF
3), 50%/50%], R407c[R32/R125/R134a (CH
2fCF
323%/25%/52%] as cold-producing medium, although the ODP of R410a, R407c is 0, but GWP is respectively 2000,1700, greenhouse effects are serious, so R410a, R407c are transition cold-producing medium, according to requirement in Copenhagen amendment of Montreal Agreement, must use in the year two thousand thirty total ban.China in 2011 only room air conditioner accumulative total produces 13,912 ten thousand, exports 4,363 ten thousand, and therefore the alternative tasks of China R22 is very arduous.
Northern Europe and Germany have started to adopt natural medium hydrogen compound propane (CH
3cH
2cH
3, R290) and as air-conditioning refrigerant, natural medium is as ammonia (NH
3, R717), hydrocarbon is as propane, iso-butane [(CH
3)
2cHCH
3, R600a] and ODP is 0, GWP and is respectively 0,20,20, and environmental sound, is green refrigerant.But because hydrocarbon is fuel gas, ammonia is inflammable, explosive, poisonous gas, as adopt hydrocarbon, ammonia as refrigerant applications in existing air-conditioner, due to existing air-conditioner all adopt cryogen chamber outer-indoor circulation technique, there is cryogen chamber internal leakage hidden danger.Cryogen chamber outer circulation air-conditioning will be eliminated cryogen chamber internal leakage hidden danger, for being widely used of environmental protection cold-producing medium provides condition.
Three, summary of the invention
According to above situation, the object of the invention is to realize cryogen chamber outer circulation, take refrigeration as example, formerly be placed in indoor evaporimeter and move to outdoor, cold-producing medium is through compressor, cross valve, heat transmitter 3 (condenser), through blower fan air inducing, to function of environment heat emission, then expansion valve, heat transmitter 5 (evaporimeter) are realized outdoor circulation.Heat transmitter 5 (evaporimeter) is connected with indoor heat transmitter 6 through efficient heat transfer material, realizes the heat exchange of cold-producing medium and room air.Indoor set is made up of heat transmitter 6 and blower fan, evaporimeter can adopt coil form, indoor heat transmitter 6, heat transmitter 5 all adopt efficient heat transfer material [can adopt superconductive heat transfer pipeline, superconductive heat transfer pipeline is made up of metal and super conducting heat transfer medium that [Granted publication number: CN1238721, Axial Thermal flux is 8.26*10
6w/m
2), the 22nd page, description], super conducting heat transfer medium is the composite of metal oxide, bichromate, monocrystalline silicon, strontium chromate and β-titanium.This superconductive heat transfer pipeline in Dezhou, Shandong Chuan Mao heat energy Science and Technology Ltd. volume production, can customize as requested.
The present invention has four innovations:
1, indoor evaporator is moved to outdoor, make cold-producing medium in outdoor circulation, eliminate inflammable, explosive, poisonous cryogen chamber internal leakage hidden danger.
2, heat transmitter 5 (evaporimeter) is sleeve structure, in sleeve pipe, is refrigerant tubing, refrigerant tubing overcoat superconductive heat transfer pipeline.
3, heat transmitter 5 (evaporimeter) is covered by insulation material, makes heat transmitter 5 (evaporimeter) and outdoor air thermal insulation.
4, heat transmitter 5 (evaporimeter), heat transmitter 6 and between pipeline all adopt superconductive heat transfer pipeline, to realize the efficient heat transfer of indoor heat transmitter and outdoor evaporimeter.
Beneficial effect of the present invention: A/C evaporator is moved to outdoor, adopt efficient heat transfer material, realize the outdoor circulation of air conditioner refrigerant, eliminate cold-producing medium and may reveal potential hazard human body being caused indoor, accelerate to realize the application of the environmental protection such as hydrocarbon, ammonia cold-producing medium in air-conditioner industry.
Four, accompanying drawing explanation as figure be structural principle schematic diagram of the present invention.
In figure 1, compressor 2, cross valve 3, heat transmitter 3,4, expansion valve 5, heat transmitter 56, heat transmitter 6
Five, the specific embodiment
As seen from the figure, indoor set of the present invention is made up of heat transmitter 6, and off-premises station is formed by combining by compressor 1, cross valve 2, heat transmitter 3, expansion valve, heat transmitter 5.
When refrigeration, cross valve DC, ES communicate, cold-producing medium is through compressor 1 cross valve 2 heat transmitters 3 (condensation function), to environmental emission heat, cold-producing medium is through expansion valve 4 heat transmitters 5 (vaporization function), Indoor Thermal air is passed to heat transmitter 5 by heat transmitter 6 through efficient heat transfer material (as superconductive heat transfer pipe), and cold-producing medium is got back to compressor.
While heating, cross valve ED, SC communicate, cold-producing medium is through compressor 1 cross valve 2 heat transmitters 5 (condensation function), heat is through extremely indoor heat transmitter 6 of efficient heat transfer material transfer, cold-producing medium is through expansion valve 4 heat transmitters 3 (vaporization function), absorbing environmental heat, cold-producing medium is got back to compressor.
Between indoor heat transmitter 6 and outdoor heat transmitter 5, superconductive heat transfer number of tubes is by the power determination of air-conditioning, and if power is 1P, coefficient of refrigerating performance is 3.2, and refrigerating capacity is 2352W, as selects φ 20*2.5 metal tube, and pipeline section amasss as 1.37*10
-4m
