Description
Technical field
The invention belongs to refrigerant technology field, more particularly to a kind of it is applied to substitute R410A's in air-conditioning/heat pump
Mix refrigerant.
Background technology
Depletion of the ozone layer and global warming are two big main environmental problems of mankind nowadays society facing.In order to answer
The harm brought to the two environmental problems, international community successively work out and endorsed《Vienna Convention》、《Discuss and decide in Montreal
Book》、《The United Nations's climate change framework treaty》With《The Kyoto Protocol》Etc. a series of international conventioies.What part of in September, 2007 was held
In the 19th conference of contracting party of Montreal Protocol, international community has further reached the adjustment case for accelerating to eliminate HCFCs,
Adjustment cut down 10% with output by the HCFCs consumption figures for defining developing country by 2015, and 35% is cut down to the year two thousand twenty,
67.5% was cut down by 2025, is all eliminated completely to the year two thousand thirty, but allows between 2030-2040 to retain average annual 2.5% and supplies
Maintenance is used.Chinese Government pay much attention to reply climate change problem, 2009 shortly before the climate Conference of Copenhagen, Chinese Government
Announce, the CO2 emission levels of per GDP 40%~45% will be reduced compared to 2005 to the year two thousand twenty.Chinese Government
The policy, regulation and programme of a series of State-levels have been formulated, including《China's reply climate change national scheme》、《State
Family's acclimatization change strategy》、《Country's reply climate change planning (2014-2020)》、《2014-2015 energy-saving and emission-reduction
Low-carbon action scheme》Deng.R410A is once considered as substituting the optimal refrigerants of R22, but its GWP is higher, is 2100, even
Higher than the 1810 of R22, R410A no longer turns into preferable alternative refrigerant under the overall situation of current low-carbon environment-friendly, therefore seeks
It is the severe challenge faced at present to look for novel environment-friendly refrigerant to substitute R410A.
In existing refrigerant patented technology, patent CN 1087107A disclose what is be made up of difluoromethane and propane
Mix refrigerant；The A of patent CN 101775268 disclose a kind of by difluoromethane and the mixture of propylene；Patent JP
11230626 disclose the mix refrigerant formed with difluoromethane and iso-butane, butane or propane；The A of patent CN 1789367
Disclose the mix refrigerant containing R32 and fluoroethane or propylene；The A of patent CN 101157849 disclose fluoroethane, difluoro
The mixture of the material composition such as methane and hydrocarbon substitutes R410A.Though the mix refrigerant in the patent of above-mentioned announcement
So there is relatively low GWP value, but the refrigerant such as fluoroethane, carbon-hydrogen refrigerant is flammable larger, potential safety hazard be present, it is impossible to big
Amount is filled in air-conditioning/heat pump.
In addition, the A of patent CN 101058717 disclose the mixing formed with difluoromethane, pentafluoroethane and fluoroform
Refrigerant；The A of patent CN 1136065 disclose the mix refrigerant formed with difluoromethane, pentafluoroethane and other fluorides；
The A of patent CN 1478849 disclose the ternary mixed refrigerant formed with fluoroethane, pentafluoroethane and difluoromethane；Patent CN
1280165 A disclose the ternary mixed refrigerant formed with propane, pentafluoroethane and difluoromethane；Patent CN 1063300
A, US 649356 and WO 9211339 disclose the mix refrigerant formed with pentafluoroethane, difluoromethane and HFC-134a；Specially
Sharp US 6783691 discloses the quaternary formed with difluoromethane, pentafluoroethane, 1,1,1,2- HFC-134as and hydrocarbon
Mix refrigerant.The GWP that mix refrigerant in above-mentioned patent has is higher, and some refrigerating efficiencies are low, some temperature glides compared with
Greatly, some needs to carry out system the larger R410A improved in ability alternative system.Therefore these refrigerants can not conduct
R410A ideal substitute.
