Description
Technical field
The invention belongs to refrigerant arts, and in particular to a kind of novel refrigerant for substituting R22.
Background technique
As the refrigerant in air-conditioning, heat pump, refrigeration system and cryogenic refrigerating system, difluoro one is mostly used after long-term
Chloromethanes (R22) destroys ozone layer latent energy value (ODP) 0.034, global warming coefficient value (GWP) 1700.1987, by 26
" the Montreal ozone-layer depleting substance management agreement book " that country signs jointly limits previous common halocarbon
Use.It is provided according to the script of Montreal protocol, developed country will stop completely non-feedstock property in the year two thousand thirty
R22 production and consumption, developing country (including China) will stop the R22 production and consumption of non-feedstock property in the year two thousand forty.But
In September, 2007 is advised in the newest resolution that the Montreal protocol conference of contracting party that Montreal, CAN is held is reached
Fixed, developed country will stop completely the R22 production and consumption of non-feedstock property in the year two thousand twenty, the development China including China
Family, the production and consumption amount by non-feedstock property HCFCs (wherein about 70% is R22) in 2013 be frozen in 2009 and
In average level in 2010, the year two thousand thirty completes to eliminate comprehensively.Compared to original superseded timetable, entirely superseded process mentions significantly
Before, and the systems such as about 80% domestic air conditioning/heat pump of domestic production at present and application make refrigerant using R22, it can be seen that,
The substitution situation of R22 is very severe and research and development of substitute are extremely urgent.
Existing either simplex matter refrigerant, performance are not better than R22 comprehensively, and the R22's on current domestic and international market is main
Substitute includes the mixture refrigerants such as R410A (R32/R125) and R407C (R32/125/134a), but these substitutes are still not
Ideal, the operating pressure of the two are above R22, and wherein the condensing pressure ratio R22 high of R410A about 57%, is not suitable for using
It is directly filled in the system of R22.R407C is since there are biggish temperature slippages also as just a kind of transition refrigerant.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of novel refrigerant.The operating pressure base of the refrigerant and R22
This consistent and high pressure slightly reduces, and effectively reduces the energy consumption of compressor, refrigerating capacity can reach 100% of R22 or more, and save
Energy rate can reach 20% or more；ODP is 0, gwp close to 0, nontoxic and pollution-free and good with the lubricating oil compatibility of former R22 system
Direct filling to substitute R 22, and the filling quantity of refrigerant can be reduced, it is easy to use, reduce energy consumption.
The purpose of the present invention is what is be implemented with the following technical solutions, a kind of novel refrigerant, raw material is by following quality hundred
The group of ratio is divided to be grouped as: dimethyl ether 10~40%；Carbon dioxide 10~15%；Propylene 10~50%；Propane 5~25%；Trifluoro iodine alkane 5
~10%；Additive 1~3%.
Preferably, additive is water.
The preparation method of this novel refrigerant is that each component is carried out logistics mixing by quality proportioning under liquid environment.
Novel refrigerant is used for air-conditioning or refrigeration equipment.
Beneficial effects of the present invention:
(1) propylene physical parameter and R22 are extremely close, and saturated vapor pressure-temperature curve of propylene and R22 are very close, institute
With, using propylene as the refrigerant of working medium as R22 alternative refrigerant when, the basic item of original system main component can not be changed
Part and directly charge.
(2) ODP of propane is 0, GWP almost in 0.He is cheap, this effectively reduces the cost of refrigerant.
(3) for carbon dioxide as a kind of natural medium refrigerant, environment-protecting and non-poisonous, safe and reliable, economical and energy saving is non-combustible
Burn, when temperature is lower, scale is bigger, Energy Efficiency Ratio height and investment economy sexual clorminance be just more obvious CO2 will not contaminated food products, institute
The fields such as low temperature, super low temperature refrigeration and quick-frozen, food product refrigeration can be chiefly used in.
(4) critical-temperature of carbon dioxide is 31.1 DEG C, boiling point is -56.6 DEG C, and the critical-temperature of dimethyl ether is
126.85 DEG C, boiling point be -25 DEG C, show differing greatly in terms of its physical property therebetween.Therefore, carbon dioxide can be
It is utilized as refrigerant in low pressure about 3MPa~high pressure about 10MPa pressure limit very high in this way, and dimethyl ether can be
It is utilized in low pressure about 0.7MPa~high pressure about 2MPa pressure limit lower in this way as refrigerant, it can be in such pressure
Most excellent performance is played under the conditions of power as refrigerant.By the higher carbon dioxide of heat-transfer effect in physical property (0.02W/mK) and
Obtain showing the physical property refrigerant of the high thermal efficiency with dimethyl ether (138J/molK) mixing compared with high specific heat.
(5) refrigerant of the invention uses liquid carbon dioxide and trifluoroiodomethane, themselves is non-combustible as explosion-proof
Flame retardant reduces combustibility while guaranteeing refrigerant working medium, increases the security performance of refrigerant, improves refrigerant
Filling quantity.
(6) in some embodiments, water is as additive, under worst hot case, since water has evaporation (condensation) latent heat
Higher feature, and rate of temperature change is smaller relative to evaporation latent heat due to critical point is higher, obtains refrigerant bigger
Efficiency.
(7) refrigerant of the invention, ODP 0, gwp are lower than 150, meet European Union Emission standard, are a kind of environmentally protective
Refrigerant.Additionally, due to the synergistic effect of multicomponent working medium, refrigerant of the invention can be ok under the operating condition of senior middle school's low temperature
Play effect well.
