Engineering field, for realizing device depth cooling and liquefaction of industrial gasses etc., such as low temperature refrigerator, natural gas liquefaction etc.
Field.In addition to the hardware facility such as refrigeration system flow and compressor and heat exchanger, the Refrigeration Technique it is the most key be polynary
Mix refrigerant.
Because the Basic Physical Properties parameter such as the boiling point by constituent element, freezing point temperature is limited, in addition also constituent element working medium can
Combustion property, other physicochemical properties such as toxicity, the optional constituent element under the effective constituent element of mixed working fluid, especially low temperature are very limited.
By some mandates or apply for a patent at present and be related to low-temperature mixed-refrigerants and form and concentration proportioning, its Patent
ZL97115295.0, ZL03121423.1, ZL03121467.3, CN201010608844 and ZL03121466.5 divide warm area to propose
It is used for the serial multicomponent mixture work medium of copious cooling throttle Refrigeration Technique, wherein constituent element has the fluorination of nitrogen, alkane and part alkane
Thing is formed, mixture ozone free damage effect.Each constituent element of mixture is divided into low-temperature space constituent element, normal refrigeration temperature according to boiling point difference
District's groups member, high temperature district's groups member and high-temperature region constituent element, each warm area constituent element obtain the polynary mixed of demand according to a concentration ratio
Working medium is closed, there is higher thermodynamic efficiency.The alkanes substances such as the methane, ethane and the propane that wherein contain have and lubrication
The good intersolubility of oil, and greenhouse effects are small, and environmental protection characteristic is good, but it is certain flammable that system can be caused to exist.And by
In the presence of combustible component so that system is required to consider the measure such as explosion-proof, increase production in links such as production, debugging, maintenances
The difficulty that cost and user receive, especially in North America market.
There is patent application ZL01802606.0 to propose with the hydrofluoride (HFCs) of nitrogen (N2), argon gas (Ar) and alkane
With perfluoro-compound (FC), such as the composition such as R23, R125, R134a, R236fa and R245fa non-combustible Diversity refrigeration
Agent, wherein minimum temperature can realize 105K, also be formed containing neon (Ne), helium (He) etc..The patent is also according to refrigeration
Warm area is different, and different zones are divided into according to its boiling point for the constituent element in mixture, by each warm area different boiling constituent element according to
Finite concentration proportion forms whole mixt, and its whole mixture is free of flammable alkane constituents, also not hydrogeneous fluorine chlorine
Hydrocarbon (HCFC) class has the component of ozone layer destroying, but its efficiency is poor compared with the mixture containing alkane, and is wherein kept away to use
Exempt from combustibility, the higher boiling constituent element such as its non-combustible HFC classes material such as HFC125, HFC236fa for choosing is respectively provided with higher greenhouse
The latent value (GWP) of effect.
It is another to there is United States Patent (USP) US5408848 to propose a kind of mixed working fluid Refrigeration Technique for using and being free of CFC constituent elements, with full
The refrigeration demand of minimum more than -150 DEG C of foot, wherein being given in embodiment based on R142b, R134a, R23, R14 and Ar
Mixed working fluid composition.Combustible component is free of in mixture composition, but is wherein HCFC materials containing R142b, is had smelly
Oxygen layer damage effect, belong to the row of limitation and disabling.
