Abstract
The invention discloses a fluorine-free refrigerant and a preparation method thereof. The fluorine-free refrigerant is prepared by evenly mixing the following raw materials in parts by mass: 30-60 parts of propane, 40-60 parts of propylene, 20-30 parts of isobutane, 10-15 parts of 1,1,1,2-tetrafluoroethane, 10-18 parts of 1,1,2,2-tetrafluoroethane, 2-8 parts of trifluoroiodomethane, 3-12 parts of pentafluoroethyl iodide, 5-15 parts of tetramethyl cyclobutane, 20-30 parts of liquid carbon dioxide and 4-7 parts of cryogenic lubricating oil at room temperature of 20-25 DEG C, wherein the pour point of the cryogenic lubricating oil is -30 to -35 DEG C. According to the technical scheme disclosed by the invention, the ODP value is zero, if the fluorine-free refrigerant is applied in a long term, the fluorine-free refrigerant cannot cause damage to the ozone layer, since the GWP values of the adopted raw materials are all very low and the working pressure is comparable to R22, the change on the existing refrigeration system is not needed and thus the production cost is reduced, the premise that the refrigeration effect of the refrigerant is not reduced can be ensured and meanwhile the refrigerant has effects of suppressing combustion and suppressing explosion.
Description
Technical field
The present invention relates to refrigerant art, more particularly, relate to a kind of alternative chlorofluoro carbon and preparation method thereof.
Background technology
As the global warming potential (GWP) of the important parameter of refrigeration agent, GWP is defined as greenhouse gases with respect to the climate warming potential of carbonic acid gas.The global warming potential of official (GWP) calculates in this way: a kg gas is the ability that warms between 100 years with respect to one kilogram of carbonic acid gas.In the assessment report for the second time that the GWP chart publication of official adopts in inter-governmental climate change Professional Committee (1995IPCCGWP value).GWP value publication more accurately in up-to-date IPCC assessment report, the fluid more friendly to environment, relate in some cases and be suitable for substituting the existing refrigeration agent (for example R410A, R134a, R407C and R404A) with higher global warming potential) fluid, these fluids form the working fluid in refrigeration system, heat pump system and other heat-transfer systems.Identical with the common usage in this area, term used herein " refrigeration agent " is intended to contain all working fluids that play heat transfer effect, and does not consider to use the specific end use of described fluid.So, not should according to term refrigeration agent narrow conclude that the present invention only relates to fluid used in refrigeration system.
Freonll-11 R22 is the refrigeration agent that a kind of thermal property is very excellent, its stable chemical nature, low toxicity, does not fire, and is widely used in for a long time in the equipment such as automative air conditioning, home freezer.But, since scientist finds Chlorofluorocarbons (CFCs) (CFCS), be discharged into atmosphere stratosphere, and understand depletion under action of ultraviolet radiation since, its production and use have been subject to the restriction of international convention.At present, many developed countries have stopped producing, and China is also reducing turnout according to plan year by year, and stop producing the end of the year 2010.Tetrafluoroethane (R134a) can be used on many fields of using R22, but owing to sometimes needing the change of equipment design with this product, so not only the cost of product own is high, simultaneously, whole refrigeration equipment cost also increases thereupon, waste greatly resource, Future Development trend also must be eliminated.Mix refrigerant R406a (R22+R142B+R600A)) be a kind of main products that is used at present substituting R22 and R134a, also can be applicable in the equipment such as automative air conditioning, home freezer, and effect be ideal.But this refrigeration agent exists the problem of high cost in actual applications all the time, thereby apply and be restricted.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, the environmental problem of avoiding Chlorofluorocarbons (CFCs) to cause, can keep good refrigeration simultaneously, and a kind of alternative chlorofluoro carbon and preparation method thereof is provided.
Object of the present invention is achieved by following technical proposals.
Alternative chlorofluoro carbon, by propane, propylene, Trimethylmethane, 1,1,1,2-Tetrafluoroethane, 1,1,2,2-Tetrafluoroethane, CF3I, five fluorine methyl iodide, tetramethyl-ring butane, liquid carbon dioxide and cryogenic freezing lubricating oil form, and wherein, each component mass parts is as follows:
Wherein, the pour point of cryogenic freezing lubricating oil is-30--35 ℃.
The mass parts of each component is preferably as follows:
Wherein, the pour point of cryogenic freezing lubricating oil is-32 ℃.
When being prepared, be chosen under 20-25 degrees Celsius of room temperatures, according to liquid carbon dioxide, cryogenic freezing lubricating oil, propane, propylene, Trimethylmethane, 1,1,1,2-Tetrafluoroethane, 1,1, the order of 2,2-Tetrafluoroethane, CF3I, five fluorine methyl iodide, tetramethyl-ring butane mixes raw material successively, can obtain refrigeration agent of the present invention.
In technical scheme of the present invention, cryogenic freezing lubricating oil is selected according to pour point.
Compared with prior art, it is zero that technical scheme of the present invention has ODP value, life-time service can not damage ozonosphere, the GWP value of the raw material adopting is all very low, and operating pressure and R22 are suitable, without existing refrigeration system is changed, reduced production cost, the refrigeration that can also guarantee refrigeration agent does not decline, there is the effect of combustion and explosion suppression simultaneously, reduce refrigeration agent flammable, refrigeration system security is further improved, the alternative chlorofluoro carbon that the mixed alkanes of employing suitable proportion adds suitable cryogenic freezing lubricating oil to make, the all parts that lubricating oil can be seeped into compressor together with refrigeration agent is that body lubricating creates good conditions.
Embodiment
Below by specific embodiment, technical scheme of the present invention is further described.According to pour point, carry out the selection of cryogenic freezing lubricating oil.According to liquid carbon dioxide, cryogenic freezing lubricating oil, propane, propylene, Trimethylmethane, 1,1,1,2-Tetrafluoroethane, 1, the order of 1,2,2-Tetrafluoroethane, CF3I, five fluorine methyl iodide, tetramethyl-ring butane is mixed with the raw material shown in following table successively.
The refrigeration agent of entrusting Institute for Environment Hygiene and Health Related Product Safety, China CDC to prepare above-described embodiment carries out environmental safety test (test basis is 2002-< < disinfection technology standard > >), Interventions Requested are acute oral toxicity test, result shows that refrigeration agent of the present invention is environmentally friendly, does not have toxicity.The refrigeration agent of entrusting Tianjin Fire Fighting Inst., Ministry of Public Security to prepare above-described embodiment carries out the test of flash-point (GB/T261), limits of explosion (GB/T12474) and spontaneous ignition temperature (GB/T5332), (on average) result shows, under 20-28 degrees Celsius of envrionment temperatures, normal atmosphere 101150-101430Pa, flash-point≤-26 degree Celsius (closed-cup), limits of explosion is 8.2%-22.1%, and spontaneous ignition temperature is 656 degrees Celsius.
