Abstract
The invention provides an environment-friendly chlorofluorocarbon-free refrigerant and a preparation method thereof. The refrigerant is prepared from propane, propylene, cyclobutane, 2,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene, trifluoromethyl iodide, pentafluoromethyl iodide, difluoromethane, tetrahydrothiophene, liquid carbon dioxide and cryogenic lubricant. The refrigerant has the beneficial effects that the ODP value is zero, the ozone sphere cannot be destroyed if the refrigerant is used for a long time; the GWP value of raw materials is low, and the working pressure of the refrigerant is equivalent to that of R22, so that an existing refrigeration system need not to be modified, the production cost can be reduced, while the refrigeration effect is not reduced; the refrigerant has the effects of inhibiting combustion and explosion, so that the combustibility of the refrigerant can be reduced, and the safety can be improved; the lubricant can seep into each part of a compressor together with the refrigerant so as to create an excellent condition for engine lubrication; tetrahydrothiophene is easily dissolved in difluoromethane and has a strong unpleasant smell, so that when the refrigerant leaks, a user can feel leakage of the refrigerant at the first time and carries out corresponding measures, so that property and safety of people can be protected.
Description
Technical field
The present invention relates to refrigerant art, more particularly, relate to a kind of environmental protection 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 the climate warming potential of greenhouse gases relative to carbonic acid gas.The global warming potential (GWP) of official calculates in this way: a kg gas is relative to the warm ability of one kilogram of carbonic acid gas between 100 years.The GWP chart publication (1995IPCCGWP value) in the second time assessment report of inter-governmental climate change Professional Committee employing of official.GWP value publishes fluid in up-to-date IPCC assessment report, more friendly to environment more accurately, relate in some cases being suitable for substituting and there is the existing refrigeration agent (such as R410A, R134a, R407C and R404A) of higher global warming potential) fluid, these fluids form the working fluid in refrigeration system, heat pump system and other heat-transfer system.Identical with the usual usage in this area, term " refrigeration agent " used herein is intended to contain all working fluids playing heat transfer effect, and does not consider the specific end use using described fluid.So, should narrowly not conclude that the present invention only relates to fluid used in refrigeration system according to term refrigeration agent.
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 that Chlorofluorocarbons (CFCs) (CFCS) is discharged into air stratosphere, and under action of ultraviolet radiation since meeting depletion, it is produced and uses the restriction receiving 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 the many fields using R22, but owing to sometimes needing the change of equipment de-sign with this product, so not only the cost of product own is high, simultaneously, whole refrigeration equipment cost also increases thereupon, waste resource greatly, Future Development trend also must be eliminated.
Mix refrigerant R406a (R22+R142B+R600A)) be used for a kind of main products of alternative R22 and R134a at present, also can be applicable in the equipment such as automative air conditioning, home freezer, and effect is ideal.But there is the problem of high cost in actual applications in this refrigeration agent, thus applies and be restricted all the time.
Summary of the invention
Instant invention overcomes deficiency of the prior art; refrigeration agent life-time service can damage ozonosphere; the leakage of refrigeration agent cannot be perceived in the very first time; and refrigeration agent has the security that combustibility cannot ensure refrigeration system; provide a kind of environmental protection alternative chlorofluoro carbon and preparation method thereof, Ozonosphere protection, life-time service can not damage ozonosphere; there is the effect of combustion and explosion suppression, improve the security of refrigeration system further.
Object of the present invention is achieved by following technical proposals.
Environmental protection alternative chlorofluoro carbon, by propane, propylene, tetramethylene, 2,2,3,3-tetrafluoeopropene, trans-1,3,3,3-tetrafluoeopropene, CF3I, five fluorine methyl iodide, methylene fluoride, tetramethylene sulfide, liquid carbon dioxide and cryogenic freezing lubricating oil composition, wherein, each component mass parts is as follows:
Wherein, the pour point of cryogenic freezing lubricating oil is-25--40 DEG C.
The mass parts of each component is preferably as follows:
Wherein, the pour point of cryogenic freezing lubricating oil is-34 DEG C.
When being prepared, select at room temperature 20-25 DEG C, according to liquid carbon dioxide, cryogenic freezing lubricating oil, propane, propylene, tetramethylene, 2,2,3,3-tetrafluoeopropene, trans-1,3, raw material mixes by the order of 3,3-tetrafluoeopropene, CF3I, five fluorine methyl iodide, methylene fluoride, tetramethylene sulfide successively, can obtain refrigeration agent of the present invention.
In the inventive solutions, cryogenic freezing lubricating oil carries out selecting 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 adopted is all very low, and operating pressure is suitable with R22, without the need to changing existing refrigeration system, reduce production cost, can also ensure that the refrigeration of refrigeration agent does not decline, there is the effect of combustion and explosion suppression simultaneously, reduce refrigeration agent flammable, refrigeration system security is improved further, the mixed alkanes of suitable proportion is adopted to add the obtained environmental protection alternative chlorofluoro carbon of suitable cryogenic freezing lubricating oil, the all parts that lubricating oil can be seeped into compressor together with refrigeration agent is that body lubricating creates good conditions, simultaneously, because tetramethylene sulfide is soluble in methylene fluoride, and tetramethylene sulfide has strong unhappy smell, the stink produced is stablized, is not easily distributed, there is 0.01PPm in air just can smell, when there is refrigrant leakage, user can perceive the leakage of refrigeration agent in the very first time, and taking appropriate measures, thus protection people property safety.
Embodiment
Below by specific embodiment, technical scheme of the present invention is further described.
The selection of cryogenic freezing lubricating oil is carried out according to pour point.According to liquid carbon dioxide, cryogenic freezing lubricating oil, propane, propylene, tetramethylene, 2,2,3,3-tetrafluoeopropene, trans-1, raw material is mixed with by the order of 3,3,3-tetrafluoeopropene, CF3I, five fluorine methyl iodide, methylene fluoride, tetramethylene sulfide successively.
