R227ea (heptafluoro-propanes, CF3-CHF-CF3) relative molecular mass is 170.03, and boiling point is -16.45 DEG C, and gasification latent heat is smaller, it is 136 J/g (O.101 3 MPa), critical-temperature is 101.65 DEG C, and critical pressure is 2.926 MPa, and critical density is 573 g/m3, saturated vapor pressure is 0.389 MPa at 20 DEG C, it is nontoxic non-ignitable with good heat endurance and chemical stability, non-corrosiveness；Environmental performance is superior：Its ODP value is 0, and GWP value is 1004, and reserve life is short in an atmosphere；R227ea is a kind of good fire retardant, and its suppression combustion property is better than R125.
R245fa (pentafluoropropane, CF3CH2CHF2) relative molecular mass is 134.0, and boiling point is 15.3 DEG C, and freezing point is -160 DEG C, and the solubility in water is 0.16%, and gas conduction rate is 14.0 mw/m.k at 40 DEG C, and environmental performance is superior：Its ODP value is 0, and GWP value is 790, and reserve life is short in an atmosphere；It is a kind of good fire retardant.
Current air source heat pump technology as heating equipment industry a focus, various product emerges in an endless stream.The a few years time, among having there is domestic and international enterprise of hundreds of families to add air source heat pump production to sell on China's air-conditioning market.But by working medium, heating capacity is limited in itself, air source heat pump is when environment temperature reaches -25 DEG C, reach 55 DEG C of leaving water temperature, refrigerant condensing temperature is at 63 DEG C or so, such compression ratio has exceeded the tolerance range of compressor, compressor electric motor is caused to be closed, whole hot pump in low temp system is stopped.If can develop can at -25 DEG C the also larger refrigerant of heating capacity, will advance China's air source heat pump northern area development progress.
The content of the invention
It is an object of the invention to provide one group of air source heat pump trilogy supply unit mixed working fluid, it is to ozone damped expoential（ODP）It is 0 to be worth, to causing the greenhouse effects extent of injury（GWP）It is 94.5~184.8 that value is interval, meets current protection atmospheric ozone layer, reduces the environmental requirement new trend of Global Greenhouse Effect.
Present invention is introduced：One group of air source heat pump trilogy supply unit mixed working fluid, containing R1234ze -1,3,3,3- tetrafluoropropenes（C3H2F4）, R227ea-heptafluoro-propane（CF3-CHF-CF3）With R245fa -1,1,1,3,3- pentafluoropropanes（CF3-CH2-CHF2）Three kinds of constituent element materials, it is characterized in that：The mass fraction of R1234ze is that the mass fraction that the mass fraction of 80%~90%, R227ea is 5~10%, R245fa is 5 ~ 10% in mixed working fluid.
The preparation method of mixed working fluid of the present invention is that each group urmaterie is carried out into physical mixed at normal temperatures by its quality proportioning specified.
The present invention has advantages below and beneficial effect：
（1）Meet environmental requirement：ODP of the invention be equal to zero, GWP value be 94.5~184.8 between.Its environmental characteristics is excellent, meets Ozonosphere protection, reduces the requirement of greenhouse effects.（2）Thermal parameter is suitable：It is suitable for 20-110 DEG C of condensation temperature, you can produce 55 DEG C of hot water.
The basic parameter of each constituent element is shown in Table 1.Each thermal physical property parameter value of mix refrigerant is shown in Table 2 under saturation state.
