Abstract
The invention discloses a refrigerant, which comprises the following parts: 35-60% petahydrofluoeic ether, 35-60% difluoromethane and 0. 1-10% propane. The allocation doesn't contain the material to break ozone layer, which can lubricate the freezing system road.
Description
Technical field
The present invention relates to a kind of refrigeration agent, especially relate to a kind of energy and substitute R22 and be applicable to refrigeration agent in the corresponding refrigeration equipment.
Background technology
Fluorine Lyons R22 is the very excellent refrigeration agent of a kind of thermal property, and its chemical property is stable, and low toxicity, does not fire, and is widely used in occasions such as large-size air conditioning, unit cooler for a long time.But, find that from scientist Chlorofluorocarbons (CFCs) (CFCS) is discharged into the atmosphere stratosphere, since the meeting depletion, its production and use are subjected to the international convention restriction under action of ultraviolet radiation, restriction to R22 all the time constantly aggravates, at the output boil down to 65% of China R22 in 2003; To be compressed to 35% in 2010; Boil down to 10% in 2015; The year two thousand twenty is completely forbidden, to the year two thousand thirty comprehensively superseded R22 in the whole world.And developed country is limited to 2010 during to the forbidding of R22.
Because R22 eliminates that the die is cast, the research of seeking its surrogate launches rapidly just in the world.From actual, R22 also exists the whole world to become high, energy consumption (COP) height of dim coefficient (GWP) value except meeting depletion (ODP) defective, and to the problem of the unlubricated effect of refrigeration system pipeline.
Summary of the invention
For overcoming the above-mentioned defective that prior art exists, the present invention aims to provide a kind of refrigeration agent, and this product has not depletion, and Greenhouse effect value, power consumption values are low, and the advantage that refrigeration system pipeline is had lubricant effect.
For achieving the above object, the present invention has adopted following technical scheme: this refrigeration agent is mixed by pentafluoride ethane 35-60%, methylene fluoride 35-60%, the propane 0.1-10% of following weight per-cent.
Beneficial effect: the contriver is by repeatedly experiment, the refrigeration agent of selecting for use pentafluoride ethane, methylene fluoride and Halothane to mix does not contain the material that destroys depletion (ODP) in the component, because the physicochemical property of these three kinds of materials, therefore, have lower Greenhouse effect value and power consumption values.In addition, because the existence of propane has had lubricant effect preferably to refrigeration system pipeline.
Embodiment
After this refrigeration agent was found time container and pipeline at normal temperatures, with pentafluoride ethane R125, methylene fluoride R32 and propane R290 carried out physical mixed by its weight percent and get final product.
Propane among the present invention (R290), molecular formula CH3CH2CH3; Pentafluoride ethane (R125), molecular formula: CHF2CF3; Methylene fluoride (R32), molecular formula: CH2F2.
Embodiment 1: by weight percentage, get 5% propane, 50% pentafluoride ethane and 45% methylene fluoride carry out physical mixed at normal temperatures, as refrigeration agent.
Embodiment 2: by weight percentage, get 0.1% propane, 50.9% pentafluoride ethane and 49% methylene fluoride carry out physical mixed at normal temperatures, as refrigeration agent.
Embodiment 3: by weight percentage, get 6% propane, 45% pentafluoride ethane and 49% methylene fluoride carry out physical mixed at normal temperatures, as refrigeration agent.
Embodiment 4: by weight percentage, get 4% propane, 36% pentafluoride ethane and 60% methylene fluoride carry out physical mixed at normal temperatures, as refrigeration agent.
Embodiment 5: by weight percentage, get 3% propane, 40% pentafluoride ethane and 57% methylene fluoride carry out physical mixed at normal temperatures, as refrigeration agent.
Embodiment 6: by weight percentage, get 7% propane, 43% pentafluoride ethane and 50% methylene fluoride carry out physical mixed at normal temperatures, as refrigeration agent.
Embodiment 7: by weight percentage, get 2% propane, 55% pentafluoride ethane and 43% methylene fluoride carry out physical mixed at normal temperatures, as refrigeration agent.
Embodiment 8: by weight percentage, get 8% propane, 57% pentafluoride ethane and 35% methylene fluoride carry out physical mixed at normal temperatures, as refrigeration agent.
In the table 1, the contrast index is respectively: destroy ozone latent energy value ODP, the whole world becomes dim coefficient value GMP, energy loss-rate COP, refrigerating duty.As seen from the table, the every index of refrigeration agent of the present invention all is better than R22, particularly destroys ozone latent energy value ODP and is zero, can not damage the ozone layer.
Table 1: each embodiment and refrigeration agent R22 performance are relatively
