Abstract
The invention relates to an HCR22 (Hydrocarbon Refrigerant 22)-containing hydrocarbon refrigerant and application thereof as a heat transfer fluid. More particularly, the invention relates to a refrigerant including 70-90 percent of C3H6 and 10-30 percent of C3H8. HCR22 is low in freezing point, larger in latent heat of evaporation to ensure that the cooling speed within unit time is higher; small isentropic compression ratio ensures that a compressor works more easily and the service life of the compressor is prolonged; in addition, the HCR22-containing hydrocarbon refrigerant has the advantages of small molecular weight, good fluidity and low conveying pressure and reduces the load of the compressor.
Description
Technical field
The present invention relates to comprise HCR22 carbon-hydrogen refrigerant and it purposes as heat-transfer fluid.
Background technology
Confer the caused problem of material by loss atmospheric ozone layer (ODP: ozone depletion potentiality) in Montreal, signed in Montreal and forced to reduce the manufacture of Chlorofluorocarbons (CFCs) (CFC) and the protocol of use.This protocol has formed the theme of such amendment, described amendment require to cancel CFC and by regulations administration extensions to other products, comprise Hydrochlorofluorocarbons (HCFC).
The industry of refrigerating industry and manufacture air-conditioning has been carried out great amount of investment in the alternative aspect of these refrigeration agents, and therefore hydrocarbon (CH) goes on the market.
In automotive industry, the air-conditioning system of the vehicle of selling in many countries becomes the hydrogen fluorohydrocarbon less to the harm of ozonosphere (HFA 134a: propane) refrigeration agent from Chlorofluorocarbons (CFCs) (CFC-12) refrigeration agent.But from the viewpoint of the target that set by the Kyoto Protocol, propane (GWP=1300) is considered to have high calorific value (heating power).Refrigeration agent is that GWP (global warming potential) quantizes to the contribution of Greenhouse effect by standard, and GWP is the concentrated reflection of calorific value, using carbonic acid gas as benchmark value 1.
Because carbonic acid gas is nontoxic and non-flammable and has low-down GWP, therefore substitute using carbonic acid gas as the propane refrigeration agent as air-conditioning system is proposed.But, use carbonic acid gas to there are some shortcomings, the described shortcoming particularly very high pressure with use carbonic acid gas as refrigerant in existing installation and technology time is relevant.

nhydrogen fluorine propylene (particularly tetrafluoeopropene and trifluoro propene) as the purposes of heat-transfer fluid.
Document WO 2004/037913 discloses the composition that comprises at least one fluoroolefin with 3 or 4 the carbon atoms purposes as heat-transfer fluid, and described fluoroolefin is five fluorine propylene and tetrafluoeopropenes particularly, preferably have 150 GWP at the most.
Document WO 2005/105947 has instructed to tetrafluoeopropene (preferably 1,3,3,3-tetrafluoeopropene) middle blowing promotor (coblowing agent), for example methylene fluoride (HFC-32), pentafluoride ethane (HFC-125), Tetrafluoroethane, C2H4F2 C2H4F2, heptafluoro-propane, HFC-236fa, pentafluoropropane, 3-pentafluorobutane, water and the carbonic acid gas of adding.
And in natural refrigerant, this natural refrigerants of alkane (silly guilt hydrogen compound again, HC is its abbreviation), has zero ozone depletion value (ODP) and extremely low Greenhouse effect value (GWP).
Summary of the invention
Object of the present invention, be to provide one have zero ozone depletion value (ODP) and extremely low Greenhouse effect value containing HCR22 carbon-hydrogen refrigerant.
The present invention not only has zero odp but also have the GWP lower than the GWP of existing HFC, HCFC, CFC containing HCR22 carbon-hydrogen refrigerant.Concrete technical scheme is:
A kind of containing HCR22 carbon-hydrogen refrigerant, it is characterized in that they comprise 70 ~ 90 quality %C3H6,10 ~ 30 quality %C3H8.
Further, a kind of containing HCR22 carbon-hydrogen refrigerant, it comprises 70 ~ 80 quality %C3H6,10 ~ 20 quality %C3H8.
Further, a kind of containing HCR22 carbon-hydrogen refrigerant, it comprises 80 ~ 90 quality %C3H6,20 ~ 30 quality %C3H8
A kind of be used on air conditioner as the substitute of R22 containing HCR22 carbon-hydrogen refrigerant, can be used as heat-transfer fluid and be particularly suitable for for artificial atmosphere, it is preferably as the substitute of R22.
HCR22 carbon-hydrogen refrigerant zero pour of the present invention is low, and vaporization heat is larger, makes interior cooling rate of unit time faster; Isoentropic compression is less than merit, makes compressor operating lighter, extends the work-ing life of compressor; Molecular weight is little, good fluidity, and transfer pressure is lower, has reduced the load of compressor.Use HCR22 carbon-hydrogen refrigerant, fractional energy savings can reach 15-35%.
The mixed rate of oil of HCR22 carbon-hydrogen refrigerant of the present invention is high, with all conventional refrigeration lubrication oil (mineral lubricating oils, ucon oil) compatibility, nontoxic, to metal and the equal non-corrosiveness of oil resisting rubber.And many refrigeration agents need special supporting refrigeration agent lubricating oil, as improper use, will go wrong, use carbon-hydrogen refrigerant can prevent refrigeration agent and the incompatible problem causing of refrigeration agent lubricating oil.
