Problems solved by technology

[0003] The existing products on the market are dominated by R-22 freon, R-410A and R-134a, which account for more than 98%. R-22 is an internationally recognized ozone-depleting substance, and R-410A and R-134a generally have a strong greenhouse effect. High (GWP), and these types of refrigerants occupying more than 98% of the market have no power-saving effect, which is still a relatively large impact on the serious problem of the ozone layer hole and energy depletion.

Abstract

The invention discloses a novel refrigerant which mainly comprises a mixture, wherein the mixture is formed by mixing propane (R290) and isobutane (R600a), the mixture comprises the following components in percentage by mass: 10%-90% of the propane (R290) and the balance of the isobutane (R600a) and a small quantity of difluoroethane (R152b), tetrafluoroethane(R134a), liquid carbon dioxide and tri-oxygen ethane, and azeotropic or approximate azeotrope proportion is achieved. Compared with the prior art, the novel refrigerant disclosed by the invention has the characteristics of environmental friendliness and energy saving, is embodied in causing no damage on an ozone layer, generating no greenhouse effect and achieving better energy conservation in practical application and can bring the real economic benefit for a customer; and as for certain other refrigerants, compared with systems, such as an air conditioner which uses R-22 and other refrigerants, and the like, the novel refrigerant disclosed by the invention can at least save 15% of electricity and averagely saves more than 20% of electricity.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and energy saving, in particular to a novel refrigerant. technical background [0002] The global warming potential (GWP), which is an important parameter of refrigerants, is defined as the climate warming potential of greenhouse gases relative to carbon dioxide. The official global warming potential (GWP) is calculated this way: the warming capacity of a kilogram of gas relative to 1 kilogram of carbon dioxide over 100 years. The official GWP chart is published in the Second Assessment Report adopted by the Intergovernmental Panel on Climate Change (1995 IPCC GWP values). More accurate GWP values ​​published in the latest IPCC assessment report), more environmentally friendly fluids, in some cases involving suitable replacement for existing refrigerants with higher global warming potential (such as R410A, R134a, R407C and R404A) fluid. These fluids constitute the working flui...
