Definitions
- the present invention relates to a composition based on HydroFluoroCarbures (HFC), suitable for use in refrigeration.
- HFC HydroFluoroCarbures
- the azeotrope consisting of 48.8% by weight of chlorodifluoromethane
- HCFC-22 or R-22 chloropentafluoroethane
- CFC-15 chloropentafluoroethane
- HCFC HydroChloroFluoroCarbure
- a ternary mixture consisting of 44% by weight of pentafluoroethane (HFC-125), 52% by weight of 1, 1, 1 trifluoroethane (HFC-143a) and 4% by weight of 1, 1, 1, 2 tetrafluoroethane (HFC-134a), known as R404A was used to replace R-502.
- HFC-125 pentafluoroethane
- HFC-143a 1, 1, 1 trifluoroethane
- R404A 1, 1, 1, 1, 2 tetrafluoroethane
- non-azeotropic composition comprising 10 -90% by weight of difluoromethane (HFC-32), 10-90% by weight of HFC-125, 10-60% by weight of propene (HC-1270), 10- 90% by weight of HFC-134a and containing up to 20% by weight of impurities is known from CN 1 183451 A.
- a refrigerant composition replacing HCFC-22, containing from 10 to 25% by weight of HFC-32, from 20 to 60% by weight of HFC-125, from 20 to 60% by weight of HFC-134a and from 2 to - 5% by weight of a hydrocarbon or a hydrocarbon mixture having 3 to 5 carbon atoms is described in JP 2004- 175998.
- US 2004/0061091 discloses a mixture, replacing HCFC-22, consisting of 20-60% by weight of HFC-134a, 40-70% by weight of HFC-125, 1 -10% by weight of HFC-32 and 1-8% of a hydrocarbon mixture.
- the object of the present invention is to provide a composition that can be used as a refrigerant and that meets the desire for a lower environmental impact.
- the present invention therefore has as its first object a composition comprising 15 - 25% by weight of difluoromethane (HFC-32), 50 - 60% by weight of pentafluoroethane (HFC-125), 15 - 25% by weight of 1, 1, 2 tetrafluoroethane (HFC-134a) and 1 - 3% by weight of propene (HC-1270).
- composition according to the present invention preferably comprises 17 - 23% by weight of difluoromethane (HFC-32), 50 - 58% by weight of pentafluoroethane (HFC-125), 20 - 25% by weight of 1, 1, 1, 2 tetrafluoroethane (HFC-134a) and 1 - 3% by weight of propene (HC-1270).
- HFC-32 difluoromethane
- HFC-125 pentafluoroethane
- HFC-134a 1, 1, 1, 1, 2 tetrafluoroethane
- propene HC-1270
- the composition according to the present invention comprises 19-21% by weight of difluoromethane (HFC-32), 53-58% by weight of pentafluoroethane (HFC-125), 21-23% by weight of 1.1-1, 2 tetrafluoroethane (HFC-134a) and 1 - 3% by weight of propene (HC-1270).
- HFC-32 difluoromethane
- HFC-125 pentafluoroethane
- HFC-134a 2 tetrafluoroethane
- propene HC-1270
- the present invention also relates to a composition refrigerant according to the first object. It also relates to the use of refrigerant replacing the R-404A.
- the following table gives for each of the formulations the cooling capacity (CAPA), namely the quantity of cold produced (kJ) per unit of volume sucked (m 3 ), the COP (ratio of the cold power to the power absorbed by the fluid compressor), the condensing pressure (bar) and the GWP.
- CAA cooling capacity
- kJ quantity of cold produced
- m 3 volume of volume sucked
- COP ratio of the cold power to the power absorbed by the fluid compressor
- bar condensing pressure
- compositions of this invention have similar performances (COP, CAPA) to those of R-404A, higher than those of R-22 for a GWP much lower than that of R-404A and of the same order of magnitude as that of R-22.
- pressure levels remain consistent with those of R-404A equipment.
