preparation example Construction

[0028] The preparation method of a refrigerant composition of the present invention is to combine 1,1,2-trifluoroethylene (R1123), difluoromethane (R32), trifluoroiodomethane (R13I1) and 1,1,1,2 ,2-Pentafluoroethane (R125), make the following combinations:

[0029]

[0030]

[0031] When the combination mode is determined, the refrigerant components are physically mixed in a liquid state at a temperature of 23° C. to 27° C. and a pressure of 0.1 MPa according to their corresponding mass ratios. Among them, trifluoroiodomethane (R13I1) and 1,1,1,2,2-pentafluoroethane (R125) are non-flammable components, and the remaining components can be weakened by controlling the content of non-flammable components. Flammability, so as to meet the safety requirements. The basic parameters of each component material are shown in Table 1.

Abstract

The invention provides a refrigerant composition. The refrigerant composition contains the following components, in percentages by mass: 1%-98% of 1,1,2-trifluoroethylene (R1123), 1%-88% of difluoromethane (R32) and 1%-48% of trifluoroiodomethane (R13I1) or 1%-12% of 1,1,1,2,2-pentafluoroethane (R125). The refrigerant composition has a GWP of 600 or less, an ODP of 0, and obvious environment-friendly advantages; and in addition, the refrigerant composition has good thermal performance and is used for the household air conditioning unit, the capacity and energy efficiency of the household air conditioning unit using the refrigerant composition are equivalent to those of a household air conditioner using an R410A refrigerant, and the can refrigerant composition replace the R410A working medium without any change of the household air conditioning system.

Description

technical field [0001] The invention relates to a refrigerant technology, in particular to a refrigerant composition which can be used for domestic air conditioners. Background technique [0002] With the increasingly serious trend of environmental protection, regarding the "greenhouse effect" of HFCs, the Montreal Protocol Amendment requires a refrigerant that does not destroy the ozone layer and has a lower GWP value to replace the current high-GWP refrigerant and be effectively used in air-conditioning systems middle. For example, R410A, which is commonly used in household air conditioners and multi-split units, has a GWP of 2100 and an ODP of 0. At present, technical means often start from the perspective of single working substance and refrigerant composition, and look for work that meets both environmental protection requirements and air conditioning system capacity and energy efficiency requirements. Quality, but have not yet found a more perfect substitute for R410A...
