Abstract

The invention relates to a refrigerant mixture combining three components, in particular to a ternary non-azeotropic refrigerant, which comprises the following components by weight percent: 2-50% of R125, 15-97% of R152a and 1-35% of R143a. The refrigerant mixture is formed by physical mixing at normal temperature according to the established mixture ratio, thereby getting a corresponding mixed working medium. The ODP (ozone depression potential) of the refrigerant is zero, an ozone layer is not damaged, and the impacts caused by greenhouse effect can be reduced, thereby being in line with requirements of environment friendliness; and thermal parameters are appropriate, and the circulation performance is good. The refrigerant mixture can replace the refrigerant mixture of dichlorodifluoromethane (CFC12) and difluorochloromethane (HCFC22) and be used in a heat pump system of the refrigerant mixture.

Description

technical field [0001] The invention relates to a refrigerant mixture, especially a refrigerant mixture used in a heat pump system, which is used to replace the heat pump system containing CFCl2 or HCFC22 and used in the refrigerant mixture. Background technique [0002] Since 1987, global actions to protect the ozone layer, phase out ozone-depleting substances, and reduce the greenhouse effect are being carried out in countries around the world in accordance with the Montreal Protocol. Our country has begun to actively carry out substitution work, and finding safe, efficient and environmentally friendly alternative refrigerants has become an urgent and important task. [0003] Due to the high ozone depletion potential (ODP) of CFC refrigerants, they are strictly controlled in Montreal and subsequent revisions. HCFC refrigerants, unlike CFC, HCFC only partially replaces the hydrogen atoms with halogen atoms, and the remaining hydrogen atoms help the chemical to partially de...
