| titleOfInvention | A mixed working fluid for heat pumps |
| abstract | The present invention provides a coolant mixture composed of two or three components. A binary non-azeotropic coolant is composed of 1 to 80 percent by mass of R125 and 20 to 99 percent by mass of R152a. A ternary non-azeotropic coolant is composed of 2 to 50 percent by mass of R125, 15 to 97 percent by mass of R152a and 1 to 35 percent by mass of R143a. The coolant mixture is physically blended at normal temperature in the defined proportion, to obtain the corresponding mixed working fluid. The coolant has an ozone depletion potential (ODP) equal to zero, does not destroy the ozonosphere, can reduce the influence of greenhouse effect and is environmentally friendly. The coolant has appropriate thermal parameters and good cycle performance. The coolant can replace a coolant mixture of dichlorodifluoromethane (CFC12) and dichlorofluoromethane (HCFC22), and can be used in the heat pump systems for that coolant mixture. |
