Claims28
A method comprising providing a composition comprising 1,1-difluoroethylene (R-1132a) in a liquid chiller system.
A liquid chiller system comprising:
- at least one counter-flow heat exchanger for exchanging heat between a refrigerant composition and the liquid, said counter-flow heat exchanger allowing the refrigerant composition and the liquid to flow in a counter-current flow relative to each other when the refrigerant composition and the liquid pass through the counter-flow heat exchanger;
- wherein the refrigerant composition comprises 1,1-difluoroethylene (R-1132a) and, optionally, a second component selected from difluoromethane (R-32), 2,3,3,3-tetrafluoropropene (R-1234yf), trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)), 1,1-difluoroethane (R-152a).
A thermal management system of a vehicle comprising:
- a liquid chiller system comprising at least one counter-flow heat exchanger for exchanging heat between a refrigerant composition and the liquid, said counter-flow heat exchanger allowing the refrigerant composition and the liquid to flow in a counter-current flow relative to each other when the refrigerant composition and the liquid pass through the counter-flow heat exchanger;
- wherein the refrigerant composition comprises 1,1-difluoroethylene (R-1132a) and, optionally, a second component selected from difluoromethane (R-32), 2,3,3,3-tetrafluoropropene (R-1234yf), trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)), 1,1-difluoroethane (R-152a), preferably wherein the vehicle comprises an electric vehicle.
