摘要:
To provide a working medium for heat cycle which has less influence over the ozone layer, which has less influence over global warming and which provides a heat cycle system excellent in the cycle performance (the efficiency and the capacity), and a heat cycle system excellent in the cycle performance (the efficiency and the capacity). A working medium for heat cycle comprising 1,2-difluoroethylene is employed for a heat cycle system (such as a Rankine cycle system, a heat pump cycle system, a refrigerating cycle system 10 or a heat transport system).

摘要:
A refrigerant composition consisting essentially of a hydrofluorocarbon component consisting of: R227ea 3-9% R134a 25-70% R125 3-35% R32 10-35% together with an optional hydrocarbon component, wherein the amounts are by weight and are selected to total 100%, can be used as a replacement for refrigerant R22 in existing equipment.
摘要:
An environmentally friendly hydrocarbon refrigerant mixture may be used as a substitute for existing refrigerant in a refrigerant system. The hydrocarbon refrigerant mixture offers greater operating efficiency and effectively replaces chlorofluorocarbon refrigerants. The refrigerant mixture for the refrigeration system includes from about 85% to about 89% by weight propane and from about 11% to about 15% by weight propene.
摘要:
A composition includes between 11 and 13 wt. % of difluoromethane; between 58 and 62 wt. % of pentafluoroethane; between 18 and 29 wt. % of tetrafluoropropene; and between 0 and 7 wt. % of propane. The tetrafluoropropene can be 1,3,3,3-tetrafluoropropene or 2,3,3,3-tetrafluoropropene. The composition can be used as a heat transfer fluid in a vapor compression circuit.
