Process for the heating and/or thermal conditioning of a building by means of a heat pump operated with a specific mixture of working fluids

摘要

Buildings are advantageously heated or heat-conditioned with a heat pump operated with a non-azeotropic mixture of two working fluids. The mixture comprises 99 to 70% by mole of dichlorodifluoromethane (R 12), monochlorodifluoromethane (R 22) or one of the halohydrocarbon azeotropes R 500, R 501 or R 502 with 1 to 30% by mole of trifluoromethane (R 23) or the halohydrocarbon azeotrope R 503.
