Abstract (en)

[origin: WO0240613A1] The invention relates to the use of liquids containing 1,1,1,3,3-Pentafluorobutane (R365mfc) and at least one other partly fluorized hydro carbon from the 1,1,1,2-Tetrafluoroethane (R134a), Pentafluoroethane (R125), 1,1,1,3,3-Pentafluoropropane (R245fa) and 1,1,1,2,3,3,3-Heptafluoropropane (R227ea) groups as the operating liquid in high temperature heat pumps. Cooling liquids used according to the invention are characterised by a high temperature drift.
