Abstract (en)

[origin: EP0056780A2] In the circulation circuit of the working fluid of a first heat pump (1, 5, 6, 8, 10) there is arranged a second heat pump (11 to 14) so that it produces directly a cooling of the fluid. With this arrangement, owing to the second heat pump, the over cooling enthalpy is used and the heat thus obtained, brought to a higher temperature level, may be dissipated as useful heat in addition to the heat provided by the first heat pump.
