Air conditioning plant using a heat pump with a static exterior heat exchanger and with dry vapour regulation by automatically changing the rate of flow through the expansion valve.

摘要

Heat pump used in air conditioning and in heating, the condenser and evaporator of which are constituted by two exchangers, one (1) of which, outside the room, is a static exchanger made up of a finned tube, characterised by regulating means (138-B) which serve to regulate the throughput of the expander (13) so as to maintain the point of the circuit of the evaporator, downstream of which the heat- exchanging fluid is completely vaporised, somewhat beyond the point of exit from the evaporator. <IMAGE>
