Abstract

Dual mode heat exchange circuit, comprising: a first and a second heat exchanger each operable in a first mode wherein heat is released, and in a second mode wherein heat is absorbed; a compressor and/or expander, arranged between the first heat exchanger and the second heat exchanger; a first valve arranged between the heat exchangers at a first heat exchanger side; a second valve arranged between the heat exchangers at a second heat exchanger side; an expansion valve for regulating a flow rate in the circuit, arranged between the first and second valves; a pump; and a buffer container arranged between the first valve and the expansion valve, wherein the circuit is selectively operable in a heat pump mode or a Rankine cycle mode. Advantageously, circulating working fluid charge can be regulated and/or modulated so as to optimize performance in both the heat pump mode and the Rankine cycle mode.
