Abstract (en)
[origin: EP2602571A1] The device (1) has periphery heat exchanger (11) and air heat exchanger (12) which are arranged in the main circuit (2). An expansion valve (32) in series to expansion valve (31) is arranged in the expansion valve line (212). A hot-water heat exchanger (13) is connected with the additional compressor (22) through a feed line (131), and an expansion valve (33) is flow-connected to main circuit through return line (132). The feed line is flow-connected to the main compressor line (211), and the return line between expansion valves (31,32) is flow-connected with expansion valve line. An independent claim is included for method for operating reversible heat pump device.
