Abstract (en)
[origin: WO2010054498A1] A heat pump system operable in a cooling mode, a heating mode and a defrost mode includes a refrigerant compressor (20), a reversing valve (30), a first heat exchanger (40) and a second heat exchanger (50) disposed in a refrigerant circuit, and a primary expansion valve (45) disposed in the refrigerant circuit between said first heat exchanger (40) and said second heat exchanger (50); said reversing valve (30) is positionable in a first position for operation of said heat pump system in the cooling mode or defrost mode and is positionable in a second position for operation of said heat pump system in the heating mode; a refrigerant bypass circuit establishes a refrigerant flow path from the refrigerant circuit at a first location upstream of said primary expansion valve (45) and downstream of said first heat exchanger (40) with respect to refrigerant flow in the defrost mode to a liquid reservoir (70) disposed in the refrigerant circuit at a second location downstream of said primary expansion valve (45) with respect to refrigerant flow in the defrost mode.
