WIPO Patent Application WO/2018/173490
Kind Code:
A1
Abstract:
A heat pump (1), provided with an engine drive compressor (13), an electric compressor (16), an oil separator (20), an electric compressor discharge pipe (85), and an engine drive compressor discharge pipe (81). The oil separator (20) separates lubricant oil included in a refrigerant discharged by an engine drive compressor (13) and an electric compressor (16). The electric compressor discharge pipe (85) extends from the electric compressor (16) and discharges the refrigerant towards the oil separator (20). The engine drive compressor discharge pipe (81) extends from the engine drive compressor (13) and discharges the refrigerant towards the oil separator (20). At least a part of the engine drive compressor discharge pipe (81) on the upstream side, with respect to the direction in which the refrigerant is discharged, of the portion at which the engine drive compressor discharge pipe (81) merges with the electric compressor discharge pipe (85) is made of a flexible tube (82, 83).
