Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/135805
Kind Code:
A1
Abstract:
A refrigeration cycle device (100) is provided with a refrigerant circuit (106), an injection flow path (111), and a high-pressure introduction flow path (130). The refrigerant circuit (106) has a low-pressure stage compressor (105), a high-pressure stage compressor (101), a heat radiator (102), an expander (103), a gas-liquid separator (108), and an evaporator (104). The expander (103) and the low-pressure stage compressor (105) are connected by a power recovery shaft (107). The refrigeration cycle device (100) is also provided with a flow path switching mechanism for selectively connecting either the evaporator (104) or the high-pressure introduction flow path (130) to the low-pressure stage compressor (105). The flow path switching mechanism comprises, for example, an on-off valve (131) and a check valve (132).
