Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/103436
Kind Code:
A1
Abstract:
A refrigeration cycle device comprises: a first refrigerant circuit which is formed by connecting the refrigerant discharge section of a compressor (101), a condenser (102), a first expansion valve (103), a first evaporator (104), and the refrigerant suction section (205) of an ejector (105); a second refrigerant circuit which is branched from the connection piping between the outlet side of the condenser (102) and the first expansion valve (103) and is connected to the refrigerant inlet section (204) of the ejector (105); and a third refrigerant circuit which is formed by connecting the diffuser section (refrigerant outflow section)(203) of the ejector (105), a second evaporator (106), and the refrigerant suction section of the compressor (101). The first evaporator (104) and the second evaporator (106) are water heat exchangers for exchanging heat between a refrigerant which flows through the refrigerant circuits in which the first evaporator (104) and the second evaporator (106) are respectively disposed and a liquid heat medium which is different from the refrigerant. The liquid heat medium is supplied from the outside, flows sequentially through the second evaporator (106) and the first evaporator (104), and is discharged to the outside.
