Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/018298
Kind Code:
A1
Abstract:
The flow volume ratio of the flow volume of refrigerant flowing from a branch part (13) into a nozzle part (14a) of an ejector (14) and the flow volume of refrigerant flowing from the branch part (13) into a suction-side evaporator (21) is set in advance to a value which achieves a high cycle efficiency. In addition, the heat exchange core part of an outflow-side evaporator (16) that evaporates the refrigerant flowing from a diffuser part (14d) of the ejector (14) is divided into a first core part (16a), which exhibits a cooling capacity for cooling a chilling chamber (Ci), and a second core part (16b), which exhibits a cooling capacity for cooling a freezer chamber (Fr). Therefore, the chilling chamber (Ci) is cooled with the cooling capacity exhibited by the first core part (16a), and the freezer chamber (Fr) is cooled with the cooling capacity exhibited by the second core part (16b) and the suction-side evaporator (21).
