Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/162764
Kind Code:
A1
Abstract:
A refrigeration cycle device comprising: a first refrigerant channel in which a compressor (101), a condenser (102), a first expansion valve (103), a first evaporator (104), and a refrigerant intake port (205) of an ejector (107) are connected by refrigerant tubes; and a second refrigerant channel branching between the condenser (102) and the first expansion valve (103), in which a refrigerant inflow port (204) of the ejector (107), a refrigerant outflow port (206) of the ejector (107), a second evaporator (108), and the compressor (101) are connected by refrigerant tubes; a second expansion valve (105) and an air bubble miniaturizing means (106) for miniaturizing air bubbles in the refrigerant flowing out of the second expansion valve (105) being sequentially connected between the condenser (102) and the refrigerant inflow port (204) of the ejector (107) in the second refrigerant channel; and the opening degree of the second expansion valve (105) being controlled so that the dryness fraction of refrigerant flowing into the air bubble miniaturizing means (106) is greater than 0 and less than 0.1.
