Title:
FLOW RATE ADJUSTMENT VALVE FOR REFRIGERATION CYCLE
Document Type and Number:
WIPO Patent Application WO/2013/172201
Kind Code:
A1
Abstract:
A flow rate regulation valve (19) is used for a refrigeration cycle device for air conditioning. The flow rate regulation valve (19) is constituted by: an inlet flow rate control valve (19a) connected to the inlet side of an indoor evaporator (20) and functioning in the refrigeration cycle device as an expansion valve for depressurizing and expanding a refrigerant flowing into the indoor evaporator; and an outlet flow rate adjustment valve (19b) connected to the outlet side of the indoor evaporator (20) and functioning as an evaporation pressure adjustment valve for adjusting evaporation pressure in the indoor evaporator (20) to a predetermined target pressure at which frost is not formed. The flow rate regulation valve (19) is characterized in that, when the degree of opening of one of the inlet flow rate control valve (19a) and the outlet flow rate adjustment valve (19b) increases, the flow rate regulation valve (19) displaces so that the degree of opening of the other decreases.
