REFRIGERANT DIVIDER

WIPO Patent Application WO/2014/083627

A1

A refrigerant divider (100) is provided with: a body (1); piping (2) which allows a refrigerant to flow into the body (1); connection pipes (3a, 3b) which allow divided refrigerant portions formed in the body (1) to respectively flow out toward heat exchange sections (25a, 25b); regulation valves (30a, 30b) which are provided within the body (1) and which, by means of valve bodies (12a, 12b), adjust the degree of opening of openings (31a, 31b) which respectively connect to the connection pipes (3a, 3b); and a drive device (40) which reduces the degree of opening of the adjustment valves (30a, 30b) on the basis of the pressure difference obtained by subtracting the pressure of refrigerant portions measured at the outlets of the heat exchange sections (25a, 25b), the outlets being located on the side opposite the connection pipes (3a, 3b), from the pressure of refrigerant portions measured within the body (1) at the positions of the openings (31a, 31b) which face the piping (2), the reduction in the degree of opening of the adjustment valves (30a, 30b) being performed in such a manner that the greater the pressure difference, the smaller the degree of opening of the adjustment valves (30a, 30b). Thus, the refrigerant divider (100) which can adjust the flow dividing ratio of the refrigerant according to various types of disturbance is provided.
