HEAT EXCHANGE SYSTEM AND REFRIGERANT CYCLE INCLUDING HEAT EXCHANGE SYSTEM

A heat exchange system includes a dual expansion valve for a refrigerant cycle of a vehicle that includes a first inlet and a first outlet, a first flow restriction mechanism including a movable first valve element, by which a first refrigerant stream flowing through a first passage from the first inlet to the first out let can be controlled, a second inlet and a second outlet, a second flow restriction mechanism including a movable second valve element, by which a second refrigerant stream flowing through a second passage from the second inlet to the second outlet can be controlled, a control member for jointly moving the first valve member and the second valve member, a sensing element for sensing a temperature, and a valve driving member that is configured to drive the control member according to the sensed temperature.
