Abstract: In a heating medium channel switching device, a valve body whose interior is partitioned into two channels by a partition plate is axially rotated by a motor, whereby a relative position of the valve body in a valve chamber is controlled. Because of this, one of a first heating medium and second heating medium can be selected and caused to flow out in one channel, and one of a third heating medium and fourth heating medium can be selected and caused to flow in the other channel. Also, heating medium flow can be controlled by an angle of rotation of the valve body being controlled.

Abstract: A compound valve includes a body having a valve chamber; a cylindrical-shaped valve element having opening portions in its lateral side surface for allowing heat media to flow inside of the valve element, and a partition member there inside in the longitudinal direction; and a motor for controlling a rotation angle of the valve element, and the opening portions communicate with either one of a first heat-medium inflow port or a second heat-medium inflow port, and with either one of a third heat-medium outflow port or a fourth heat-medium outflow port; two heat media having different properties flow adjacent to the partition member; and, by controlling, by a rotation angle of the motor, areas of the communicating inflow ports and the opening portions, and those of the communicating outflow ports and the opening portions, the quantities of flow are controlled.

Abstract: A heat-medium flow-path switching device and a heat-medium flow-rate adjusting device are integrated into an integrated heat-medium flow-rate adjusting device. The integrated heat-medium flow-rate adjusting device is configured to perform the heat-medium flow-path switching function and the meat-medium flow-rate adjusting function by driving and controlling a single drive unit. Moreover, the integrated heat-medium flow-path switching device is configured to perform a function of closing flow paths from/to a use-side heat exchanger added to the heat-medium flow-rate adjusting function.
