Abstract:
A control apparatus of a heat exchanging system according to the invention executes a control for activating a connection system to connect an engine water passage to a heater water passage and a control for increasing an engine pump duty ratio, and then executes a control for decreasing a heater pump duty ratio when the control for decreasing the heater pump duty ratio and the control for increasing the engine pump duty ratio are requested to be executed in order to control a core flow rate to a requested core flow rate and an engine flow rate to a requested engine flow rate after the engine water passage is connected to the heater water passage by the connection system.
