A control apparatus of a heat exchanging system according to the invention activates a connection system (60) to connect an engine water passage (16, 11W, 17, 18, 12W, 19) to a heater water passage (40, 33W, 41, 31W, 42, 34W, 45, 46) and then, shuts off a heater water passage portion between a portion, into which heat exchanging water flows from the engine water passage and a portion, from which the heat exchanging water flows out toward the engine water passage, and decreases heater pump and engine pump duty ratios (DH and DE) when the duty ratios should be decreased for controlling core and engine flow rates (Vhc and Veng) to requested flow rates (Vhc_req and Veng_req) after the particular water passage is shut off, and the engine water passage is connected to the heater water passage.
