PROBLEM TO BE SOLVED: To complete recovery of a heat exchange fluid of high temperature to a heat-accumulation vessel in an early stage as early as possible after starting of drive of an engine without sacrificing fuel economy of an internal combustion engine and comfortability in a cabin. SOLUTION: After starting of drive of the engine 1, recovery of cooling water in a fluid circuit 6 to the heat-accumulation vessel 41 by execution of cooling water recovery treatment is performed in an early stage as early as possible on condition that both warming of a transmission 10 and heating in the cabin 25 are completed. Even if cooling water of low temperature is released from the heat-accumulation vessel 41 accompanying with recovery of cooling water to the heat-accumulation vessel 41 and flows into the fluid circuit 6, it does not cause delaying of completion of warming of the transmission 10 and delaying of completion of heating in the cabin 25. This fact is because warming of the transmission 10 and heating in the cabin 25 are already completed at recovery of the cooling water to the heat-accumulation vessel 41. Thus, deterioration of fuel economy of the engine 1 accompanying with delaying of completion of warming of the transmission 10 and reduction of comfortability of an occupant in the cabin 25 accompanying with delaying of completion of heating in the cabin 25 are suppressed.
