ABSTRACT:
A heating apparatus of a re-heat type for an air conditioning system for a vehicle provided with an internal combustion engine. The heating apparatus includes a flow control valve for controlling an amount of an engine hot water directed to a heat exchanger for heating. When the degree of the opening of the flow control valve is 2/8 or less and when the target degree of the opening of the flow control valve is 2/8 or more, a control of the degree of the opening of the flow control valve to the target opening plus a predetermined overshoot amount is initially executed, which is followed by a control to the target opening. When both of the initial and target opening is larger than 2/8 or the initial and target opening are identical, the overshoot control is not carried out, i.e., the degree of the opening of the flow control valve is directly controlled to the target value.
