Abstract
An air-conditioning apparatus for use in a vehicle includes bypass means for forming a bypass duct to allow the air which has passed through an evaporator to bypass an heater core, opening/closing means for opening and closing the bypass duct, and refrigerant control means for switching between a supply state in which refrigerant is supplied to the evaporator to a stop state in which the supply of the refrigerant to the evaporator is stopped based on a temperature of air having just passed through the evaporator. When it is determined that a physical amount relating to the temperature of the air introduced into a casing is greater than a predetermined amount and when the control state of the refrigerant control means is switched from the stop state to the supply state, the bypass duct is closed for a first predetermined time period by control means with the opening/closing means. In this way, it is possible to prevent the foggy air from being generated.
