Abstract
An air conditioning apparatus suitable for an electric car without a hot water source, while preventing the windshield from fogging up when switching from a cooling or dehumidifying operation to a heating operation. Upon the commencement of a heating operation following the end of a preceding cooling or dehumidifying operation lasting for a period longer than a predetermined value, a switching damper 104 is forced to move to the outside air inlet position 104A, when it is determined that a predetermined first time has not elapsed from the end of the last cooling or dehumidifying operation, and a predetermined second time has not elapsed from the commencement of the first heating operation following the end of the last cooling or dehumidifying operation.
