ABSTRACT:
According to the present invention, in an air-mixing type air conditioning apparatus in which an air-mixing door is disposed at an air upstream side of a heater core and without having a hot water control valve for shutting off a flow of hot water into the heater core, a warm air passage formed at an air downstream side of the heater core is narrowed by a foot door in a face mode where a face air passage is closed by a face door. In this way, in the maximum cooling operation, with the foot door, it is possible to favorably suppress the air heated by hot water in the heater core from being mixed into cool air by natural convection.
