PURPOSE:To avoid the generation of too low or too high blow-out temperatures due to the delay of response of a sensor by a method in which the temperature is corrected on the basis of elapsed time from the startup or stoppage of the supply of a refrigerator and detected temperatures by the sensor of temperatures after chilling, and exact temperatures after chilling are detected. CONSTITUTION:In a ventilation duct 1, an evaporator 15 for chilling is provided to occupy all cross section of the duct 1, and a temperature regulation mechanism 19 is set on the downstream side. Air is divided into air flow passing through a heater core 20 occupying a part of the cross section of the duct 1 and air flow to bypass the core 20. Detected outputs of a temperature setter 25, open air temperature sensor 26, vehicular internal temperature sensor 27, insolation sensor 28 and temperature sensor 29 after chilling are put in a control circuit 24, and air flow is divided by an air mixing damper 21 so that a target blow-out temperature is obtained. Actual air temperature after chilling can be calculated from the time elapsed from a time when a compressor 40 is turned from OFF to ON and detected temperatures by the sensor 29. |
