PURPOSE:To improve the accuracy of automatic control temperature in an automatic air-conditioner without causing variation of blow-out temperature due to outer-injection condition, by calculating the blow-out temperature from the actually measured air temperature passing through a heater core then maintaining the calculated temperature to the target level. CONSTITUTION:The temperature immediately after core THC to be detected by a temperature sensor 15 immediately after a heater core is read out to calculate the blow-out required for maintaining the setting room temperature TSET and to perform ON-OFF control of compressor 8 on the basis of the outer air temperature TA. Then the correction DELTAX of an air-mix door 5 is obtained from air- mix door opening X, necessary blow-out temperature TOF, air temperature immediately after evapolator TEVP and air temperature THC immediately after the heater core, to provide to an actuator 9 thus to match the amount of blow- out air with TOF and to control the room temperature TIC to the setting room temperature. In such a manner, the air-mix door can be controlled without influence of the outer air temperature or the water temperature distribution in the heater core and the room temperature can be maintained accurately to the setting level. |
