PURPOSE:To maintain the temperature in a car-room stably without any influence of the sunshine by estimating the amount of the solar radiation which a car receives on the basis of the thermal difference between sunshine-receiving parts and unreceiving parts for compensating the adjusting amount of temperature. CONSTITUTION:An air-mix damper (A/M damper) 7 changes the temperature of the air to be blown off by changing the rate of the cooled air from a cooling heat- exchanger 5 to pass through a heating heat-exchanger 6. An air-pressure operator 19 of an electromagnetic valve control type is linked with the A/M damper 7, and determines the position of the A/M damper 7 on the basis of the command signal from an electric control device 20, which is constructed to estimate the adjusting amount of temperature on the basis of signals received from thermal detectors 21- 23 arranged at various parts of a car, a temperature setter 24, a position detector 25, and a switch 26 for maintaining the temperature in a car-room at a level commanded by the temperature setter 24. |
