ADJUSTING METHOD OF TEMPERATURE

PURPOSE:To attain optimum temperature control independently of the number of passengers by finding the working ratio within a fixed period and compensating the set temperature of the succeeding period in accordance with the size of the working ratio in a temperature adjuster for a train. CONSTITUTION:A set temperature T2 is compensated by a set point correcting circuit 4 and then compared with a detected temperature T1 by a deviation detecting circuit 5. A deviation output DELTAT is integrated by a deviation integrating circuit 6 and then added to the deviation output by an adding circuit 7 and the added output is ued for working an air conditioner as a working signal S1. When a control system is stable, DELTAT=0 is formed, the deviation input T of the adding circuit 7 is acted only transiently and the integrated output S' of the deviation integrating circuit 6 controls temperature mainly. By integrating the signal S' by a definite integral circuit 8 for a fixed period, the working ratio S2 is obtained and the compensated value S3 is outputted from the circuit 4 by a correction value generating circuit 9.
