Abstract

PURPOSE:To obtain same effect as the analog integration operation in an air conditioner control with a microcomputer by utilizing a timer counter function to add the operation signal data to a memory at predetermined interval. CONSTITUTION:A microcomputer 10 processes predetermined program a signal from by a timer counter 17 at predetermined interval. The data such as set temperature 11, car temperature 12, ambient temperature 13 and the like are read and processed at predetermined interval and are written in an operation memory 18 and at the same time the operation results are added to an integration data storage memory until such value exceeds the predetermined value which is then replaced by predetermined value to be added further to the contents of the operation memory 18 and the results thereof are outputted as a control signal to a negative pressure control means 21. By repeating this operation the integration operation can be obtained. The integration time constant can be easily set by a program.
