Control system for air conditioner

Abstract

Abstract PURPOSE:To promote the saving of energy and enhance comfort during sleeping, by providing a decision means for lapse of time which makes shift temperatures in sleep-mode and lapse of time differ from those of previous time respectively and a shift temperature generating means. CONSTITUTION:When a sleep-mode switch 1 is made ON, a time measuring means 3 measures lapse of time of sleep-mode (tn) and transmits it as a signal to a decision means for lapse of time 5. Upon receipt of sleep-mode switch-ON signal and lapse-of-time signal, the decision means for lapse of time 5 at first outputs the first command signal of shift temperature S1. Thereafter, every time the lapse of time reaches predetermined time t1, t2-, command signals of shift temperatures S2, S3-, are outputted. Upon receipt of these command signals, a shift temperature generating means 6 outputs shift temperature (SIGMASn) to a comparative operational means 10. Then, each shift temperature is compared with differences between room temperatures and set temperatures, whereupon compressor 12 is driven with the reault that room temperatures are controlled in response to shift temperatures.
