Abstract

PURPOSE: To prevent offsetting of the aging degradation due to inconsistency in maneuvering of the apparatus to prolong the lives of apparatuses by alternately operating two cooling and heating cycle apparatuses, storing the content of operation and making uniform the maneuvering of respective apparatuses.
CONSTITUTION: When the temperature of air and contamination degree within a compartment 8 varies by the increase or decrease in the number of passengers, it is detected by a detector 9, and its detection signal is amplified by an operation amplifier 25. The thus amplified signal is converted into a digital signal by an A/D converter of an entrance circuit 26, and sent to a CPU27. In the CPU27, an electrical signal sent from the outside is compared with memory signals of RAM, and EPROM28 and 29 which are set values, and difference signals are computed. The result of the computation is given to driving circuits 22W24 through an entrance circuit 26 and an actuator amplifier 30, and the compressor, indoor and outdoor fans and a four-way valve are driven to operate the entire air-conditioning system.
