More Information
Summary:The disclosed temperature control system for an air conditioner includes a sensor for sensing an actual air temperature and a comparator for determining the temperature difference between the sensed actual air temperature and a set air temperature after their conversion to digital voltages. The temperature difference is stored in a memory and is also applied to a calculator where a rate of change in temperature per unit time is calculated from the temperature difference thus formed and from that temperature which had occurred just before a predetermined time stored in the memory. A control unit responds to both the temperature difference and the rate of change in temperature per unit time to increase or decrease the number of compressors put into operation with respect to the number of the compressors operated at the just preceeding interval of time.
