Abstract

PURPOSE:To reduce input power to auxiliary machines and to save energy by driving the auxiliary machine whose input power is less based on the sensed data of the temperature or the load. CONSTITUTION:Based on the sensed data of the temperature and the load factor, the required cooling capacity of a cooler group 4 is computed in a data processing device 5. Based on the result, the number of operating coolers and the input power to the auxiliary machines 17 and 18 are computed by using the number of the coolers and a computer program 8. The required speeds and the input powers of the auxiliary machines 17 and 18 are computed by a motor speed and input computation program 9. The inputs to the auxiliary machines from the programs 8 and 9 are compared and judged by an input comparing and judging program 10. A control signal is transmitted to a unit number control system 11 or speed control system 12 which is judged to have the less input power to the auxiliary machine. Based on the signal from the program 10, the system 11 controls the number of operating units, and the system 12 controls the speeds of the auxiliary machines 17 and 18.
