METHOD FOR CONTROLLING PRESSURE KEEPING FACILITY FOR COOLING AND HEATING SYSTEM PROVIDED WITH PLURALITY OF SENSORS

摘要

The present invention pertains to a method for controlling a pressure keeping facility for a cooling and heating system. More specifically, a pressure keeping facility is provided with a plurality of sensors for measuring equal physical quantities, and the abnormalities of the sensors are detected according to the method so as to control the operation of the pressure keeping facility under optimum conditions. According to the present invention, the abnormality of a predetermined sensor is detected using measurement values of two or more of the plurality of sensors; and the measurement value of the sensor, which is determined as being abnormal, is excluded in deciding a control reference value. Therefore, it is possible to carry out pressure control corresponding to the states of a real system.
