METHOD OF CONTROLLING PURGE VAVDDC FOR IMPROVING INDOOR ENVIRONMENT OF INTELLIGENT BUILDING

摘要

PURPOSE: An indoor temperature controlling method is provided to control the indoor temperature in an intelligent building equipped with a VAV(Variable Air Volume conditioning) by judging the indoor temperature based on the detected value of a thermistor and outputting a control signal according to the judged result. CONSTITUTION: A method comprises the steps of: purge-varying the errors of the detected temperature of a temperature detecting sensor input to a central control unit and the predetermined target temperature, the change of the errors and input and output variables thereof; purge-assuming by using the values input from a VAV and the central control unit of hot water and cooling and heating plate, purge assuming rules and various purge functions; and controlling the VAV by non-purging the result of purge-assuming output from the central control unit. Herein, the response to the set up temperature is performed promptly and the temperature is kept in uniform state. Therefore, the management of energy and the pleasant indoor condition are satisfied by using a purge-controller.
