SYSTEM AND METHOD FOR PREDICTING LOAD OF AND CONTROLLING SUBWAY HEATING, VENTILATION, AND AIR CONDITIONING SYSTEM

摘要

A system for predicting load of and controlling a subway heating, ventilation, and air conditioning system. In one aspect, provided is a system for predicting load of and controlling a subway heating, ventilation, and air conditioning system. The system comprises a basic database, a sensing system, a load prediction portion, and a controller. The basic database stores historical data. The sensing system provides actually measured data. The load prediction portion calculates a predicted load value of a subway heating, ventilation, and air conditioning system on the basis of the historical data and the actually measured data, and transmits the predicted load value to the control portion. The controller issues a control command on the basis of the predicted load value to control operation of the subway heating, ventilation, and air conditioning system. The historical data and the actually measured data comprise strong time-varying data. Also provided is a method for predicting load of and controlling a subway heating, ventilation, and air conditioning system. The present invention resolves the problems of poor accuracy of conventional load prediction and inadequate control of air conditioning systems.
