OPTIMUM START-STOP CONTROL METHOD

摘要

PURPOSE:To perform the optimum start-stop control with high accuracy by deciding the optimum start and stop time points of that relevant day from the past data. CONSTITUTION:The temperature of a room is sent to a controller 2 from a temperature sensor 1 set within the the room, and an air conditioner 3 is controlled by the controller 2 according to the temperature information. In this case, the room temperature of that relevant day is detected to obtain the difference from the target temperature and then the estimated temperature change rates alpha and beta of the previous day or a specific day are read out. The optimum start and stop time points are decided from the temperature difference of that day and said rates alpha and beta to start and stop the conditioner 3. While the rates alpha and beta are calculated and stored from the time during which the target temperature is obtained as well as the temperature difference of that day. Thus the warm-up time and the stop period are obtained from the room temperature and the target temperature to decide an optimum start/stop time point for control.
