Abstract

PURPOSE:To forecast the minimum time until a device drain collecting tank reaches an upper limit amount with good accuracy, by detecting the maximum amount of device drainage at each different time interval from the past data and performing a specified operation based on this value. CONSTITUTION:A control device 30 detects the maximum amount of device drainage at each specified different interval from the past drain amount, calculates the difference between the liquid amount in the drain collecting tank and the upper limit amount of this tank, selects the closest maximum generating amount to the said difference out of the detected maximum amount, and forecasts the minimum time until the liquid amount reaches the upper limit amount in the tank, based on the selected maximum generating amount, a specified time interval corresponding to the said maximum amount and the said difference. The distribution of the drainage is controlled by using this forecasting method.
