摘要： The invention concerns a method and device for controlling a distillation or condensation apparatus including a distillation vessel, heat source and condenser. A distillation or condensation apparatus consumes considerable quantities of cooling water which is discharged, through a length of hose connected to the condenser, directly into the drain. The aim of the invention is to propose a method and device for controlling a distillation or condensation apparatus to ensure a significant reduction in cooling-water consumption. The method proposed achieves this by virtue of the fact that the cooling water flowing through the condenser of the distillation or condensation apparatus is passed round in a closed loop, its temperature is measured in this loop and, when an upper temperature limit is reached, cooling water is replaced by feeding in cold water until a lower temperature limit is reached. The device proposed achieves the aim stated above by means of a cooling-water regulator connected to the condenser of the distillation or condensation apparatus through a pump to form the cooling-water loop, a valve connected to a cold-water supply line and operated by a controller, plus a temperature sensor located in the cooling-water loop, the controller operating the valve so that, when the upper cooling-water temperature limit is reached, the valve is opened until the cooling-water temperature reaches the lower limit.
