Abstract: A method for determining an efficiency of a cooling system including a plurality of electrically powered cooling devices, the cooling system is configured to ramp the total cooling capacity up and down by turning the one or more cooling devices on and off either fully or partly. The method involves providing corresponding values of estimated electrical power consumption and total rated cooling capacity and monitoring and recording the total electrical power consumed by the system.

Abstract: A control method is provided for a filter system, which includes at least one filter element (2). The method includes continuously recording a total energy consumption (EG) during a filtration cycle (22) of the filter system. The total energy consumption (EG) includes at least of the energy consumption (EB) for a physical cleaning (24) and the energy consumption (EP) for the subsequent production cycle (23) up to a predefined, in particular current point in time. The method further includes computing a relative energy consumption (Erel) by way of division of the recorded total energy consumption (EG) by a net permeate volume (QN) which has been produced during the filtration cycle (22) up to the predefined point in time and starting a physical cleaning (24) in dependence on the relative energy consumption or of a characteristic value derived from this.
