A method and a ventilator system designed to carry out the method. The method is used to ascertain a current operating point of a ventilator unit having a ventilator and at least one filter. By determining the current operating point, a conclusion can also be drawn regarding the degree of clogging of the filter. It can also be identified whether the filter is present or not. At multiple points in time, a power value for the electrical power of the ventilator can be ascertained. In accordance with the current speed of the ventilator, a power characteristic curve can be selected from a characteristic map or calculated on the basis of a reference characteristic curve which describes the relationship between the electrical power of the ventilator and the pressure differential of the ventilation unit. The power characteristic curve therefore does not only relate to the ventilator but rather to the entire ventilator unit. This allows clear and sufficiently precise determination of the current operating point A of the ventilator unit.
A method for determination of an operating point of a condition of a fan unit that comprises at least one filter and a fan, wherein the method comprises the following steps:
A fan system comprising at least one fan unit and an external computing unit that is communicatively connected with the at least one fan unit that comprises at least one filter and a fan, wherein the fan system is configured to carry out a method for determination of a condition of the at least one fan unit, wherein the method comprises the following steps:
