Device for cleaning a fluid, in particular air

[0047] Figure 1 to Figure 4 Shown is an apparatus 1 for cleaning a fluid, in particular air, comprising a through passage 2 for the fluid, a radiation source arrangement 3 emitting electromagnetic radiation 5 and a photocatalytic arrangement 4 which can be exposed at least partially to electromagnetic radiation. radiation 5 to produce a photocatalytic reaction, sensor means 6 are provided to detect at least one change in a radiation parameter of the electromagnetic radiation 5, a control means 7 is signally connected to the sensor means 6, and when the radiation parameter deviates from a set point / threshold or set In the case of a point / threshold range, at least one control parameter of the radiation source device 3 can be adjusted by the control device 7 .

[0048] also, Figure 1 to Figure 6 Shown is a control method for a device 1 for cleaning fluids, in particular air, comprising a through channel 2 for the fluid, radiation source means 3 and photocatalytic means 4, the ...
