Further developments of a heating, ventilation and air conditioning system (HVA), in particular further developments of a drive, are presented here. In the prior art, HVA systems are known in which, for example in the case of ventilation or water applications, in particular, flap drives for ventilation flaps or control valves are used to regulate a volume flow. In application variants, the volume flow relates to an airflow or a water flow for heating, ventilation and air conditioning functions, wherein, in particular, open-loop or closed-loop control of volume flows is necessary. Components of HVA systems have to be reliable and cost-effective and have a long service life. |
