  • Modelling a Fan Control
  • KULI-System

    The aim of a decent fan control strategy is to provide adequate air flow for the cooling system at minimum fan power and noise.

    The KULI controller objects enable to implement an arbitrary  control strategy for system optimization. 

    In the subsystem Fan control the controlling information is set up. For comfortable use you can change the values for the temperatures for changing the fan stage and the fan stages itself in the inner circuit window. 

    Based on the fan (electrical or mechanical fan) the fan stage or the fan speed can be used as the controlled parameter. In the provided model an electrical fan switches on as the air temperature rises above 60°C and switches off as the temperature falls below 55°C. The transient aspect of the example is the hysteresis which can be modeled using a delay controller. For better system overview the control strategy is packed into a KULI subsystem.
