Example of description function of devices in block circuit diagram Rosenberg Fans
Example for Inlet air device Heating, with hot water pump, switch box, options:
- Inlet air temperature control
- Room temperature control
Application of description function of devices in block circuit diagram Rosenberg Fans:
Ventilation system for rooms in which the inlet air temperature or room temperature should be held
constant by warming or cooling the inlet air.
Function of description function of devices in block circuit diagram Rosenberg Fans:
The temperature measured by the inlet air sensor B1, room sensor B2 or outlet air sensor B3 is compared by the controller with the adjusted set point. In the event of a deviation, the controller displaces the heating valve.
