[esp-r] Re: containment of fan

[Jon Hand]

In case this question was not answered....

If you have defined the fan as part of an air flow network then what you
need to do is to create an entry in the model control file for the branch of
the flow network associated with the fan component.  Sense the temperature
of the air flow node in the room you are interested in and actuate the fan or
volume flow component. There are a number of control laws available
for such components ON/OFF, PI, range-based controls. There are
examples of imposing control on flow components within the training folder
of ESP-r.  The ESP-r Cookbook discusses the design and implementation
and control of air flow networks.

If you define the fan as part of a component based plant network then
you would define a control law and sensor and actuator within that
domain.

And there is an abstract approach that you can use to impose changes
in scheduled air infiltration as part of a zone operation file.  It could be as
simple as altering the default assumption about infiltration rates to a different
value if the room temperature or the outside temperature was greater than
a specific temperature.

Subject: [esp-r]  containment of fan

Hi

I have created a mechanical ventilation for practice using ESP-r.
.
Currently, component selection and conecction ended.

I think when the ambient temperature goes from 18 degrees to 27 degrees, and I want to ON the fan.

However, I do not know how do I define the control of the fan.

Please let me know.

Thanks.
