[TRNSYS-users] how much is rotational speed of the desiccant wheel ?

[David BRADLEY via TRNSYS-users]

Amirreza,

   I do not know which desiccant wheel model you are using but the ones 
that I am familiar with do not get into the level of detail of how 
control of the outlet humidity ratio is achieved. You are probably right 
that the wheel speed changes. It may be, however, that the model 
supposes that the power required by the wheel motor is independent of 
wheel speed.

kind regards,

  David
