Re: [TRNSYS-users] Flowrate Control

[David BRADLEY <d.bradley@tess-inc.com>]

Amani,
  It should be possible to use the PID controller to obtain the outlet temperature that you want but without having your project, it isn't possible to know what is incorrect. This is the kind of question you should address to your distributor.

  As a side note, if you have access to the TESS HVAC library, there are a number of heat exchanger models in that library that are set up to allow control based on outlet temperature of either the hot or the cold side.
Kind regards,

Dear TRNSYS users, 

In my model ( a solar wood dryer) , i have a diverter connected to a heat exchanger water/air.

I want to control the flowrate at outlet 1 of the diverter to maintain the heat exchanger cold-side temperature at a desired value. I tried with the PID controller but the problem lies in the components connections.

Please help me through this problem.

  

Best regards.
