[TRNSYS-users] PID controler

[Adrien JEZEQUEL <a.jezequel@itf.biz>]

Hi Trnsys users,

I have to model a heat pump in a swimming pool building (in order to 
dehumify ambient air). In that way, I would like to control the heat 
pump in order to maintain a relative humidity around 65-70%. I have 
begun with a project which was ever build by an other person of my 
company. She had used several heat exchangers to model heat pump. 
Nowadays, I would like to control water flow rates (used to cool or heat 
air) in order to obtain an ambient relative humidity constant. I tried 
to control these flow rates with PID controlers, but without success.

So, is there somebody who is able to explain me how to use PID 
controler? May I follow another way to manage that control?

Thanks in advance for your help.

Best regards, Adrien
