Re: [TRNSYS-users] active layer



Rahma,

 

What exactly are you trying model? Do you want the active layer to maintain the zone temperature?  You can certainly use the active layer to maintain the zone temperature (though probably not perfectly constant with an active layer) using a differential controller (such as Type 2) that monitors the zone temp and controls the active layer massflow rate, and you can simply ignore the output temp or override it with an equation...but why you'd ever do such a thing is not clear to me. Constant input and output temps for the slab doesn't make any sense, physically.

Hello;

 

     I want to simulate a monozone (Type 56) heated by an active layer where it circulates the hot water (heated by a thermal solar colector) but the temperature of the zone remains unchanged (before and after heating) and the temperatureof the fluid of input and the output are equal.

 

       Thank you and with my greeting.
