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. -Cramer J. Cramer Silkworth Transsolar Climate

[mailto:rguechchati@gmail.com] 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. Rahma |
