dear all,
the following
situation occurred during a fairly simple simulation with only one room, an
irregular ventilation rate and an ambient temperature: even though the room
temperature was above the set temperature for the heating the heating was turned
on (sensible energy demand negative). at first sight i thought this would happen
because trnsys wants to avoid the room temperature to drop below the set
temperature during the time step. but first of all it happens no matter how
small my time steps are and secondly it also happens even though the temperature
increases due to the heating (say 20° is my set temperature, 20,5° is my room
temperature at time step i and due to further heating it increases to 21° at
time step i+1). my question therefore is: can anyone explain to me the
trnsys-internal controlling mechanisms for heating? isn't it supposed to be an
ideal controller?
thanks in
advance,
jörn
