[TRNSYS-users] weird Qcool

Dear Wang,
As far as I understand, the cooling set temperature you define in your
model is :
* 24°C in summer, which seems to be correct
* and 0°C in winter... which seems to be wrong, since you don't
refresh your thermal zone at 0°C in winter!
That's why you obtain huge cooling loads.
BAL_ENERGY is not 0 because you heat and cool in the same time in winter.
I think you'd better put for cooling temperatures
* 35°C in winter (no cool) - heating temperature at 21°C
* 24°C in summer
which may be translated in an equation tool by something like :
* summer = GE(TIME,2162)*LT(TIME,6552)
* winter = 1 - summer
* Tcool = 35*Winter - 9*Summer
Best regards
