[TRNSYS-users] weird Qcool

Dear Mr. Adrien,
Many thanks for your quick reply!
Did you put a lower ACH for the simulation already? After that, the cooling
system works fine? I did. I set the ACH from 2.0 to 0.5 1/h, however, Qcool
is still 0, in addition, Tair_room in summer is up to 33/34 °C. It means
the cooling system is still not working after reducing the ACH of
ventilation system.
So I think it is not reason of ventilation system. I guess there is
something wrong with the cooling system in TRNSYS. But I still can't find
the solution.
Please give us some suggestions for that! I don't know why there are so
many bugs or problems in TRNSYS although it has been a mature BES tool.
Many thanks in advance!

>> Do you have some solutions to make sure that the set point is 21 °C in
>> winter?
>>
>> check Tair without internal heat gain and solar gain to be sure that

>>
>>
>> 2.Tair and Top are lower than the set point 26 °C in summer all the time.
>> The maximal is only 25.4 °C. I guess the reason is due to the influence of
