[TRNSYS-users] indoor temperature is unstable

[大大宝]

Dear TRNSYS users, 


I am validating my model with a experimental room (room). The room has a floor heating system and I simulated the indoor temperature in the case of floor heating turning off. 


I input the collected weather data(weather1.txt) into the simulation (room.b18 & room.tpf). 


I compared my simulated indoor temperature with the measured one. I found that the simulated indoor temperature is unstable when the measured temperatures fluctuate similarly for each day (indoor temperature.png). I just don't known what would contribute to this mismatch when they shared the same weather condition. 


Have anyone faced this problem before? any ideas to figure out this mismatch?


I will very appreciate for any helps!


Regards,
Zhichen
