[TRNSYS-users] TRNSYS ERROR TOLERANCE

[王洋]

Dear all,

I have some questions about TRNSYS ERROR TOLERANCE:

1) Whether there is a Temperature Sensor in TRNSYS? If so, e.g. What's the
range of the error(difference) between this TRNSYS' the temperature Tair and
the actual situation?( e.g. the actual indoor air temperature is 20°C in the
room, maybe TRNSYS's Temperature Sensor measuring result is 19.99°C etc.  )
If not, how does TRNSYS measure the temperature such as Tair, Top? Or how to
get these temperatures' value?
2) like 1),What's the range of the error(difference) between the Ideal
Heating's QHEAT after running in TRNSYS and the actual heating's QHEAT? i.e.
What's Max. and Min. error(difference) range?

Many thanks!

Br.
