Re: [TRNSYS-users] Tair/Top

[Richard Heimrath <heimrath@tugraz.at>]

Hello Davide,

the operative temperature includes the surrounding wall temperature

http://en.wikipedia.org/wiki/Operative_temperature

and also chapter 4.7.2 Trnsys Dokumentation:

The weighting factor for the operative room temperature. The operative room temperature is a function of both
the air and surface temperatures in the zone:
Top = Aop*Tair + (1-Aop)*Tsurf
(See manual for further information on equation)
This temperature is used most often in room comfort analysis simulations.

with sunny regards

Richard

Goodmorning,
can someone explain to me what is the difference between TAIR (air temperature of zone) and TOP (operative zone temperature) ?
Thanks in advance.
Best regards
