Re: [TRNSYS-users] what's the difference between operative zone temperature and air temperature of zone?

[Adrien JEZEQUEL <a.jezequel@itf.biz>]

Dear Yuyun,

Top is a sort of average between air and surface temperature. Top is 
calculated as shown below :

Top = Aop * Tair + (1 - Aop)*Tsurf         
Where Aop is a weighting factor for operative room temperature

So Top is a little bit different from Tair, but this seems to be more 
accurate if you want to observe thermal comfort into a room.

Kind regards, Adrien
