Dear all,

     I have a question about room air temperature: NTYPE 1: TAIR. As we
know, there are different room air temperature in different height of one
room. Besides that,  the wall, the floor and roof temperature of the room
are also not the same. Please tell me  what's meaning of NTYPE 1: TAIR?
Where is This AIRNODE? How to define This AIRNODE?

 PLUS: to Operative(operation) temperature of room:  How to define
it?  What' meaning is  Operative(operation)temperature of room? What's
difference of Operative(operation) temperature of room and  NTYPE 1: TAIR?


Many thanks!

Br.

wang
