[TRNSYS-users] mean radiant and operative temperature

[Karol Bandurski]

Dear All,

 

I have 2 question:

 

1)      In manual vol. 5 (introduction) I have read:

 

The third parameter gives the WEIGHTING FACTOR between air and mean surface
temperature for the calculation of an operative room temperature. The inputs
and outputs of TYPE 56 depend upon the building description and options
within the TRNBUILD program. TRNBUILD generates an information file
describing the outputs and required inputs of TYPE 56.

 

Where can I found/ set this factor?

 

2)      What is the exactly difference between:


NTYPE 24 

TMSURF 

weighted mean surface temperature of airnode 

[°C] 

and


NTYPE 120 

TMRLW 

Mean radiant temperature (longwave only) 

[!C] 

 

The first is calculate according to surface area, and second is calculate
according to surface area and distance from person?

 

Kind regards,
