Dear Karol, just a brief answer: 1.)
The parameters of Type are defined in the Trnsys Studio at the Tab
parameter 2.)
The two NTYPEs are the same if NTYPE 24: For being backwards compatible it is always calculated by DO
NS=N1,N2 ! all surfaces of airnode OUT(IOUT)=OUT(IOUT)+AREA(NS)*TSI(NS) TOTAREA=TOTAREA+AREA(NS) ENDDO
OUT(IOUT)=OUT(IOUT)/TOTAREA NTYPE 120: a) Longwave radiation mode = STANDARD: TMSURF=TMSURF+AREA(NS)*TSI(NS) TOTAREA=TOTAREA+AREA(NS) ENDDO OUT(IOUT)=TMSURF/TOTAREA
!area weighted mean surface
temperature b) Longwave
radiation mode = DETAILED: and the therewith the position in the
room with respect to the surrounding surfaces. Best, Von: Karol Bandurski
[mailto:karol.bandurski@put.poznan.pl] 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:
and
The first is calculate according to surface area, and
second is calculate according to surface area and distance from person? Kind regards, ------------------------------------------------ Karol Bandurski MSc. Institute
