Estimation of Auxiliary Heat Consumption
SCALED SOLAR LOAD RATIO
F (VTn/DD) [alpha]
NLC/Ac + G
All parameters in this expression are defined and recorded on
Worksheets 2, 3, and 4.
The yearly heat-to-load ratio is obtained from the nomogram in
figure 23. Using the value of SLR* calculated above and the city
parameter a from Worksheet 5, one simply reads the heat-to-load
ratio off the vertical axis of the nomogram.
ANNUAL AUXILIARY HEAT REQUIREMENT
QA = (QA/QL)a (NLC + G [multiplied by] Ac) DDa
QA = 32.6 x 10
