Hi all, I'm revising for commercial gas exams and am getting little confused over working out ventilation for a gas boiler house containing commercial gas boilers.
I am using IGEM/UO/10 EDITION 4 using pages 22, 23, 24.
Page 22 shows ventilation should be calculated as follows.
low level: 4cm2 per total kw net heat input
high level: 2cm2 per total kw net heat input
page 23 shows ventilation with louvered doors.
I'm I right in reading that the from ground level the 1st 1 x meter from the floor up should only be used in the calculation for low ventilation?
If the same Louvre doors are above the 85% of the top of the building then this also would be used as high ventilation?
Now the confusion:
Page 23 shows low level ducted air and gives a table showing table one with higher figures to be used when calculating high and low ventilation required per kw input?
Well confused????
Could someone please explain the above, having a mental block.. Thanks in advance
