Appendix G220.127.116.11 of ASHRAE 90.1-2007 gives the formula for systems 1
& 2:Pfan = CFMs x 0.3where CFMs is the supply fan airflow rate in
cfm and Pfan is in watts. I just noticed that in SI version, the
formula is the same Pfan = CFMs x 0.3 where Pfan is also in watts but
CFMs is in lps. Which is version correct? I have already looked into the erratas and addendum but did not find any corrections.
Thank you all in advance.
