Please give me a feedback if I have calculated right the Fan Power of the baseline building. Note that my baseline building requires an air heat recovery system (based on ASHRAE 90.1-2010) and that I have system 8.
Also according paragraph G220.127.116.11 and Table G18.104.22.168 my goal is to calculate the “A” at the equation CFMs*0.0013+A.
Also according Table 22.214.171.124A , “A” is related from Pressure Drop with derives from table 126.96.36.199.1B.
For the Pressure drop of the heat exchanger I choose from 188.8.131.52.1B “Energy Recovery Device other than Coil Runaround Loop” => (2.2x Energy Recovery Effectiveness) – 0.5 wc
In the given formula “(2.2x Energy Recovery Effectiveness) – 0.5” is meat by Energy Recovery Effectiveness the energy effectiveness of my building which is 70% or the energy effectiveness of the baseline building which is 50%?
I calculated with the Energy Recovery Effectiveness of MY building as following
Pressure drop = 2.2*0.7-0.5 =1.04 wc. Do you confirm this approach is right?
