System Adjustment template-SFP value
Posted: Thu Mar 10, 2011 10:10 am
Dear All,
I have a simple query regarding SFP (W/l/s) value which determines the Auxiliary Energy. I am working on hotel development where Fan coil units (FCU) are specified for the hotel guest bedrooms. Apparently i did receive a FCU schedule from the manufacturer and total numbers of FC-Units are about 110.
In the manufacturer schedule the average or overall SFP value based on 110 FCU is specified as 0.23 w/l/s. Based on manufacturing schedule information i prepared templates for guest bedrooms by choosing the FCU as NCM system in NCM systems wizard. I have assigned heating 89% , cooling 2.41 season efficiency and in system adjustments i have assigned 0.23 w/l/s value and end up less Auxiliary energy value.
My query is
Does the way i assigned is right or wrong and i believe that’s how we have to assign but someone would clarify me please. I would believe the SFP value 0.23w/l/s is for the FCU- NCM system rather than 0.23w/l/s value for Fresh air supply AHU SFP value?
Thanks in advance and reply would be appreciated
