I've done a couple of Load Calcs (practice) for homes with Heat Pumps and want to make sure I'm doing this correctly. The only question I have is regarding the Heat Pump. I think the rest of the calcs I have down. I've attached 2 pics (Name Plates) of the Inside FAU and the Outside Compressor for the exact reference to numbers. I"m only focusing on the Heating load since that is larger than the cooling in this case.
Calculations Follow:
Outside Unit has a compressor and fan. From the Name Plate the VA I'll use is: 7314 VA (31.8X230)
Inside Unit has a fan and a Heat Strip. The heat strip is 5kw. FAU Minimum Ampacity is 7.5amps/230 volts. Gives 1725 VA (7.5X230) Plus 5000 VA for heat strips.
So the Total Heating Load is 7314 VA + 1725 VA + 5000 VA = 14,039 VA.
Did I take the correct numbers from the name plate....logic correct? Thanks for your input!
