Does anyone have the calculation for determining the amount of Heat Extraction from a geo system? I have seen an old reference to the calculation being....."T-Delta X GPM X Brine", but I have no idea how to evaluate "brine" when I have a open loop fresh water water source. I am trying to evaluate the efficiency of my system and could use this calculation as a part of the toolbox. thanx,
500 is a constant arrived at as follows: 60 minute per hour X 8.333 Lbs per gallon X 1 btu per Lb per deg F The 500 changes a bit for loop fluids other than pure water, because the "sub constants" of 8.333 lb per gallon and 1 btu/lb-degF don't hold for other mixtures. All hours have 60 minutes, excepting the one at the end of which I've promised myself a beer. Hope that helps
