Height vs SubCooling vs Freon Charge
KindaSorta ,On a 90* day , how much SC do I need for each 10' (per floor) of rise? . Is there a chart for knowing how much liquid Freon "backs up "in the cond coil, as the vertical rise goes beyond the Factory lineset length of 15' by todays standard,and 25' by yesteryears standard. At the moment I don't know how much extra Freon to put into a system to compensate for the increase of SC along w/ an increase in the # of passes of tubing in the cond coil that fill up w/ liquid Freon.. So, this is why I charge a system to a full LL at the TXV , and then I get to see what SC comes w/ a full charge.I think. Name plate SC is not for every job ,I think.
