(15C) Solar Pool-Heater Sizing

[SlideRule]

An extract from Appendix F - Calculator and Computer Programs of Designing & Installing Solar Commercial Pool Heating Systems

… calculator programs in Appendix F may be used to rate collectors which first order thermal performance equations are available. Appropriate monthly pool temperatures, (Ti), ambient temperatures (Ta) and insolation rates for specific months and locations may be entered in programs as indicated and non-standard day ratings similiar to FSEC standard day ratings calculated … Program "A" for the HP 15 C is basically identical to that which FSEC uses to rate collectors for standard Florida day conditions except that it makes use of first order rather than second order thermal performance equations. The shorter "looped" programs yield results which are within one percent or so of the longer version. They require slightly longer running time on the calculators but are far easier to enter and de-bug …
