Analysis of collector array performance from field derived measurements
The Hottel-Whillier-Bliss (HWB) equation hs been the standard tool for evaluation of collector thermal performance for many years. A technique is presented here which applies the criteria of ASHRAE Standard 93-77 to the determination of the HWB equation coefficients using measured performance of actual collector arrays in a field environment. Results of the analysis of an example collector array illustrate the technique. Finally, preliminary results of the analysis of a number of collector designs are presented.
