Abstract
An OTS is more convenient to use and provides better temperature-contr olled water than a natural circulation system. An excellent way to con trol the exit-water temperature of an OTS is to utilize a PCTCV. Our r esults show how the average water temperature changes with insolation and collector inclination angle. The measured collector efficiency is close to 60%, while the overall efficiency for the system including th e storage tank is relatively low due to poor thermal insulation and la rge heat capacity of the storage tank. Calculated results agree with e xperimental measurements. (C) 1998 Elsevier Science Ltd. All rights re served.
