Abstract:
A solar water heater was designed and constructed using
locally available materials. The components of the system are flat
plate collector and storage tank. A method of estimating the
performance of solar water heater circulating to a storage tank by
thermosyphon is presented. Ideal condition of no draw off during
the day and clear sunshine are assumed. An experimental study
performed on the system shows that the system perform well with
approximately 50.1% collector efficiency using Hottel - whiller
equation (ASHARE 93-97 standard test method) and producing hot
water at average temperature of 550C. The results were compared
with those estimated from theoretical method. The results show
very good agreement.
