Abstract

Although solar collectors have been available for many years, there is continuing interest in their development and optimization using mathematical analysis, especially for various operating condition and situation. Component failures and system performance degradation in solar water heaters due to scaling are common in areas of hard water. Scaling tendency and its effect on various key parameters like instantaneous efficiency, overall heat loss coefficient, mass flow rate and heat transfer rate are discussed for a ten parallely connected forced convection collector array. Changes in constants of Hottel Whillier Bliss (H-W-B) equation for the different scale thickness are brought out. Various scale prevention methods are discussed and concluded that even though many descaling techniques are presently available for the solar water heaters, there is a need for technology development.
