|Abstract: ||In this thesis the investigation of the possible use of solar energy for large scale water
heating system is conducted for the following sites in Ethiopia: Addis Ababa Tannery,
Dire Tannery, Modjo Tannery, and Jimma Hospital.
The thesis focuses on simulation of large-scale solar water heating system and its
economic analysis. Transient performance of the system is computed using a numerical
heat transfer model of a single glass cover flat plate collector solar water heater with riser
and header type active system. The various design parameters are gathered from the
inside country solar water heater manufacturers and dealer companies and also from the
world experience. The meteorological data for simulation was prepared by taking the
average of five years starting from 2001 - 2005.
From the annual contribution of solar energy to the heating load and the estimated
investment cost, the unit solar energy cost and the pay back period of the system for each
case were calculated.
The result obtained indicates that the unit solar energy cost for all cases are less than that
of unit cost of fuel heating. Hence the solar energy is the viable alternative source of
energy for large-scale water heating systems in Ethiopia.|
