Ms. Sodha et al., EXPERIMENTAL PERFORMANCE OF BUILT-IN-STORAGE SOLAR WATER-HEATING SYSTEMS IN LABORATORY AND FIELD CONDITIONS, International journal of energy research, 21(3), 1997, pp. 275-287
Hourly thermal performance (both in laboratory and field conditions) o
f three designs of built-in-storage solar water heating systems of 100
litres capacity each has been reported. A different storage tank desi
gn is used in each of the three cases, Design I consists of three tank
s connected in series; in Design II, a parallelepipedic tank is divide
d into five zones with baffles; Design III is a simple parallelepipedi
c tank. The first two designs help in inducing thermal stratification
in the tank, It is seen from the results that the performance of Desig
n II is the best of the three. (C) 1997 by John Wiley & Sons.
