An Integrated Collector Storage Solar Water Heater and Study of its Temperature Stratification

Abstract

In this paper we describe an integrated collector storage solar water heater for the North Western region of India for use as domestic water heater during the winter season and present the experimental results of temperature stratification. The system consists of a steel water storage tank with azimuthal orientation such that its walls face south east, south west, north east and North West directions. The sunlit walls (south east and south west) and the top cover surface of the storage tank are covered with transparent insulation material (TIM) and the off-sunlit sides with opaque insulation. Experimental results show that the top layer is at the highest temperature. The top layer is drained using a new design of the outlet. The system can be used in rural areas or as a pre heater in more affluent households. The system can return the cost of conversion of the storage tank into a Solar Water Heater in one winter season by saving the cost of electrical energy required for heating water during winter months.

Assessment the Performance of the Triangular Integrated Collector

“…(10) shows the effect of the barrier on the maximum temperature at the top of the collector. As shown, the maximum temperature was at 2 p.m. and reduced at the end of the operation period (Mozumder, 2013). Fig.…”

The Various Designs of Storage Solar Collectors: A Review

“…The thermal efficiency of the new design, about 50%, is comparable with classical storage solar collectors. Mozumder (2013) presented another design for the storage solar collectors in the form of a cube, the south east, south west, and upper sides of the cube are covered with an overlay cover to increase heat gain. Other studies have been conducted to improve and achieve the performance of solar collector heater systems, such as (Soponronnarit et al 1994;Currie et al, 2008).…”
