ANALYSIS OF AN INDUSTRIAL SOLAR HOT WATER SYSTEM.

Abstract

In this study, a large scale industrial hot water system at the CIAS 'Flight Kitchen', which caters for many of the airlines at the Singapore Changi Airport, is investigated. A computer simulation is carried out to evaluate the system performance and the cost effectiveness of such a system. The predicted values of the performance parameters agree well with the experimental results obtained. The contribution from solar energy towards the total energy demand remains high around 50% even under fairly poor weather conditions. The computer simulation indicates that the solar fraction is strongly dependent on the required temperature of hot water and with a temperature of 55 degree C almost all the energy requirement is provided by solar heating. The optimum storage capacity for water heating systems of this kind is estimated to be about 25 L-SCRIPT /m**2.
