EFFECT OF HOT-WATER CONSUMPTION ON TEMPERATURE DISTRIBUTION IN A HORIZONTAL SOLAR WATER STORAGE TANK

This experimental investigation assesses the behaviour of a solar wate r heater provided with a liquid heat exchanger in a horizontal storage tank. The factors that affect the stratification inside the storage t ank are considered. The performance of the system is studied in the li ght of the daily consumption of hot water of an Egyptian family. The r esults obtained show that in the places where it is necessary to use a horizontal tank it must be supplied with an auxiliary electric healer to meet the required load at the required temperature, especially in winter.
