THERMOSYPHON SOLAR WATER HEATERS: EFFECT OF STORAGE TANK VOLUME AND CONFIGURATION ON EFFICIENCY

摘要

A thermosyphon solar water heater SWH is simulated using the TRNSYS program. The effect of the hot water storage tank volume and configuration on efficiency is investigated in this paper. The efficiency of the system can be improved by employing larger storage tanks. Horizontal and vertical storage tanks give similar efficiencies and useful solar heat. The performance of the SWH is better described by the supplied heat to the load rather than the gained useful solar energy.
