A Simple Mathematical Model for Evaluating the Effectiveness of Solar Water Heating System with Thermosyphon Heat Exchanger

Authors: A.Srinivas, S. Venkataiah

A simple mathematical model for estimating energy transfer in a solar hot water tank fitted with thermosyphon heat exchanger and operating in a thermosyphon loop is developed. The model is used for evaluating the effectiveness of the heat exchanger operating under different mass flow rates. An experimental test facility for the heat exchanger is fabricated in which an electric geyser is used for hot water supply. Comparison of experimental results with the theoretical results yielded the effectiveness of the heat exchanger. It is found to vary between 0.7 to 1.0 for the normal range of flow rates encountered in a thermosphon solar water heating system.
