LOOP THERMOSYPHON HEAT PIPE COLLECTOR WITH THERMAL STORAGE

摘要

Availability of solar energy is of fluctuating nature. Flat plate collectors used for harnessing this energy have many limitations. Its efficiency is also low , bulky size and no output is obtained during off sunshine hours these are the main reasons why the flat plate collectors are not so popular. To enhance the performance of collector heat pipe can be used in simple flat plate collectors to get the advantage of latent heat transport and also to get uninterrupted output with extended period after the sunshine hours, Thermal Energy Storage unit can be used. So in order to overcome the above limitations the Experimental set up is designed and developed with thermosyphon loop heat pipe with integrated Thermal Energy Storage unit which is placed on the back side of the absorber plate to the conventional flat plate collector.TES unit collector gives extended output of 4 to 5 hrs after the sunshine hours. The collector can meet the daily domestic and industrial requirement of water heating.
