Abstract
This paper presents an analysis of the performance of an inexpensive constant flow solar collector/storage system, which has been validated by experiments. the system consists of a network of pipes buried in the ground, the top surface of the ground being blackened by black board paint spray and suitably glazed. the heat can be extracted by flow of fluid in the pipes at a constant flow rate. It is seen that for a 7 cm depth of the plane of heat retrieval and 81/min flow rate of water, the collection efficiency of the system is 20.0 per cent. the efficiency increases with flow rate and decreases with the depth of the plane of heat retrieval.Keywords
