초록
This paper deals with the design, construction and operation of a direct solar hot water heating system developed to harness the solar energy more effectively. The system introduced here uses a unique network of riser tubes and header pipes apart from the existing concept to exploit the physical properties of water which expands when it freezes. It also employs a special pressure relief mechanism for the header to prevent its breakage due to freezing. A number of tests are made to assure its functional reliability during frigid weather conditions and its superior performance over indirect systems.
