摘要: Abstract This paper presents an experimental comparative performance study between a storage solar domestic hot water system and conventional one. The differs from the one by integrating collector tank into piece of equipment. investigated consists six 80-mm-outside diameter copper tubes connected in series to act as absorber tank. Tests under different flow patterns are conducted simulate consumption. overall heat loss coefficient, useful gain, instantaneous efficiency, efficiency factor, removal factor temperature distribution along pipe determined using modified equations derived for basic derivation Hottel–Bliss–Whillier. A comparison theoretical results showed good agreements that two systems superiority system.
