| Abstract: | New technology of siphon off water is adopted in our country for the first time. A high efficiency_siphoning mode evacuated_tube solar hot water collector has been developed successfully. It has the properties of high efficiency, lower loss coefficient, prolonged use in a full year and basically balanced amount in four seasons. The effective heat removal factor F c is increased. A specially designed light gathering reflecting board under the evacuated_tuber together with the surface reflective mirror increase thermal efficiency at noonday, making the instantaneous efficiency steady in almost one day. Compared with ordinary evacuated_tuber solar hot water collector, its daily thermal efficiency increases by 15% or more. |
