Abstract
Solar thermosyphon can transport heat without using additional power input. We built up an experimental set up of solar thermosyphon on a model house. The working fluid, water, is heated by solar irradiation in the thermal collector on the roof of the model house. The heat is transported to the heat exchanger which is set 4m lower than the thermal collector. In this paper we examined the influence of check valve and city water flow rate on operating characteristics of solar thermosyphon.
