Thermosyphon utilizing vapor bubble pumping, which can realize the heat transfer without requiring the outside power, has been studied intensively. However, some problems have been left for the practical application. Especially, it has been clarified that the heat transfer, that is, the circulation of working fluid becomes intermittent in the condition with small solar heat in morning and evening by the demonstration experiment using model house installed in outdoor. Then, a control system of thermosyphon system for realizing the stable heat transfer, namely almost constant flow rate of working fluid is proposed. An analytical model is required in order to develop a control system. In this report, an analytical model for the experimental equipment of thermosyphon utilizing vapor bubble pumping is discussed.
