ABSTRACT

A new kind of two-phase reverse thermosyphon with liquid water as a heat carrier and with vapor of refrigerant as a pumping agent will be presented in this paper. The best properties of each work agent are used in this case. In particular, water and its solutions has the best properties as a heat carrier, and refrigerants keep pressure above the atmospheric pressure inside of devices if the temperature lies in the range from 0 to 100°C. It considerably improves the operating characteristics of the device and allows elimination of the mechanical transporting pump out of the loop with circulation directed opposite the natural convection. The main news consists of adding a second work agent and performing heat carrying and pumping of the heat carrier with the help of two different work agents. A few copies of the two-phase reverse thermosyphon loop with two work agents were successfully tested under laboratory conditions and in combination with an experimental solar installation.
