The scope of the investigation is to validate the combined functioning of double phase thermosyphon –soil-atmosphere in arctic area. In this area permafrost phases the considerable amount of problem on account of geometrical consideration with moisture. Defrosting process helps to reduce volume and irregular foundation. In order to overcome this two phase vertical type thermosyphons are introduced. It transfer low temperature with moisture from atmosphere to the ground surface without consumption of power. Here an attempt is made to develop a mathematical model for average film thickness of refrigerant available on all inner portion of the thermosyphon such as over and underground heat insulated pipe , evaporator etc. Mathematical analysis and study predicts that the resistance of refrigerants have been two times lesser then the condenser. Thus the experimental calculations of soil temperature at different regime made possible without consideration of refrigerant film thickness. The relation for solar radiation components for condenser and over ground pipe is developed. A comparative analysis of two models of system double phase thermosyphon – soil – atmosphere predicts that the introduced model lowers the freezing radius the maximal distance in between thermosyphons is about 18.6 %.
