INVESTIGATION OF THE INFLUENCE OF THE CAPILLARY STRUCTURE OF A THERMOSIPHON ON ITS THERMAL POWER WITH HEAT CARRIERS R134a, R410a, R407c

Thermosiphon (TC) is an evaporative-condensing heat exchange device, where the circulation of working fluid (intermediate coolant) carried out due to gravitational forces. There no porous wick in thermosiphons, it replaced by grooves various geometric shapes. Structurally, thermosiphons are made form hermetically sealed and elongated cylindrical vessels, inner volume which filled with a fluid. Liquid carriers used as fluid, can perform aggregate-phase transition at operating temperatures observed during operation recuperative exchanger. In this article, author talking about comparing limits thermal power ventilation air conditioning systems. At same time, use freons R134a, R410a, R407c medium, capillary structure represented following types: Ω –shaped groove, rectangular groove triangular groove. For comparison, thermosiphon outer diameter 8 mm used. The dependences on temperature for all types limitations transfer capacity presented, depending analysis best when using body out.
