Design of thermosyphon foundations
WebNov 9, 2012 · Abstract. This paper describes the general thermal design concept and considerations for the design of a heated, on-grade shallow building foundation on thaw-unstable ground in permafrost regions. Three kinds of foundation cooling systems are discussed. These include the thermosyphon system, ventilated duct system, and heat … WebDifferent designs of THTDs are described in this chapter. The simplest THTD has a tube-in-tube construction which can become unstable for certain operating conditions. A THTD with a crossover device is more stable. Their applications in nuclear and solar energy are described in detail.
