Definitions

  • the present invention relates to a special tube for an underground heat exchanger, and more particularly to a special tube for a underground heat exchanger of a plum-shaped spiral ground source heat pump.
  • the conventional ground source heat pump buried pipe adopts a round PE pipe, and its cross section is circular; in order to achieve turbulent flow in the pipe, the flowing water V > 0.4 m / s, generally takes 0. 6m / s, the flow rate is fast to form Turbulent flow, but this increases the energy consumption of the circulating water pump.

Abstract

La présente invention porte sur un tuyau spiralé en forme de fleur de prunier utilisé spécifiquement avec des échangeurs de chaleur souterrains de pompes géothermiques, lequel tuyau comprend une paroi de tuyau (1) et un orifice de tuyau (2). Les sections transversales de ladite paroi de tuyau (1) et dudit orifice de tuyau (2) prennent la forme d'une fleur de prunier, tandis que leurs surfaces prennent une forme spiralée de fleur de prunier. Les bords des sections transversales en forme de fleur de prunier de la paroi de tuyau et de l'orifice de tuyau sont formés par un arc de rayon R-1 et un arc de rayon R-2, respectivement. R-1 vaut 6 mm, et R-2 vaut 3 mm. Le diamètre maximal D de la paroi de tuyau (1) est de 32 mm, le diamètre maximal d de l'orifice de tuyau (2) est de 26 mm, et l'épaisseur de la paroi de tuyau (1) est de 3 mm. Le matériau constitutif du corps du tuyau est du polypropylène ou du polyéthylène haute densité. La structure selon l'invention permet au milieu s'écoulant à l'intérieur d'atteindre rapidement l'état turbulent, de façon à améliorer efficacement la quantité de chaleur transférée. Le rendement d'échange de chaleur d'échangeurs de chaleur souterrains de systèmes de climatisation à pompe géothermique se trouve amélioré, la quantité de tuyaux enfouis par forage extérieur est réduite de 10 % à 15 %, et une économie est faite sur l'investissement technologique initial.
