Title (EN) MULTI-CHANNEL GROUND HEAT EXCHANGE UNIT AND GEOTHERMAL SYSTEM
(FR) UNITÉ D'ÉCHANGE DE CHALEUR AU SOL À CANAUX MULTIPLES ET SYSTÈME GÉOTHERMIQUE
Abstract:
(EN) Geothermal energy is increasingly recognized as a useful energy source for both industrial and residential purposes. Disclosed herein are units for subterranean heat exchange comprising a polymer block with 'mini-channels' adapted and / or sized for highly efficient heat exchange. In some embodiments such units can, as needed, be manufactured off site, spooled for transport, and conveniently installed in boreholes. Other arrangements are also described for conduits located within a borehole for heat exchange, without a polymer block. Also disclosed are geothermal heat exchange systems including those that employ such units, for example with direct expansion of a two-phase heat-exchange fluid such as carbon dioxide.
(FR) L'énergie géothermique est de plus en plus reconnue comme une source d'énergie utile à des fins industrielles et résidentielles. L'invention concerne des unités pour un échange de chaleur souterrain comprenant un bloc polymère comprenant des "mini-canaux" adaptés et/ou dimensionnés pour un échange de chaleur hautement efficace. Dans certains modes de réalisation, de telles unités peuvent, selon les besoins, être fabriquées hors site, enroulées pour le transport et installées de manière appropriée dans des trous de sonde. D'autres agencements sont également décrits pour des conduits situés à l'intérieur d'un trou de sonde pour un échange de chaleur sans bloc polymère. L'invention concerne également des systèmes d'échange de chaleur géothermiques comprenant ceux qui utilisent de telles unités, par exemple avec une expansion directe d'un fluide d'échange de chaleur à deux phases tel que le dioxyde de carbone.
