Résumé

Ground coupled heat pump sytems, composed of a ground heat exchangers and a heat pump are an efficient and environmentally friendly technology to cool and heat building. Heat exchangers are one expensive component of the systems. Borehole thermal resistance, which is the ability of the ground heat exchanger to resist heat transfer, is one of the parameters considered in the determination of the heat exchanger length. Versaprofiles, a Canadian company, has developed a thermally enhanced pipe to reduce the borehole thermal resistance, and consequently the borehole length, another expensive component of the system. In situ estimation of borehole thermal properties of enhanced and standard pipe made at Blake Group facility allowed in this work to evaluate the potential borehole length saving provided by the enhanced pipe. In a second step, the experimental data was used to predict the system performance through analytical simulations and assess the benefits of the thermally enhanced pipe over the standard system commonly used.
