Foundation piles have the potential to improve economic and technical feasibility of ground source heat pump (GSHP) systems. They simultaneously provide structural support energy for space heating cooling. In this study, a thoroughly verified validated numerical model novel in-ground exchanger GSHP systems is developed used simulate optimize performance. Commercially available helical steel cas...

In this research, a combination of passive and active methods is used to design a nearly zero energy building in four major climatic regions of Iran, including cold, mild, dry-warm, and wet-warm ones. The annual energy consumption analysis is performed using DesignBuilder® software. The passive strategies include Trombe Wall, blue roof, and thermochromic windows, and the active methods are usin...

This article provides plain and handy expressions to decide the most suitable analytical model for the thermal analysis of the ground source in vertical ground-coupled heat pump applications. We perform a comprehensive dimensionless analysis of the reciprocal deviation among the classical infinite, finite, linear and cylindrical heat source models in purely conductive media. Besides, we complet...

A comprehensive numerical investigation of long-term operation Ground-Sourced Heat Pumps through Borehole Exchangers is presented. Thermal fluxes between systems are analyzed a semi-analytical method based on line source models. Operation points geothermal and backup determined by an hourly-based non-linear constrained optimization. Simulations 12-buildings neighborhood demonstrated that middle...
