| Abstract |
A feasibility study of a district hybrid geothermal heat pump system serving a newly planned, sustainable subdivision in a subarctic climate in Northern Canada is presented. The study examines the technical and economic feasibility of constructing the district heating system with a low-temperature fluid supply loop serving distributed geothermal heat pumps in buildings. The heating loads are met by an integrated combination of a ground heat exchanger (mainly acting as a thermal storage device), solar thermal collector arrays, a sewer heat recovery system, and a peaking boiler system. A parametric analysis of 50-year life-cycle cost is used to identify the most feasible options. |
