Advances in heat pump systems: A review
TL;DR: In this paper, the authors provide an update on recent developments in heat pump systems, and is intended to be a "one-stop" archive of known practical heat pump solutions.
Journal ArticleDOI
Ground-source heat pumps systems and applications
TL;DR: A detailed literature-based review of ground-source heat pump technology, concentrating on loops, ground systems, and looks more briefly at applications and costs and benefits is provided in this paper. But, despite potential environmental problems, geothermal heat pumps pose little if any serious environmental risk when best management practices are applied during the installation, operation, and decommissioning of these systems.
