Heating and Cooling with Ground-Source Heat Pumps in Moderate and Cold Climates, Two-Volume Set focuses on the use of very low-temperature geothermal energy for heating and cooling residential, institutional, and industrial buildings, and aims to increase the design community’s awareness and knowledge of the benefits, design, and installation requirements of commercial/institutional building ground-source heat pumps (GSHP). This set helps readers assess applicability, select a GSHP system type, and estimate building thermal load to ensure proper size for ground-source subsystems, appropriate brine and groundwater flow rates, and apt design of building closed-loops with distributed or central geothermal heat pumps.

The first volume addresses fundamentals and design principles of vertical and horizontal indirect and direct expansion closed-loop, as well as ground- and surface-water ground-source heat pump systems. It explains the thermodynamic aspects of mechanical and thermochemical compression cycles of geothermal heat pumps, as well as the energetic, economic, and environmental aspects associated with the use of ground-source heat pump systems for heating and cooling residential and commercial/institutional buildings in moderate and cold climates. The second volume focuses on applications and cases studies of ground-source heat pumps in moderate and cold climates. It details technical aspects, as well as the most common and uncommon application fields of basic system configurations. The principles of system integrations and applications in moderate and cold climates are also presented, each followed by case studies.

This comprehensive work is aimed at designers of HVAC systems, as well as geological, mechanical, and chemical engineers implementing environmentally-friendly heating and cooling technologies for buildings.
