Novel tool and guidelines for ground source heat pumps in densely populated areas: a Swedish project
(International Ground Source Heat Pump Association, 2022)
With one system installed for every twenty inhabitants, Sweden is by far the country with the highest penetration of Ground Source Heat Pumps (GSHPs). Unsurprisingly, it has initiated a project to support designers and ...
Impacts of prospective LEED building's energy loads on a borehole heat exchanger: A case study in Central Illinois
(International Ground Source Heat Pump Association, 2022)
Assessing the thermal behavior in the subsurface surroundings of a borehole heat exchanger (BHE) is necessary for evaluating the performance of GSHP systems. In this study we undertook a preliminary thermal analysis on a ...
Experimental performance analysis of a dual source heat pump integrated with thermal energy storage
(International Ground Source Heat Pump Association, 2022)
To mitigate disturbances to the electric grid resulting from the growing penetration of intermittent and decentralized renewable generation, a dual-source (air source and ground source) heat pump (DSHP) integrated with ...
Accuracy of analytical approaches to thermal response test interpretation
(International Ground Source Heat Pump Association, 2022)
Thermal conductivity obtained via thermal response test (TRT) is one of the essential parameters for the design of shallow geothermal systems, especially a borehole heat exchanger (BHE). During TRT analysis, several factors ...
Climate change effects on the energy performance of a residential groundsource heat pump system
(International Ground Source Heat Pump Association, 2022)
The objective of this paper is to examine the impact of climate change on the energy performance of a typical residential ground-source heat pump (GSHP) system equipped with a horizontal ground heat exchanger (GHE) and ...
Technical and economic evaluation of a ground source heat pump with thermal and battery energy storage systems for residential dwellings in Quebec
(International Ground Source Heat Pump Association, 2022)
Ground source heat pump (GSHP) systems have been identified as promising solutions to help buildings achieve future carbon neutral targets. However, two main barriers decelerate the wide adoption of this technology in every ...
Investigation of design and control strategies for combining Photovoltaic Thermal (PVT) solar modules with ground-source heat pump systems: Case example for net zero building in a moderately cold climate
(International Ground Source Heat Pump Association, 2022)
A synergistic coupling of a ground source heat pump (GSHP) system with photovoltaic thermal (PVT) modules for a cooling dominated net-zero building in a moderately cold climate is presented in this study. As individual ...
Uncertainty assessment of the hydraulics properties surrounding a standing column well with a thermal response test
(International Ground Source Heat Pump Association, 2022)
The standing column well (SCW) is known for being a highly efficient ground heat exchanger as it relies on both conduction and advection heat transfer processes. Therefore, the interpretation of a thermal response test ...
Long-term GSHP system performance measurement in the USA and Europe
(International Ground Source Heat Pump Association, 2022)
This paper presents an overview of the International Energy Agency (IEA) technology collaboration program Heat Pumping Technologies (HPT) Annex 52, "Long term performance measurement of ground source heat pump (GSHP) systems ...
Open library of g-functions for 34,321 configurations
(International Ground Source Heat Pump Association, 2022)
Thermal response functions, known as g-functions, are commonly used in ground heat exchanger design tools and whole building energy simulation programs to simulate the ground heat exchanger performance. Calculation of ...
