A new theoretical approach to determine the air outlet temperature of an air-to-ground heat exchanger [PDF]

open access: yesMethodsX
In this study, the control volume method is used to determine the air temperature at the outlet of an air-to-ground heat exchanger. Its implementation consists in dividing the duct of the ground-air heat exchanger into micro-volumes of identical size. An

Shared ground heat exchange for the decarbonisation of heat [PDF]

open access: yes, 2022
Shared ground heat exchange can deliver low-carbon electrified heat where individual heat pumps or heat networks are not feasible, such as in terraced homes. However, there is a policy gap around these mid-scale heat solutions. We outline the benefits and challenges of shared ground heat exchange, and actions needed by policy, housing, and innovation ...
