Thermal performance estimation and optimisation of a shallow geothermal compound heat pumping system for combined process heating and cooling

The present study proposes a unique thermal loop assembly, between a ground-source vapour compression cycle and an absorption heat pump, for combined heating and cooling production. The feasibility of the setup is conducted through a, data-driven, thermal modelling approach. This is complemented by...
