Parametric modelling of domestic air-source heat pumps [PDF]
Energy and Buildings, 2017 A new domestic air-source heat pump model is proposed which can be parameterised either from field data, experimental data or manufacturers’ standard rating data. The model differs from the much more prevalent system-side regression models for these types of heat pumps in that it operates on refrigerant-side variables.

Innovative Process Integrating Air Source Heat Pumps and Direct Air Capture Processes
Industrial & Engineering Chemistry Research, 2022 Most integrated assessment models indicate a need for technological carbon dioxide removal from the atmosphere to achieve climate mitigation targets. Currently, direct air capture (DAC) appears to be one the “backstop” technologies suitable to provide this service.
