Analysis of retrofit air source heat pump performance : results from detailed simulations and comparison to field trial data [PDF]
, 2011 In the UK, gas boilers are the predominant energy source for heating in housing, due primarily to the ready availability of natural gas. The take-up of heat pumps has lagged far behind Europe and North America.

Energy Efficiency Technologies – Air Source Heat Pump vs. Ground Source Heat Pump
Journal of Sustainable Development, 2009 Heat pump deserves the name of eco-innovation. It uses ‘free energy’ - warmth collected in the soil or in the air to provide heat ing and cooling. There are two main types of heat pumps – air source heat pump and ground source heat pump. How do they work? What are the benefits of each system? How do they compare?

THE SCOP OF AN AIR SOURCE HEAT PUMP: COMPARISON BETWEEN ON-OFF AND INVERTER HEAT PUMP
JP Journal of Heat and Mass Transfer, 2021 The paper investigates the seasonal performance of electric air-to-water heat pump comparing an on-off heat pump with an inverter-driven variable speed compressor. Reference is made to a heat pump for domestic space heating installed in Bologna, and the bin-method proposed by UNI/TS 11300-4 is employed in order to investigate the effect of external ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
