Long-Term Performance Measurement and Analysis of a Small-Scale Ground Source Heat Pump System
Energies, 2020 Recent data suggest that heat pumps, despite having the potential to cover over 90% of the global space and water heating demands, only provide less than 5% of global heating.

Heat Kernel and Moduli Space [PDF]
Mathematical Research Letters, 1996 The author describes a proof of the formulas of \textit{E. Witten} [Commun. Math. Phys. 141, No. 1, 153-209 (1991; Zbl 0762.53063); J. Geom. Phys. 9, No. 4, 303-368 (1992; Zbl 0768.53042)] about the symplectic volumes and the intersection numbers of the moduli spaces of principal bundles on a compact Riemann surface.

Applying Solar PV to Heat Pump and Storage Technologies in Australian Houses
Energies, 2021 Innovative mechanical services coupled with renewable energy systems are crucial for achieving a net zero energy goal for houses. Conventional systems tend to be vastly oversized because they lack the means to buffer energy flows and are based on peak ...
