Addressing the growing concerns of climate change necessitates the decarbonisation of
energy sectors globally. Heating is the largest energy end-use, accounting for almost half of …

In this paper, a comprehensive review is performed on hybrid systems using electrical Heat
Pumps for Heating, Ventilation & Air Conditioning systems and Domestic Hot Water …

We present new formulations of the 'energy hub'model and evaluate their performance. The
energy hub model consists of a mixed-integer linear programming problem that balances …

Hybrid heat pump systems are a suitable solution to mitigate the well-known disadvantages
of air-source heat pumps, such as energy losses linked to defrost cycles and a significant …

Air to water electric heat pumps are one technological solution to achieve energy
defossilisation goals for heating of residential building stock. Nevertheless, they may not …

Decarbonisation of the electricity system requires significant and continued investment in
low-carbon energy sources and electrification of the heat and transport sectors. With …

The interaction between electricity and heat systems will play an important role in facilitating
the cost effective transition to a low carbon energy system with high penetration of …

Integrating gas, electricity and residential heating sectors through hybrid heating
technologies equipped with smart controls could provide energy system planning and …

High-efficiency domestic hot water (DHW) production has gained more attention currently,
and a modified transcritical CO 2 ejector enhanced two-stage compression cycle (METC) for …

A numerical model for the calculation of the seasonal performance of different kinds of
electric air-to-water heat pumps is presented. The model is based on the procedure …
