The advantage of running a direct expansion CO₂ heat pump with solar-and-air simultaneous heat sources: experimental and numerical investigation

Dual-source solar-air heat pumps represent a promising solution for overcoming the limitations associated with single-source utilization, thereby enhancing heat pump performance. However, running the heat pump by alternatively employing the more advantageous source requires the integration of a controller capable of continuously monitoring...

Optimisation of a Photovoltaic-Thermal (PV-T) panel for Desalination

Water stress levels are rising due to industrialisation and the increase in population. With the freshwater supplies depleting at a rate faster than the refreshment rate, there is a need to look into unconventional and sustainable sources of water. Desalination technology is a reliable solution for the future water requirement; however, it is an...

Thermal and Electric Performance of PV/T Solar Chimney System

The residential and service sectors are responsible for the 39% of the total energy consumption. 80% of this energy is used for heating purposes. Achieving nearly zero energy buildings is a major goal for the near future. The design of an integrated electrical and thermal system can substantially help to reach such objective. The façade is the...
