Reducing energy consumption has its direct impact on the worldwide environmental status.
Smart energy processes must be adopted in order to enhance the reduction capacity of …

In this paper, a solar-driven heating and cooling system integrated with air source heat
pump is designed and applied to the ultra-low energy building. The heat and electricity from …

This paper studies the implementation of twin transition, ie, the combination of digital
technologies and European Green Deal goals, to achieve sustainable solutions supporting …

In cities, there are thousands of wastewater treatment plants. The treated tail water drained
from them is clean relatively, and has a stable flow rate. Extracting heat from it through tail …

As a compelling alternative to fossil fuel combustion, air-source heat pumps face challenges
in inefficiency, flammability, and pollution when operated at low ambient temperatures. To …

Decarbonizing the energy sector becomes a key topic to solving man-made climate change.
For achieving indoor thermal comfort conditions, conventional heating, ventilating, and air …

Electric (mechanical vapour-compression) heat pumps are acknowledged as a key
technology for heat decarbonisation, their role being evidently more significant than …

With the growing global demand for cooling, there is a critical need for sustainable solutions
that efficiently provide both heating and cooling. Fifth-generation district heating and cooling …

To improve the efficiency of HVAC system, a novel air-source heat pump based on the two-
stage compression cycle is proposed. The heat pump shows the multi-function of producing …
