Scientists led by China’s Dongguan University of Technology have proposed a novel control approach for water-to-water heat pumps that uses carbon dioxide (CO2) as refrigerant. The model-based optimal ...

These are the best whole-house heat pumps from Consumer Reports' tests. These heat pumps are more efficient and can save you money.

Researchers at Brunel University London have developed a new system design for residential heat pumps using transcritical carbon dioxide (CO2) as the refrigerant. CO2 has a very low boiling point and ...

CO2 heat pumps represent a promising future for cooling and heating. These systems use carbon dioxide as a refrigerant, providing an energy-efficient solution that can warm your home while heating ...

Heat pumps can reduce carbon emissions associated with heating buildings, and many states have set aggressive targets to ...

From Japan to China and the US to Scandinavia, heating with air conditioning has long been standard practice. Some 2.3 million new heat pumps were installed in Europe in 2024, with 40% of these made ...

Sales of super-efficient electric heat pumps are rising, now overtaking sales of gas furnaces in the U.S. But what are heat pumps? And why do some call them a key climate solution? Here are the ...

The name "heat pump" is a bit of a misnomer, says Kevin Kircher, assistant professor of mechanical engineering at Purdue University who works with the Center for High Performance Buildings. "A lot of ...
