Heat pumps operate by moving heat from lower temperature areas to higher temperature areas. They typically take advantage of an electrically driven compressor and a closed vapor compression cycle.

Researchers in China proposed a solar-driven integrated system that combines reversible heat pump and organic Rankine cycle ...

People who rent their homes, or don’t have enough money to make major upgrades to their homes, have for many years been left ...

Researchers in Hong Kong have developed a hybrid-energy heat pump that seamlessly combines absorption and compression cycles using crystallization-free ionic liquids, improving efficiency and ...

Various heat pump technologies are examined from an environmental perspective using a life cycle assessment approach. The investigated heat pump systems utilize air, ground, and water as their energy ...

As the temperature lift increases, heat pump performance declines due to rising throttling losses in expansion valves. Ejectors present a promising alternative, enabling power recovery from the ...

Jon covers artificial intelligence. He previously led CNET's home energy and utilities category, with a focus on energy-saving advice, thermostats, and heating and cooling. Jon has more than a decade ...

Most heat pumps fall into the broad categories of ducted or ductless, but there are also a number of subcategories you should be aware of when choosing a heat pump for your home. Sam Becker ...
