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.

UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The ...

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 ...

South America’s first and only geothermal power plant, the 48-MW Cerro Pabellón project, sits at an elevation of 4,500 meters above sea level in Chile’s harsh and remote Atacama Desert. Building and ...
