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.

A heat pump functions as a typical air conditioning system in the cooling mode — absorbing heat from indoors and rejecting it outdoors. In heating mode, the coils reverse their functions. The outdoor ...

Researchers in China proposed a solar-driven integrated system that combines reversible heat pump and organic Rankine 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 say that cascaded organic Rankine cycle systems could improve the way in which environmentally-friendly power is generated from waste heat. A team from City, University of London's ...
