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.

The basic principle of physics that explains heat pump technology has been in use for centuries. The ancient Chinese used the geothermal power of natural hot springs to heat their homes. However, ...

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 ...

When we think of chillers, we generally think of the systems that are designed to do the heavy lifting when it comes to cooling large facilities — retail stores, office towers, shopping malls, airport ...
