Those small-diameter coils — with names like MicroGroove, microchannel, and micro-multichannel — have gained a beachhead in residential heating and air conditioning, and are advancing in commercial ...

Researchers in Italy have designed a novel carbon dioxide heat pump that can work with photovoltaic-thermal energy, a finned coil heat exchanger and a U-tube borehole heat exchanger. Their experiment ...

Researchers in Italy have conceived a dual-source heat pump system that uses both a finned-coil evaporator and a solar evaporator made with three photovoltaic-thermal panels. Thanks to the combined ...

Efficient heat transfer is a top priority for industrial equipment performance. If heat transfer is uneven or unpredictable, the results range from increased maintenance demands to reduced machine ...

Unwanted heat is a problem for all hydraulic systems. Even a well-designed system operating at top efficiency converts about 20% of its input power to heat. An inefficient system, or one poorly ...
