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 ...

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 ...

The decarbonization of the HVACR industry is on full display in 2023. This is largely because legislators worldwide have set net-zero targets for the carbon dioxide (CO 2) expelled into the atmosphere ...

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 ...
