Heat-exchanger designs for a two-stage launch system that collects and liquifies air while in the cruise are to be tested by the European Space Agency. An ESA study has found it should be possible to ...

Earth-Air Heat Exchanger (EAHE) systems utilise the relatively stable subsurface temperatures to pre-condition ventilation air, offering a sustainable alternative to conventional heating and cooling ...

Researchers at the University of Padova in Italy have proposed to improve the performance of residential air heat pumps with air-geothermal heat exchangers and have found this combination may reduce ...

Now offered in 120VAC and 24VDC models, the Stratus line of air-to-air heat exchangers features compact, deep, and tall frame sizes. The Stratus line of air-to-air heat exchangers now includes 120VAC ...

Researchers at the Central University of Jharkhand in India have developed a thermal energy system for buildings that uses an earth-to-air heat exchanger (EAHE) system powered by a standalone PV ...

When superchargers and turbochargers compress air, that air is heated, resulting in a rise in inlet air temperature. On a turbocharger, the exhaust-driven turbine side additionally transfers added ...
