The proposed system uses waste heat by thermally coupling a water lithium bromide absorption heat transformer with a water vapor compression heat pump. It reportedly achieved a temperature elevation ...

A team of researchers from the U. S. Department of Energy Ames National Laboratory developed a magnetocaloric heat pump that matches current vapor-compression heat pumps for weight, cost, and ...

An international research team has conducted a computational analysis on propane (R290) vapor compression heat pumps integrating a thermoelectric subcooler (TESC) to reduce the power consumption of ...

Vapor compression cycles are predominantly used in air-conditioning, heat pump and refrigeration equipment. A good understanding of transient behaviors of vapor compression systems is critical to ...

Will people’s environmental intentions wither in a heatwave? With much of the US, eastern Europe and Asia sweltering, it may be tempting to crank up the air conditioning to make homes and offices more ...

Two research teams from the Universitat Jaume I and the Public University of Navarra have successfully tested new refrigerant mixtures, systems, and components that significantly enhance energy ...
