Researchers at the Hebei University of Technology in China have designed a solar photovoltaic direct-drive refrigeration system with low energy consumption for high heat-flux electronic device cooling ...

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 ...

Air conditioning and refrigeration consume about 20% of global electricity, relying on century-old vapor-compression ...

A large percentage of compressor failures in low-temperature vapor-compression refrigeration system applications originate from overheating. Typical compressor capacity rating data is based on an ...

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 ...

The Korea Institute of Energy Research (KIER) has developed, for the first time in the country, a refrigeration technology that uses air as a refrigerant instead of Freon gas, hydrofluorocarbons (HFCs ...

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 ...

The majority of the waste water from small isolated outposts such as Antarctic bases and planned Lunar and Martian bases consists of gray water-- water from clothes- and dish-washing, and crew hygiene ...
