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 ...

Space Station Freedom will require between 584 and 767 pounds of water per day. To lift this into space would require four or five shuttle flights per year of nothing but water and tankage at a cost ...

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 ...

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 ...

Italian scientists have assessed the technical potential of vapor compression heat pumps assisted by photovoltaic-thermal systems. They analyzed two main configurations of this combination describing ...

Given the environmental concerns of ozone depletion and global warming, an increasing amount of thought, effort, research, and financing is being given to natural refrigerants. Natural refrigerants, ...

A technology firm has developed a new form of water purification that it is hoped will end reliance on bottled water – after testing it on Glasgow canals. Around 24,000 homes in Scotland depend on ...
