“The proposed system integrates photovoltaic power generation with direct-cooling and vapor compression refrigeration (VCR),” the research's lead author, Xiaohui Yu, told pv magazine.

(Watch a YouTube video.) The engineers’ May flights will test possible solutions to making the type of cooling process that a typical fridge uses – vapor compression refrigeration – reliable enough ...

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 refrigeration industry has explored ways ... head and shoulders above the 60 percent efficiency of a typical vapor-compression fridge. Like that standard device, a twist fridge would cool ...

There's no word on the current efficiency of the system, only that their eventual goal is to be 20-30% more efficient than vapor-compression refrigeration. If such efficiency gains can actually be ...

A team of researchers from the U. S. Department of Energy Ames National Laboratory developed a magnetocaloric heat pump that ...

Jacob Perkins, who worked with Evans, received a patent for a vapor-compression cycle using liquid ammonia in 1835, according to History of Refrigeration. For that, he is sometimes called the ...
