A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to ...

Diffusion absorption refrigeration systems are an advanced class of cooling technologies that operate solely on thermal energy. Unlike conventional refrigeration systems that rely on mechanical ...

Air doesn’t belong in a refrigeration system, and if it gets in, it will cause problems. Air can enter a refrigeration system in many ways, including through tube, gasket, or flange leaks; poor ...

Laser cooling and optical refrigeration are advanced techniques that utilise the interaction of laser light with matter to remove thermal energy from solids. Based on the principles of anti-Stokes ...

Besides superfluous features like touchscreens and internal cameras, basic refrigerator technology hasn't changed much in decades. They still chill your milk by way of chemical refrigerants and ...

Seeking to make cooling more climate friendly and efficient, researchers used an environmentally-benign solvent and a salt – versus hydrofluorocarbons or other liquid refrigerants – to present a new ...

Refrigeration can truly be said to be at the heart of a supermarket’s business — not to be trifled with — which makes what Sobeys is doing fairly remarkable. Canada’s second largest food retailer, ...
