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 ...

This is another in a series of columns addressing advanced basics in the understanding of the refrigeration cycle. In this column and the next (on July 4), we look at components. This column will deal ...

Cascade refrigeration systems represent a critical advancement in thermal management, particularly in applications requiring ultra‐low temperatures. These systems employ multiple refrigeration cycles ...

One of the great inventions of our time — in terms of its social impact and influence on the health care and food preservation industries — refrigeration equipment is everywhere, from hotels, ...

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 ...

Laboratory experiments demonstrated excellent results. At room temperature, the method achieved a temperature drop of nearly ...

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, ...

A Chinese research team has broken through a long-standing bottleneck in refrigeration technology by introducing a novel ...
