Many entering technicians feel like they can never absorb all the details that are involved in the HVACR industry. It is much like looking over a large Thanksgiving meal and wondering how you can ...

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 ...

In three previous articles, we have presented an overview of CO2 (R-744) as a refrigerant, its applications in industrial refrigeration, and a case study of a CO2 cascade system in a European ...

Researchers have developed a new kind of heating and cooling method that they have named the ionocaloric refrigeration cycle. They hope the technique will someday help phase out refrigerants that ...

Scientists at Lawrence Berkeley National Laboratory have developed a novel potential means of alternative refrigeration: ionocaloric cooling. The method involves electrically charged atoms or ...
