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 ...

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 ...

The modern air conditioning system cools an indoor space by using the refrigeration cycle. This refrigeration cycle works by controlling the level of energy in the system’s refrigerant: Some parts of ...

Solid-state cooling pushes ahead further with the use of higher-performance materials compatible with standard production processes.
