Researchers in Hong Kong have developed a hybrid-energy heat pump that seamlessly combines absorption and compression cycles using crystallization-free ionic liquids, improving efficiency and ...

A researcher from Saudi Arabia's University of Ha'il has conducted an exergy and energy analysis of a PV-driven single-effect absorption cooling system (SEAC) that uses water-lithium bromide (H₂O–LiBr ...

Although absorption chillers were introduced over a century ago, today it is worth examining what’s new and what’s next while dispelling some old misconceptions. Absorption chiller technology has ...

A new passive cooling system relies on evaporation and radiation and requires no electricity. The device can provide up to about 19 degrees Fahrenheit (9.3 degrees Celsius) of cooling from the ambient ...
