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 ...

MILWAUKEE — Johnson Controls has announced the introduction of a solar cooling solution to reduce energy costs for large buildings in North America by combining its high-efficiency chillers with ...

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 ...

Absorption chillers use heat, instead of mechanical energy, to provide cooling. The mechanical vapor compressor is replaced by a thermal compressor (see figure) that consists of an absorber, a ...

A thermochromic film embedded with size-optimized microcapsules autonomously switches between passive heating and cooling ...

Scientists in Sweden have integrated a PV device with a molecular solar thermal (MOST) energy storage system, which acts as as a solar cell optical filter and cooling agent. The proposed combination ...
