The proposed system uses waste heat by thermally coupling a water lithium bromide absorption heat transformer with a water vapor compression heat pump. It reportedly achieved a temperature elevation ...

Researchers at the Chinese Academy of Sciences developed a thermoacoustic Stirling heat pump prototype that offers high thermal performance, a peak coefficient of performance of 1.68, and potential ...

CHICAGO - Hydronic systems can require a number of different parts, and many of these items were displayed at the 2009 International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo).

Moving molten metals may lead to new energy conversion and storage devices. A ceramic-based mechanical pump developed at the Georgia Institute of Technology, with help from engineers at Purdue and ...
