Last month’s article examined two systems that were experiencing high compressor discharge temperatures. One system had too much refrigerant, while the other had a partially restricted liquid line. In ...

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 ...

Compressed air energy storage (CAES) can be used as long-duration storage for renewable energy-based grids. CAES systems use electrical energy to drive a compressor, and the stored compressed air can ...
