A team of researchers from the U. S. Department of Energy Ames National Laboratory developed a magnetocaloric heat pump that matches current vapor-compression heat pumps for weight, cost, and ...

An international research team has conducted a computational analysis on propane (R290) vapor compression heat pumps integrating a thermoelectric subcooler (TESC) to reduce the power consumption of ...

A large percentage of compressor failures in low-temperature vapor-compression refrigeration system applications originate from overheating. Typical compressor capacity rating data is based on an ...

By removing moisture earlier in the airflow path, a hybrid cooling system can reduce the load on traditional compressors while maintaining indoor comfort ...

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 ...

Vapor compression cycles are predominantly used in air-conditioning, heat pump and refrigeration equipment. A good understanding of transient behaviors of vapor compression systems is critical to ...

Two research teams from the Universitat Jaume I and the Public University of Navarra have successfully tested new refrigerant mixtures, systems, and components that significantly enhance energy ...
