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 ...

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 ...

Air conditioning and refrigeration consume about 20% of global electricity, relying on century-old vapor-compression ...

Refrigeration is the process in which heat is transferred from one place to another under controlled conditions. There are certain different ways of transferring the heat. It is usually done by ...

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 ...
