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 ...

The vapor-compression cycle has four stages (compression, condensation, expansion, and evaporation) and one ultimate goal: converting refrigerant into a state that makes it useful as a heat transfer ...

Researchers developed a device to decrease energy consumption of the vapor-compression heat pump cycle, which is commonly used in homes, businesses and vehicles for cooling and heating. The team ...

Automobiles, appliances, power plants, factories and electrical utilities all waste one thing: heat. More specifically, they produce heat as a by-product of their normal operations, but that heat is ...

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 ...

A recent study has unveiled a significant advancement in refrigeration technology. This work introduces an optimized Compression-Absorption Cascade Refrigeration Cycle (CACRC) that remarkably reduces ...
