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 ...

Refrigerators are a necessary aspect of modern life, but most of them rely on a cooling mechanism called vapor compression—and the vapors involved tend to be potent greenhouse gases that can ...

Vapor injection heat pump systems represent a significant advancement in heating technology by integrating a secondary injection of refrigerant vapor into the compressor. This process enhances the ...

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 ...

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

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 ...

The Korea Institute of Energy Research (KIER) has developed, for the first time in the country, a refrigeration technology that uses air as a refrigerant instead of Freon gas, hydrofluorocarbons (HFCs ...

Heat pumps are devices that work like a refrigerator in reverse, moving heat from the air or ground outside a building to its inside, through the circulation of a refrigerant. In the case of an air ...

The majority of the waste water from small isolated outposts such as Antarctic bases and planned Lunar and Martian bases consists of gray water-- water from clothes- and dish-washing, and crew hygiene ...
