Rising energy costs and environmental concerns are boosting interest in air conditioning and refrigeration conferences July 14-17 at Purdue University, drawing hundreds of researchers from around 30 ...

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 ...

When we think of chillers, we generally think of the systems that are designed to do the heavy lifting when it comes to cooling large facilities — retail stores, office towers, shopping malls, airport ...

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 ...
