Primary RefrigerantsSecondary RefrigerantsCirculating CoolantsApplicationsEnvironmental ConsiderationsStandardsA primary refrigerant uses a thermodynamic or adiabatic process (evaporation-condensation cycles) to remove heat and cool a region. The ideal fluid has favorable thermodynamic properties, is noncorrosive, nonflammable, nontoxic, stable, environmentally safe, and economical to produce. The trade-offs between these physical properties and environmental considerations play a large role in the selection of refrigerants.See more on globalspecAntifreeze (Glyco)protein Mimetic Behavior of Poly(vinyl Antifreeze in carbon steelChemical plant design (steel) This article is cited by 115 publications.
