Question
These substances are modeled by the Carnahan-Starling-Desantis and Martin-Hou equations of state. It’s not oil or natural gas, but these substances can form a flash gas when they boil. These substances have “glide” when they have multiple components with different volatilities. The ASHRAE “R” numbering system for these substances begins with 400 when the substance is zeotropic, such as R-410A. The DX system uses these substances, where they change boiling point as they undergo a cycle of (*) compression, condensation, expansion, and evaporation. Thomas Midgley Jr. and Charles Kettering developed another example of these substances, which were phased out by the Montreal protocol due to their effect on the ozone layer. For 10 points, Freon and other CFCs were used as what substances, the working fluids of namesake cooling machines? ■END■
