Problem 19.91 A standard air conditioner involves a refrigerant that is typically now a fluorinated hydrocarbon, such as CH₂F₂. An air-conditioner refrigerant has the property that it readily vaporizes at atmospheric pressure and is easily compressed to its liquid phase under increased pressure. The operation of an air conditioner can be thought of as a closed system made up of the refrigerant going through the two stages shown here (the air circulation is not shown in this diagram). Expansion chamber Liquid ▼ Liquid Part A Compression (high pressure) During expansion, the liquid refrigerant is released into an expansion chamber at low pressure, where it vaporizes. The vapor then undergoes compression at high pressure back to its liquid phase in a compression chamber. What is the sign of q for the expansion? O Positive. O Negative. Submit Expansion (low pressure) Compression chamber Part B Request Answer What is the sign of q for the compression? O Positive O Negative. Vapor Vapor 1 of…
