Question:medium

When an air cooler is used in a closed room, air is pulled through the cooler pads. Which thermodynamic process does the air approximately undergo?

Show Hint

In psychrometrics (the study of air-water vapor mixtures), the process of evaporative cooling is represented by a straight line along a constant wet-bulb temperature line on a psychrometric chart.
Lines of constant wet-bulb temperature are also very nearly lines of constant enthalpy. Thus, adiabatic saturation is considered an isoenthalpic process.
