An air-conditioning unit is shown below. Calculate the heat transfer per kilogram of dry air, assuming changes in kinetic energy are negligible. Air-water vapor P = 100 kPa T = 35 °C φ = 90% Air-water vapor P = 90 kPa T = 10 °C φ = 97% Cooling coils Liquid water at 10 °C

Unformatted text preview: Some water evaporates, the temperature of the air-vapor mixture decreases, and the mixture leaving the duct is saturated. If the process is adiabatic, the exit temperature is known as the adiabatic saturation temperature. At steady-state, make-up water at the adiabatic saturation temperature is added at the evaporation rate. Pressure is constant. Find humidity ratio 1 and relative humidity 1....
