    A dehumidifier receives a flow of 025 kgs dry air at 28°C, 80% relative humidity, as shown in the figure. It is cooled down to 20°C as it flows over the evaporator and then is heated up again as it flows over the condenser. The standard refrigeration cycle uses R-22 with an evaporator temperature of5°C and a condensation pressure of 1600 kPa. Determine: (a) the amount of liquid water removed, (10 points) (b) the heat transfer in the cooling process,...

    A stream of air (stream 1) at 60°F, 1 atm, 30% relative humidity is mixed adiabatically with a stream of air (stream 2) at 90°F, 1 atm, 80% relative humidity. A single stream (stream 3) exits the mixing chamber at temperature T3 and 1 atm. Assume steady state and ignore kinetic and potential energy effects.

    a. Calculate the dry air and water vapor mass flow rates (lb/min) if the volume flow rate is 1,000 cfm, the humidity ratio is 0.025 lbv/lba, and the dry air density is 0.072 Iba/ft3. b. Assume the above air enters an evaporator coil at 90°F where it is cooled in a constant humidity ratio process until reaching the 100 % RH curve ( the temperature at that point is the dew point. The air then keeps dropping in temperature, following...
