Air-conditioning Design Assignment [60 marks] Table below listed the condition of atmospheric air before and to be achieved after going through an air-conditioning process or processes. Before air-conditioning To be achieved after air- conditioning Case 1 Dry bulb temperature, Tdb = 30°C Relative humidity, = 45% Case 2 Dry bulb temperature, Tab 18°C Relative humidity, -40% Dry bulb temperature of 22°C ≤ Tab≤27°C and relative humidity of 40 ≤ ≤ 60% Case 3 Dry bulb temperature, Tab - 35°C Relative humidity, -80% You are required to design an air conditioning process or processes for all the 3 cases above separately when the pressure of atmospheric air is at 1 bar and the volumetric flow rate of the atmospheric air is 10 m³/min. Present the design of process for each case separately which shall include: a) Sketch a schematic diagram of the equipment used for the designed process/processes. [3 marks each case] b) Present neatly the mass balance equation for dry air, mass balance equation for water vapor and energy balance equation for the designed process/processes. [3 marks each case] c) Determine the amount of water removal/added rate and/or the amount of heat added/removal rate for the designed process/processes. [10 marks each case] d) Sketch the process path for the designed process/processes on a Psychrometric chart. [4 marks each case]
