Question: you are required to design an air conditioning process or...

Question details

Before air-conditioning To be achieved after air- conditioning Case Dry bulb Temperature, Tdb 30°C 1 Case Dry bulb Temperature, Tdb 29°C Relative humidity,0-20% Relative humidity,0-70% Relative humidity,0-60% Dry bulb Temperature, 22 °C s Tdb 27 o0C Relative humidity, 40 s Ds 60% Case Dry bulb Temperature, Tdb 17°C Table below listed the condition of atmospheric air before and to be achieved after going through an air-conditioning process or processes You are required to design an air conditioning process or processes for all the 3 cases above when the pressure of atmospheric air is 1.0 atmospheric and the volumetric flow rate of the atmospheric air is 10m3/ min a) Sketch a schematic of equipment/s for process/processes of your design for case 1, case 2 and case 3 (8 marks) b) Analyze and determine the amount of water removal/added rate, and/or the amount of heat added/removal rate for the process of your design for case 1. (3 marks) c) Analyze and determine the amount of water removal/added rate, and/or the amount of heat added/removal rate for the process of your design for case 2. (5 marks) d) Analyze and determine the amount of water removal/added rate, and/or the amount of heat added/removal rate for the process of your design for case 3. (3 marks) e) Sketch the process path for the air conditioning process/ processes you have designed for case 1, case 2 and case 3 on a Psychrometric chart provided Please detach the chart and submit it together with the answer booklet (6 marks)

You are required to design an air conditioning process or processes for all the 3 cases above when the pressure of atmospheric air is 1.0 atmospheric and the volumetric flow rate of the atmospheric air is 10m3/ min.


a) Sketch a schematic of equipment/s for process/processes of your design for case 1, case 2 and case 3. (8 marks)


b) Analyze and determine the amount of water removal/added rate, and/or the amount of heat added/removal rate for the process of your design for case 1. (3 marks)


c) Analyze and determine the amount of water removal/added rate, and/or the amount of heat added/removal rate for the process of your design for case 2. (5 marks)


d) Analyze and determine the amount of water removal/added rate, and/or the amount of heat added/removal rate for the process of your design for case 3. (3 marks)


e) Sketch the process path for the air conditioning process/ processes you have designed for case 1, case 2 and case 3 on a Psychrometric chart provided. (6 marks)

((((the most important part is to determine the amount of water removal/added rate, and/or the amount of heat added/removal rate for the process for each case ))))
