Design and Analysis of Office Ventilation System Integrated with Liquid Based Air Filtration System A-Case of Batu Caustic Soda and Cement Factory

Abstract

Recently The Problem Of Air Pollution Is Emerging Due To Increasing Demand Of Fossil Fuel, Vehicle And Factory. Especially One Of The Biggest Problems Is Increase Of A Fine Dust, And Smokes From Different Factory. Since Fine Dust And Other Polluting Particle Was Very Fine Particles Of 10??M Or Less And It Is Difficult To Remove. Adiabatic Cooling Plays An Essential Role In Cleaning Polluted Air And Ensuring Human Thermal Comfort. Due To Its Dependence On A Natural Process Of Air Cooled By Water It Has Many Advantages Over Other Cooling Processes, Those Includes Creating Non-Pollution And Of The Fact That It Uses Fresh Air And Replaces The Air Time To Time, Quite Frequently. This Study Presents Design And Analysis Of Central Liquid Based Air Filtration System Integrated With Ventilation System For Batu Caustic Soda And Cement Factory Office Building. The Basic Principles Including Numerical Dispersion Modeling Of Air Pollution, Numerical Analysis Of Ventilation System And Experimental Evaluation Of Liquid (Water) Based Air Filtration System Saturation Effectiveness(Efficiency), Achievable Temperature Drop, Achievable Temperature, Evaporative Rate, Sensible Heat Transfer Rate And Air Quality Evaluation Of The Systems Are Evaluated. This Paper Also Presents The Results Of False Pollution Creation And Performance Evaluation For The Air Filtration System. Comparative Studies On The Performance Of Liquid Based Air Filtration System For Atmospheric Air Pollution Test With (4-8) Mm Thick Cooling Pad And False Air Pollution Test With 6mm And 8mm Thick Cooling Pad Are Conducted By Using Water As A Cooling Agent During Experimental Test. The Result Showed That The Outlet Temperature, Maximum Saturation Effectiveness, Maximum Outlet Relative Humidity, Maximum Achievable Temperature Drop, Maximum Achievable Temperature, Maximum Evaporative Rate, Maximum Sensible Heat Transfer Rate, Co2, Hcho And Tvoc During Atmospheric Air Pollution Test Are Found To Be 19.7 Oc, 80.02%, 69%, 3.9 Oc, 20.9 Oc, 4.92, 9.3 Kw, 410ppm, 0.007 Mg/M3 And 0.002 Mg/M3, With False Air Pollution Test 20 Oc, 74%, 62%, 6.4 Oc, 21.5 Oc, 1.54, 0.25 Kw, 862ppm, 0.11 Mg/M3 And 0.321 Mg/M3Respectively.
