Presentation for aircond

1. INTRODUCTION OBJECTIVE : Designing a complete air conditioning system LOCATION : Bangi , Selangor

2. FLOOR SELECTION

3. METHODOLOGY -Cooling load estimation table -Rectangular duct c hart -Round duct chart -Air Condition Load Estimation table ( Eg . Table 1 – Table 13)

4. Method for ducting design Determine the air required 2. Determine no. of diffuser 3. Design ducting layout. 4. Throw radius  

5. SECTION CFM hr FPM Φ of duct Side of rectangular 5. Determine of ducting sizes using table below

6. Procedure Choose the design and the location. Calculate cooling load using cooling load estimation table. Choose suitable air condition system. Calculate ducting system. Design ducting system.

7. Assumption of design requirement Ceiling = 12ft Maximum operation – 24hours Room condition – 75F, 55%RH, 72gr/lb Outside air – 92F, 60%RH, 136gr/lb Total of people – 25 Sun movement – east to west

8. Result and design Sample for cooling load table

9. DUCTING SYSTEM DETERMINE CFM  

10. DETERMINE NUMBER OF DIFFUSER = = 8  

11. DETERMINE LENGTH AND WIDE SIDE = 8.75 ft = 10 ft  

12. DUCTING LAYOUT

13. EQUAL FRACTION METHOD

14. Total Rsh and cooling load RSH = 134888 Btu/hr Grand Total heat (GTH) = 200768

15. Proposing air conditioning system We choose UATN SERIES UATN210CGY1X.

16. Product specification Horsepower = 21 hp Type – non inverter Refrigerant – r410A Rated cooling – 213btu/hr Rated power comsumption – 16900W CFM = 7600 Dimension - 1,650 x 2,410 x 2,030 (mm) Weight – 930kg

17. Justification Why choose this system? Bigger building Energy Efficient Maintenance wise To conserve space

18. Discussion From the result above we can determine the type of conditioning system for a choosen building. We can indentified the cooling load needed for a floor or a building. Grand total heat is significant factor in determined in air conditioning system.

19. Conclusion As a conclusion, the larger cooling load the more complicated our conditioning system and much more efficient air conditioning system to be used. We are able to design and complete our objective which is to design a system based of calculation of cooling load. Other than that ducting system dimension can be determined and designing the ducting system.
