BASIC SIZING ( air conditioning ) a . calculate the area to be cooled. b. Using tables determine the coding capacity in BTU / h . c. 1 BTU / hr = 0.00039 ( Hp )

A . PRINCIPAL AND ADMIN OFFICE ( 10 person maximum )

( 7x 9 ) = 63 m2 52-63 m2

In the table ; 52-63 m2 is equivalent to 12500 BTU/ h Condition ; open in day time + 10 % Room ; more than two ( 2 person ) , # person ( 600 BTU/ h )

computation for space area of 52-63 m2

Basic BTU = 12500 + 0.10 ( 12500 ) + 10 ( 600 BTU/ h ) Ans. 19, 750 BTU / h 7. 70 hp

In the table ; 52-63 m2 is equivalent to 12500 BTU/ h Condition ; Too sunny place + 10 % Room ; more than two ( 2 person ) , # person ( 600 BTU/ h )

Computation for space area of 52-63 m2

Basic BTU = 12500 + 0.10 ( 12500) + 20 ( 600 BTU/ h ) Ans. 25,750 BTU / h 10.04 hp

D. faculty 3 @ FOURTH FLOOR ( 15 person maximum )

(7 x 9 ) = 63 m2 52-63 m2

In the table ; 52-63 m2 is equivalent to 12500 BTU/ h Condition ; Too sunny place + 10 % Room ; more than two ( 2 person ) , # person ( 600 BTU/ h )

Computation for space area of 52-63 m2

Basic BTU = 12500 + 0.10 ( 12500) + 15 ( 600 BTU/ h ) Ans. 22, 750 BTU / h 8.87 hp

Computation( SPRINKLER & CISTERN )

Automated Sprinkler

Area per floor= 775. 03 sq. m. The building has an non-combustible construction

; C=0.8 ;

fire demand per floorTotal Fire Demand= 1314.91 gal/min. x 4 =5259.63 gallon Horizontal pipes = 25 mm in diameter Vertical pipes= 102mm in diameter because the building is less than Size of Cistern Tank1314.91 gallon per minute x 30 minutes= 39,447.3 gallons

Fire Escape SystemThe number of occupants per floor:1st floor- 1502nd floor- 2003rd floor-1804th floor- 120

Use: Ordinary use -7.6mm/person

Number of Occupants on 2nd floor ,since it has the most number of occupants.

7.6mm/person x 200 persons = 1520mm or 1.52 m width of the stairwell BRITISH THERMINAL UNIT ( BTU )
