Menghitung Load DC
Head Load Server : 300000 BTU/h
Ruangan : 15m x 9m = 135m
135 x 75 w = 10.125 kW (34546 BTU/h)Lampu (TL) Kurang lebih : 70 pcs x 36 w = 2520 w x 125% = 315 kW
3.15 kW = 10747 BTU/h
PIC kurang lebih : 10 org x 720 = 7200 BTU/h
Total Head Load adalah:
300000 + 34546 + 10747 + 7200 = 352493 BTU/h ( 103.31 kW )
Jadi kebutuhan PCU adalah :
2 unit dengan kapasitas 180000 BTU/h per unit
