2. Pada perhitungan prosentasi beban pada A/C sentral (Package water Cooled) Harga EER untuk split sebesar 7,33 (Btu/h)/W

3. Langkah-langkah penghematan yang bisa dilakukan sehubungan dengan rendahnya beban pendingnan pada package water coioled adalah sbb:

Dengan pengaturan pembebanan pada kompresor tiap unit Package water cooled akan menaikan effisiensi dari 50 % ke 85 % atau akan

menghemat konsumsi listrik sentral 41 % atau 20 % (41%x 52%) dari total A/C atau 11 % (20 %x 57% ) dari konsumsi listrik Total.(salah,75% ke 85%, 11,76% untuk 41 % dan seterusnya)

4. Selain itu langkah Houskeeping yang perlu dilakukan adalah :

Kenaikan shading yang disebabkan oleh pembukaan shading saat siang diperkirakan 0,2 hingga harga Shading Glass menjadi 0,85 dan menyebabkan

harga building load naik 19 % dari exposure atau total (Inc Interior ) 17,4%. Sehingga menaikan konsumsi

menjadi 9,9 % (17,4% x 0,57%) dari total konsumsi listrik

1. Pada Perhitungan beban gedung diasumsikan beban out fres air 23 % (OA Load) dan Shading Glass 0,65 , temperatur disetting pada 26 oC

dan dari A/C sentral (package Water Cooled) 7,73 (Btu/h)/W, dari data tersebut diperoleh rata-rata intensitas sebesar 44 w/m2 (85 kCal/hm2) sementara

dari perhitungan diperoleh 49 w/m2 (93 kCal/hm2), hingga kondisi ini cukup hemat
