Rumus Penghitungan Pendinginan

5 komentar
Jika anda tidak mengetahui berapa kapasitas pendinginan untuk ruangan/kamar tidur yang ingin anda pasangi ac, berikut ini saya berikan rumus perhitungan kapasitas pendinginan untuk ruangan/kamar tidur anda.

1 ton refrigerasi = 12.000 Btu / jam
1 ton refrigerasi = 3,51 kw pendingin
(12000 / 3414 = 3,51)
biasanya untuk 1 ton pendinginan, evaporator membutuhkan volume udara sekitar 400 cfm (cubic feet per minute)

Kapasitas pendinginan ac harus disesuaikan dengan ukuran ruangan yang ingin anda pasangi ac, rumusnya adalah : P X L X 500/800 = .....PK
Jika ruangan kamar tidur anda Panjangnya 4 meter dan lebarnya 3 meter, berarti 4 meter X 3 meter x dengan 500/800 = 0.75 PK, berarti ac yg harus anda pasang adalah 3/4 PK.
atau bisa juga anda gunakan rumus P X L X 500 BTU = Kapasitas ac yang anda butuhkan.
bisa juga dengan rumus 37 meter = 12.000 BTU.
untuk rumus diatas tinggi ruangan maksimal 3 meter.
bila tinggi plafon lebih dari 3 meter, tinggal tambahkan saja nilai btu dalam setiap meternya menjadi 750 btu atau 1000 btu atau kalikan dengan kelipatan bila tinggi ruangan 2 kali lipat.

kode kapasitas pendinginan ac berbeda-beda pada tiap merk ac, merk national/panasonic menggunakan kode cs/cw 05 = 1/2 PK, 07 = 3/4 PK, 09 = 1 PK, 12 = 1.5 PK dan 18 = 2 PK.
sedangkan untuk merk Daikin FT 20 = 3/4 PK, FT 25 = 1 PK, FT 35 = 1.5 PK

untuk perhitungan yang lebih spesifik/heat load calculation, anda dapat menggunakan coolpack software.
