PendahuluanDalam merancang sistem air conditioning dalam ruang akomodasi kapal digunakan acuan ISO 7547:2002. Menurut ISO 7547 tersebut untuk menghitung beban pendingin digunakan perhitungan 5.2 yaitu tentang perhitungan transmisi panas. panas dari matahari, personel dan peralatan penerangan merupakan panas tambahan yang bisa menambah pemanas ruangan. Kondisi desain yang digunakan dalam perencanaan ini adalah 22 derajat celcius indoor gangway dan indoor, 28 derajat celcius untuk galley, 40 derajad celcius untuk engine room, 25 derajad celcius untuk pantry dan -20 derajad celcius untuk suhu outdoor.1. Perhitungan Transmisi PanasUntuk menghitung transmisi panas ini digunakan persamaan dari ISO 7547 sebagai berikut :
