Street children are children who used to live their lives on the street. Street children are divided into several categories, namely: children who have problems, children who are on the road but do not live on the street and children who really live on the road. For this reason, we need a place a container the accommodate the problems experienced by street children with the construction of shelter houses by using the application of livable human settlements which means linking the quality of life of street children with their socials, economy and health needs. To find out what facilities are needed for this building is the holding of research methods, using qualitative research method. Then it can be seen the needs of shelter houses and accordance with the needs and activities of these street children
<p>Sistem pendingin <em>O</em><em>rganic </em><em>R</em><em>ankine </em><em>C</em><em>ycle</em> (ORC) merupakan komponen sistem pendingin yang sangat penting. Sistem ini terdiri dari kondensor, <em>dry cooler</em><em>,</em> dan pompa yang berfungsi untuk memaksimalkan efisiensi pada sistem ORC. Jenis kondensor yang digunakan yaitu jenis <em>one shell one pass tube</em> fluida yang juga digunakan pada sistem pendingin, n-pentane (sebagai fluida panas) dan air (sebagai fluida dingin). Penelitian ini bertujuan untuk mendapatkan keseimbangan termal pada kondensor, <em>dry</em><em> </em><em>cooler</em>, dan pompa serta mendapatkan hasil perhitungan analisis termal pada laju perpindahan panas fluida n-pentane dan fluida air pendingin pada kondensor, <em>dry cooler</em><em>,</em> dan pompa ORC 500 kW. Proses pendinginan pada sistem pendingin ORC pada <em>dry cooler</em> telah mencapai temperatur pendingin optimum pada nilai temperatur 25°C sampai 35°C. Hal ini ditunjukkan pada nilai temperatur pendingin <em>dry cooler</em> berkisar pada temperatur 31°C sampai 32°C. Keseimbangan energi pada laju perpindahan panas n-pentane Q<sub>dc</sub> = 2,34 kW sedangkan laju energi yang diterima fluida air dingin yaitu Q<sub>c</sub> = 1,70 kW dan laju energi pada <em>dry cooler</em> Q<sub>eq</sub> = 0,64 kW menurut perhitungan diagram p-h.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
