Komponen Utama Chiller<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Secara umum, chiller bekerja dalam sebuah siklus refrigerasi kompresi uap. Komponen utamanya dibagi menjadi dua kategori:<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A. Komponen Mekanikal (Siklus Refrigerasi)<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Kompresor:<\/strong> Jantung dari chiller yang berfungsi memompa dan menaikkan tekanan refrigeran (freon). Jenis yang sering digunakan: <em>Scroll, Screw,<\/em> atau <em>Centrifugal<\/em>.<\/li>\n\n\n\n<li><strong>Kondensor (Condenser):<\/strong> Tempat pembuangan panas dari freon ke media luar.\n<ul class=\"wp-block-list\">\n<li><em>Air-Cooled:<\/em> Menggunakan sirip pendingin dan kipas (fan).<\/li>\n\n\n\n<li><em>Water-Cooled:<\/em> Menggunakan air melalui <em>cooling tower<\/em>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Katup Ekspansi (Expansion Valve \/ TXV):<\/strong> Menurunkan tekanan dan suhu freon sebelum masuk ke evaporator.<\/li>\n\n\n\n<li><strong>Evaporator:<\/strong> Tempat terjadinya pertukaran panas di mana freon dingin menyerap panas dari air, sehingga air menjadi dingin (<em>chilled water<\/em>).<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">B. Komponen Elektrikal &amp; Kontrol<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Kontroler Utama (PLC \/ Microcontroller):<\/strong> Otak dari chiller yang mengatur kapan kompresor, kipas, dan pompa harus menyala atau mati berdasarkan sensor suhu.<\/li>\n\n\n\n<li><strong>Kontaktor &amp; Overload Relay:<\/strong> Sakelar magnetik untuk mengalirkan listrik arus kuat ke kompresor dan motor kipas, dilengkapi pengaman beban lebih.<\/li>\n\n\n\n<li><strong>High\/Low Pressure Switch (HP\/LP):<\/strong> Pengaman tekanan. HP mematikan sistem jika tekanan terlalu tinggi (overheat\/macet), LP mematikan sistem jika tekanan terlalu rendah (kebocoran freon).<\/li>\n\n\n\n<li><strong>Water Flow Switch:<\/strong> Pengaman yang memastikan air benar-benar mengalir di dalam evaporator sebelum kompresor menyala (mencegah evaporator membeku\/pecah).<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2. Panduan Dasar Wiring (Pengabelan) Chiller<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Catatan: Ini adalah diagram prinsip dasar 3-Phase standar. Selalu gunakan kabel bersertifikasi dan pastikan listrik dalam keadaan mati saat instalasi.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A. Sirkuit Daya (Power Circuit)<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Sumber Listrik (R-S-T \/ L1-L2-L3)<\/strong> $\\rightarrow$ Masuk ke <strong>MCCB\/Breaker Utama<\/strong>.<\/li>\n\n\n\n<li>Dari MCCB $\\rightarrow$ Didistribusikan ke <strong>Kontaktor Kompresor<\/strong>, <strong>Kontaktor Kipas (Fan)<\/strong>, dan <strong>Kontaktor Pompa<\/strong>.<\/li>\n\n\n\n<li>Dari masing-masing kontaktor $\\rightarrow$ Lewat <strong>Thermal Overload Relay (TOR)<\/strong> $\\rightarrow$ Menuju terminal motor (Kompresor\/Kipas\/Pompa).<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">B. Sirkuit Kontrol (Control Circuit &#8211; Biasanya 220V AC atau 24V DC)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Sirkuit kontrol dirangkai secara seri untuk sistem proteksi (<em>interlock<\/em>). Kompresor hanya akan menyala jika <strong>semua sensor aman<\/strong>:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">$$\\text{Line (220V)} \\rightarrow \\text{Emergency Stop} \\rightarrow \\text{Overload Relay Contact (NC)} \\rightarrow \\text{Flow Switch} \\rightarrow \\text{LP Switch} \\rightarrow \\text{HP Switch} \\rightarrow \\text{Thermostat\/PLC} \\rightarrow \\text{Coil Contaktor Kompresor} \\rightarrow \\text{Neutral}$$<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Artinya: Jika salah satu switch di atas terbuka (putus karena eror), aliran listrik ke koil kontaktor kompresor akan terputus, dan kompresor langsung mati demi keamanan.<\/em><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3.
