TABLE OF CONTENT OVERVIEW OF A DATA CENTER HVAC COOLING SYSTEM DESIGN DATA CENTER HVAC EQUIPMENT DATA CENTER AIR DISTRIBUTION COOLING PERFORMANCE AND EFFICIENCY
DEFINISI DATA CENTER Data center atau pusat data merupakan fasilitas yang digunakan untuk menempatkan beberapa server atau sistem Komputer dan sistem penyimpanan data (storage) yang dikondisikan dengan pengaturan daya dan udara, pencegahan bahaya kebakaran, dan biasanya dilengkapi pula dengan sistem pengamanan fisik. Pusat data dibagi menjadi dua bagian utama kategori: pusat data perusahaan (CDC) dan pusat data Internet (IDC)
persyaratan fungsional dari data center: Perencanaan ruang pusat data Pasokan listrik dan konektivitas jaringan Suhu / Kelembaban
DATA CENTER SPACE PLANNING AND DESIGN Moisture and air leakage Contaminants Access Security Room temperature and humidity Airflow Raised flooring Ceiling height Aisle space Expansion room
ELECTRIC SUPPLIES AND NETWORK CONNECTIVITY Estimated Power Requirements Quality of Power Emergency Power Grounding Physical security and fire protection Emergency Power Control

2. Temperature and humidity requirements Temperature Dry bulb temperature: 18 to 27属C Dew Point : 5.5 to 15 尊C Effects of Temperature : Jika suhu naik terlalu tinggi, peralatan akan tidak berfungsi , dan komponen internal mulai membengkak dan menjauh dari satu sama lain (atau dapat terbakar). Relative Humidity or Absolute Humidity Relative humidity (RH) and is specified as 55 賊 5% Effects of Humidity: Jika udara di pusat data terlalu lembab, air dapat mengembun pada komponen internal, menyebabkan electical short Jika udara terlalu kering, pusat data berisiko terkena aliran listrik statis juga bisa menghasilkan short circuit

Water cooled chillers Air cooled chillers
Parameter DX Chiller Space Eliminates space requirement Large plant room required. Capital Cost Lower cost Higher capital cost Energy Cost high higher COP and has lower power consumption Spare Parts Small, economical and easily available expensive, available only from the manufacturer Compressor Failure the single machine only is affected and the compressor is easily and quickly replaceable. Chiller compressor or motor failure results in extended downtime of several weeks and very high cost. Piping Simple, but risky requires insulation
