Data Center Cooling System Chilled Water & CRAH Units Cooling is one of the critical systems keeping a data center alive. Servers, storage systems, networking equipment and other IT infrastructure continuously consume electrical power and convert most of it into heat . If this heat is not removed effectively, equipment temperatures can rise rapidly, resulting in thermal throttling, alarms, equipment shutdown, reduced component life and potentially loss of critical IT services. A typical chilled-water data center cooling system with CRAH (Computer Room Air Handler) units continuously transfers heat through the following path: IT Equipment Hot Aisle CRAH Unit Chilled Water Chiller Condenser System Cooling Tower / Outdoor Environment The system is therefore not simply producing cold air. Its real purpose is to capture, transport and reject heat continuously and reliably. 1. Heat Generation Inside the Data Hall Servers draw electrical pow...
Detailed schematic diagram of a chilled water system, illustrating how chilled water is produced and circulated to a fan coil unit (FCU) for air conditioning. The system involves several components and stages: + System Flow Overview Chiller Plant: The chilled unit produces cold water, typically around 6-7°C (43-45°F), by removing heat through a refrigeration cycle. Pump Section: The primary CHW pump circulates the chilled water from the chiller into the distribution network. hashtag Activate to view larger image,
