This image shows a diagram of the cooling system structure inside a CRAH (Computer Room Air Handler).
- Cooling Process Flow:
- COLD WATER enters the system
- Flow is controlled through an OPEN valve (%)
- Water flows at a specified Flux rate (LPM)
- Passes through a heat exchanger (coil)
- Air Circulation:
- Return Hot Air from servers enters the system
- Air is cooled through the heat exchanger
- Air is circulated by fans (FAN SPEED in RPM)
- Air volume is controlled by a Damper (Open)
- Cooled air is supplied to the servers
- Key Control Elements:
- Valve opening percentage (%)
- Fan speed (RPM)
- Damper position (Open)
This system illustrates the basic operating principles of a cooling system used in data centers or server rooms to effectively control server heat generation. The main purpose is to maintain appropriate temperatures by continuously removing heat (Load/Heat) generated by the servers.
The diagram efficiently shows the complete cycle from cold water intake to the cooling of hot server air and its recirculation, demonstrating how CRAH systems maintain optimal operating temperatures in data center environments.
