Dedicated Cooling System
Dedicated Cooling System
The specification, installation, and operation of IT environment cooling systems, are the most essential, yet least understood, of all critical IT environment processes. As the current and emerging IT hardware becomes smaller and uses the same or even more electricity than the equipment it replaced, more heat is being generated in Data Centers and Server Rooms. Precision cooling and heat rejection equipment is used to collect and transport this unwanted heat energy to the outside atmosphere.
TSI provides engineering Consultancy Services, which take away the headache of choosing the most suitable, energy and cost-efficient space solution.
Air cooled systems (2-piece)
This type of system is often referred to as a DX system or split-type system. In an air cooled system half the components of the refrigeration cycle are in the computer room air conditioner (also known as a CRAC unit) and the rest are outdoors.
Air cooled self-contained systems (1-piece)
Self-contained systems locate all the components of the refrigeration cycle in one enclosure that is usually found in the IT environment.
Glycol cooled systems
This type of system locates all refrigeration cycle components in one enclosure (like a self-contained system) but replaces the bulky condensing coil with a much smaller heat exchanger.
Airflow direction
Large floor mounted systems flow air in a downward direction (down-flow) or an upward direction (up-flow) and some can even flow horizontally (horizontal flow). Down-flow systems are used in a raised floor environment or in a non-raised floor environment when system is mounted on a pedestal. Up-flow systems are used in an existing up-flow environment. Horizontal flow systems should be considered for IT consolidations and IT environment renovations using a hot/cold aisle configuration.
Water cooled systems
Water cooled systems are similar to glycol cooled systems in that all refrigeration cycle components are located inside the computer room air conditioner. However, there are two important differences between a glycol cooled system and a water cooled system:
• A water (also called condenser water) loop is used instead of glycol to collect and transport heat away from the IT environment
• Heat is rejected to the outside atmosphere via a cooling tower instead of a fluid cooler.
