Keeping IT equipment cool can be an expensive, energy-heavy endeavor. When it comes to data center cooling systems, one of the main challenges is to optimize power consumption while minimizing the risks of overheating the servers. Standard air conditioning systems can account for up to 40 percent of a data center’s overall power consumption.
The ASHRAE Technical Committee recommends keeping server inlet temperatures between 65–80 °F, with 20–80 percent relative humidity. As a designer, you will need to factor in space cooling, heat rejection, and fluid conditioning while selecting the right data center cooling system(s) for your needs.
Understandably, choosing or replacing a data center cooling system can be time-consuming. At Windy City Representatives, our engineers can help you make the most efficient use of design hours by guiding you through:
Our Data Center Cooling System Options
Most existing data center cooling systems deploy conventional air-cooling technologies. With Windy City Representatives, you can select from a wide range of data center cooling options. We offer energy-efficient, traditional, and newer technologies, including:
Raised Floor Systems
The most common method for data center cooling, raised floor systems are ideal for rooms with a low density of IT equipment.
Layout: A computer room air conditioner (AC) or air handler (AH) delivers cooled air to the servers through the raised platforms’ perforated tiles. After cooling the servers, the air returns to the AC or AH for cooling.
At Windy City Representatives, we offer custom air handling units from AAON, TMI, XNRGY, and Miller-Picking, as well as humidification options from Armstrong Humidifiers.
Cold Aisle/Hot Aisle Containment
Data center server racks are frequently arranged in alternating rows of “cold aisles” and “hot aisles” to keep chilled intake and hot exhaust air from mixing.
Layout: Hot server exhaust is isolated and sent to computer room AC units. To quickly deliver the chilled air to the IT equipment, in-row cooling units are often placed within a row of racks. When implemented in cold air containment, in-row cooling creates a closed-loop arrangement to focus chilled air on the equipment.
Windy City Representatives offers state-of-the-art computer room units from Compu-Aire.
Chilled Water Systems
Many mid-to-large-sized data centers rely on a chilled water system to cool their IT equipment.
Layout: Chilled water passes through coils and into a chiller connected to computer room air handlers. Once the water returns to the chiller, it mixes with condenser water flowing through a cooling tower. This type of system, however, requires data centers to install a chiller plant on their premises.
Windy City Representatives offers cooling towers from Tower Engineering Inc.
Some data centers leverage the cool outside air to lower air temperatures around servers. It is a cost-effective way to rely less on mechanical refrigeration and offers impressive energy savings, especially in cold, dry climates.
Layout: The outdoor air is filtered, humidified, and directed into the data center to regulate the IT equipment’s cool temperature. Another approach is to use water-side economizers to cool room air or use rear-door heat exchangers to directly liquid-cool IT equipment cabinets.
Windy City Representatives carries chillers with free cooling capabilities from AAON, Geoclima, Systecon, and Quantech.
Adiabatic systems, which rely on evaporation’s cooling properties, require less water than their chilled water counterparts. This cooling system selectively removes heat from the environment. Next, the outdoor air passes through a wet filter, which chills it. This cooled air, in turn, significantly reduces the energy the system requires to mechanically cool.
