HVAC Services in MissouriAs computer technology has evolved, so has the density of the power and the associated heat gain related with new computer equipment. Computer server racks that once were nearly empty now are filled and they put a great deal of strain on facilities’ cooling systems.

Tracking electrical power consumption can help technicians anticipate when it is time to introduce cooling to a particular space.  Many times the backup cooling unit becomes the added capacity, and professional technicians add temporary cooling to ensure redundant cooling until the installation of a permanent solution.

This situation is commonly encountered and manifests itself when the base building HVAC system is used to cool space that has been dedicated to the placement of computer equipment. Most generally the space was originally a small data room, but with the growth of technology has become a large server and data storage farm.

As a result mechanical systems struggle to keep up and maintain efficient operations 24/7.  At this point managers might arrange for the installation of a ‘temporary portable air conditioning’ that will reject heat generated by the servers into the buildings return air duct. This will give facilities maintenance an opportunity to design and implement a more permanent cooling solution.

Whenever facilities managers can integrate server expansion with increased cooling capacity, the ideal solution is in-rack or above-rack cooling.

In-rack systems use a hot-aisle/cold-aisle strategy, this is where cool air is introduced to the front side of the servers, and server fans reject heat to the rear, where is it is then cooled by the  in-rack system.

These systems can reduce cooling demands by up to 60 percent by utilizing a greater air temperature differential than a traditional mixed cooling solution.

Cooling systems might involve refrigerant or chilled water.  Refrigerant can be routed overhead, and chilled water systems are best served from below a raised floor. Each option requires extensive careful planning and consideration to achieve efficiently and affordability.
