Computer Room Air Conditioners (CRACs) are specialty machines that cool rooms, servers, and telecommunications equipment located inside a Houston colocation center. CRAC designs differ from Heating and Ventilation Air Conditioning (HVAC) units. HVAC units deploy in residences and businesses, whereas CRAC units and components are specially designed for operation at data centers.

Air conditioning and refrigeration works by removing heat from the air by varying processes, including heat pumps and convection methods that push the heat outdoors. In the second part of the process, outside cool air, water, ice and chemical refrigerants cool air and then dispel it into the room. CRAC units at a Houston colocation center may also include additional humidifying or dehumidifying components to condition the air.

CRACs deploy in various ways, in conjunction with raised floor systems, rack designs, air/fluid economizers, variable speed fans, condensers, and monitoring instruments. A Houston colocation center’s cooling strategy differs from other data centers due to variations in building architecture, power sources, geography, and climate. Other variables include suite, cage and rack setup.

A Houston colocation center makes every effort to deploy CRAC units in an efficient and cost-effective manner. Houston colocation engineers and technicians work with customers on every component of the cooling system to optimize the environment, ensuring continuous uptime for client IT infrastructure. Some of the concerns include:

·   Accounting for raised floor design.

Raised floors increased the square footage in the room and impact airflow and power usage. Ensure that the raised floors optimize airflow without blockage.

·   Eliminating efficiency cancellations. For instance, a CRAC humidifying a space cancels another that dehumidifies the space.

·   Placing CRAC units in the optimum location in the Houston colocation facility.

·   Turning off or eliminating CRAC units if not needed.

·   Optimizing the CRAC to use thermal stratification.

·   Automating the CRAC so that manually turning on and off becomes unnecessary.

·   Optimizing humidification methods.

·   Unblocking airflow.

·   Conducting maintenance of CRAC units on a regular basis.

·   Consulting regularly with industry associations.

·   Conducting research and discovering additional improvements and strategies for implementation of retro-fittings, new equipment, and expert staff.

·   Developing instructional opportunities so that customers can learn and benefit from efficiency improvements.

·   Investigating new components to improve efficiency, including new types of motors, fans, compressors, monitoring instruments, and better controls.

·   Sealing windows to keep cold air inside and warm air outside.

·   Cleaning the coils and changing the filters.

Customers of a Houston colocation facility should keep in mind that data center staff stands ready to explain and demonstrate CRAC systems. They can also customize a customer’s server suite, cage, or rack with efficient and low cost cooling options. In addition, a Houston colocation center provides virtual hands, a service that aids customers in all manner of IT assistance including CRAC deployment and maintenance.
