The goal of data center temperature management and airflow strategy is to reduce the operating costs of the facility, lengthen the life of the equipment, and reduce the occurrence of downtime.  However, human health and comfort are equally important considerations.

 

High heat and humidity as well as cold temperatures and breezy conditions, which can optimize servers and PDUs, can cause employee discomfort and illness and even result in workers compensation claims.

 

According to ASHRAE statistics, extreme temperatures, up to 160 degrees Fahrenheit and as low as 20 degrees, have been recorded in hot and cold aisle scenarios, respectively.  In these instances, stringent stress guidelines for employees must be taken into consideration to avoid complaints and injuries.

 

Thermal Consulting from Critical Facilities Solutions

 

Most facilities will not create extremely high or low temperature conditions. However, all data centers should be continually optimizing their temperature and airflow processes for maximum uptime, for lowest energy consumption, and according to best practices for equipment maintenance and human health/safety.

 

A CFD analysis from Critical Facilities Solutions can assist in identifying:

 

CRAC unit failure scenarios: If one CRAC unit went down for 20 minutes, 45 minutes, etc., how long would it take for the temperature in your room and/or your equipment racks to reach critical levels? What about two or more CRAC units? A CFD analysis can provide you with an indication to the potential risk this would cause to your data center.

 

 

Thermal Load vs. Cooling Capacity for Equipment Installation / De-installation: How many more equipment racks can you install before you reach or exceed the current cooling capacity? If you remove equipment racks can you up the temperature setting on your CRAC units or cycle one out of operation? A CFD analysis can help answer these questions.

 

 

CRAC/CRAH unit performance: Are the CRAC units operating at peak level? Are you losing cooling, humidity, and/or airflow due to poor performance by a CRAC unit, or units?

 

 

Hot Spot / Cold Spot Analysis: Answers to what is causing those hot spots and/or cold spots. A CFD analysis can provide solutions to minimize or eliminate problem areas.
