Data Center Cooling

September   •   2015

Proper management of the data center environment is critical to the success of the business that hosts it. Assessing a micro-climate environment and developing an energy conserving cooling system requires a complete understanding of all aspects of Computer Room Air Conditioning (CRAC) and server rack cooling.

 

Server Room & Micro-climate Factors:

•Heat Load

•Temperature

•Humidity

•Air Flow

•Air Cleanliness

•Filtration

 

By identifying the heat load of your data center, Pacific West Industries can design and install (or repair and upgrade) a variety of Computer Room Air Conditioning systems for your facility. It is also important to consider the current and future power requirements, size and location before purchasing new or upgrading existing systems. The heat load depends on a number of factors that are considered for an accurate measurement.

 

Heat Load Factors:

•Floor Area of room

•Size and position of windows

•Window shades, blinds or tinting

•Room occupants

•Equipment heat generation

•Lighting heat generation

 

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) is an international technical society organization and a leading authority providing recommendations for data center cooling and humidity ranges. ASHRAE TC 9.9 recently released their "2008 ASHRAE Environmental Guidelines for Datacom Equipment" which expanded their recommendations:

 

Temperature: 18°C (64.4°F) to 27°C (80.6°F)

Humidity: 5.5°C DP (41.9°F) to 60% RH & 15°C DP (59°F DP)
