– James A. Stark, Design and Build Manager for Electronic Environments Corporation (www.eecnet.com), says:
Cooling a space that is larger than required can cause the cooling systems to be less effective and less efficient. While there are definitely some data centers that are deficient in cooling capacity, the majority of the data centers that we encounter are over-cooled. They have more cooling capacity than is required for the load, but cannot cool the loads adequately due to poor air delivery. Improving the air delivery will solve many of the isolated heat load problems and in many cases, will improve system efficiencies.
