High-density quality assurance for cold aisle areas in computer rooms
Q: Is cold aisle containment suitable for high-density computing deployments? A: CAC effectively supports most density requirements up to 15-20kW per rack. Cold aisle containment (CAC) is a proven data center cooling strategy that creates physical barriers around cold air supply zones, preventing contamination from hot exhaust air and eliminating the energy-wasting effects of air mixing. An enormous amount of energy is used every day to maintain an acceptable intake temperature to the IT equipment. This strategy ensures that cool air is delivered. Note that all statements below are based on the following assumptions: ITE delta-T range is 20°F to 25°F (see Table 2), there is sufficient underfloor pressure to produce the desired airflow (CFM) for the type of perforated floor tile or grate (adjusted for the capture index), the temperature of.
