Air-Handling Units for Data Centers

摘要

Four options for the reliable and cost-effective management of heat in mission-critical facilities. Typical standard rooftop air-handling units (AHUs) simply are not designed to provide the temperature control and redundancy demanded by mission-critical data-center environments. For instance, over a 10-year period, a typical standard rooftop AHU may run for about 30,000 hours, compared with a data-center cooling system, which may run for 80,000 hours or more. Also, while typical service response time for traditional comfort cooling systems is 12 to 24 hours, the criticality of data-center operations demands a response time of no more than two to four hours.
