From c|net news, word of a new data center air conditioner that uses ice
The idea behind Ice Energy’s Ice Bear air conditioner is to make ice in a storage tank during off-peak times to take advantage of lower rates. The machine uses the stored ice to make cool air during times of higher energy demand–and higher rates.
Ice Energy and Data Aire said they have tested a way to link the Ice Bear to Data Aire’s cooling systems. The companies said that the combination is more efficient than stand-alone systems and will cut peak electricity usage.
This could certainly make a difference for those with datacenters in areas of the country where humidity and year-round heat make outside air economization impractical.
