Development of a rack-type air-conditioner for improving energy saving in a data center
2009
We developed a rack-type local air-conditioner, focusing on the elimination of hot spots to reduce the energy consumption of data center air-conditioning. In doing so, we also regarded increasing the operating efficiency of the air-conditioner itself as an important problem. We therefore took up the challenge of developing energy saving techniques that optimize computer room air-conditioner as well as adopting a structure and control technology for more efficient local cooling. In this paper, we introduce those energy-saving techniques for a rack-type air-conditioner. Trial calculations of the air-conditioning method used together with this rack-type air-conditioner confirmed that a 43% reduction in the energy used for air-conditioning relative to the ordinary VUF (vertical under floor) method is possible‥
