Vysokoeffektivnye resheniya dlya sistem okhlazhdeniya s ispol'zovaniem frikullinga i rekuperatsii tepla na baze oborudovaniya Climaveneta

The problems of the efficient cold supply and recovery of heat release of large data handling centers are examined. In the beginning of the paper the examples of different methods of cold supply are cited, the necessity and economic benefit of heat recovery of refrigeration plants are grounded. Further different methods of cold supply are compared in terms of electric power annual costs using a data handling center at 1 megawatt capacity as an example. The efficiency of the large data handling center operation is analyzed with calculation of the PUE coefficient. The schemes and examples of using recovered heat according to current rates and norms on consumption of services in the housing and municipal sector are given. In conclusion a short list of Climaveneta S.p.A. refrigerating plants with free cooling technology and possible heat recuperation that may be used for a twelvemonth cold supply of data handling centers is cited. So, the article proves with convincing arguments the efficiency of using the scheme with heat recuperation offered for a large data handling center. Keywords: efficient cold supply for a data handling center; chiller; recuperator; free cooling; heat supply.
