Refrigerating and Air-Conditioning Technologies in a Small Energy Network Type Food Industrial Park

抄録

The study was undertaken to evaluate refrigerating and air-conditioning technologies in cases of introducing both co-generation systems and energy networks at a food industrial park. Energy data of 12 factories obtained from interviews were classified into those of steam, hot water, heating, cooling, refrigerating, freezing, and electric power. The author developed a smart energy network model based on linear programming to minimize the total system cost. The industrial park was divided into 2,500 square meter meshes to incorporate analyses of steam transport. This study investigated four cases. The ratio of energy saving to demand reached 18 % compare with the reference system. It was introduced only slightly into the refrigerating supply though a heat driven chiller introduced into the air-conditioning supply in the smart energy network system. The inter-factory steam network became more advanced than the inter-factory electric power network. Results of these simulations underscore the useful role of a smart energy network in communities of the future.
