概要:
当社が開発した水和物スラリー(CHS)は高い冷熱密度と優れた熱輸送性能を持っている。CHSを空調システムに適用すると，搬送動力の低減，配管・貯槽のコンパクト化による経済性の向上が期待される。当社京浜製鉄所内の事務所建物にCHSを用いた空調システムを設置し，夏季に運転した結果，搬送系統の動力を約50％低減することが確かめられた。また，大型ビルに適用した場合の省エネルギー性を実験データに基づいて試算した例を示す。
Abstract:
NKK has developed a CHS (Clathrate Hydrate Slurry), which has great cooling capacity and pumpability. The utilization of CHS in air-conditioning systems is expected to reduce pumping power consumption and capital cost due to downsized piping and tanks. The CHS air-conditioning system has been applied to an office building in NKK Keihin Works. The operation during Y2000 summer revealed that the pumping power consumption was reduced to 50% of that for chilled water system. Based on the obtained data, we also conducted a feasibility study on the CHS air-conditioning system applied to a large office building.
