東京都心部における地域冷暖房の稼働実態調査研究

摘要

In this research, the operation realities of the heat load characteristic, the equipment composition, the capacity division, the operating number control, and the equipment efficiency etc. of the District Heating and Cooling (DHC) Plants in 54 places in central Tokyo area were understood, and the operating actual conditions of the DHC plant were clarified. It doesn't depend on the heat source method, and the difference is seen by system COP in the difference of the heat load characteristic and the plant operating condition. The operating rate is 50% or less a year, and the operating time by 20% or less exceeds half a year. The heat loss of the year is 22% on the average of heating heat, and 6% on the average of cooling heat. For improving the system COP, the plant makes an effort to dividing the capacity, controlling the operating number etc. of the heat source equipment according to the heat load characteristic in the region. It is hoped that the existing DHC plants improve a further energy conservation performance by load leveling and the expansion of heat demand.%地域冷暖房とは、一定地域の建物群に、一ケ所または数ケ所の熱発生所で作った冷水・蒸気・温水等の熱媒を地域導管を通じて供給し、冷房・暖房・給湯等を行うシステムである。1970年から都市の大気汚染防止対策として日本に導入され、その後エネルギーの有効利用、都市防災、地球環境の保全などの役割を加え、重要な都市基盤施設のーつとして活用されてきた。
