进行集中供热系统的技术经济分析,热负荷延续图是一个重要的工具。对于集中供热系统,热负荷不仅只有采暖负荷,往往还会有冬季通风热负荷和生活用的热水供应热负荷。集中供热系统的热负荷延续图由各种热负荷延续曲线迭加而得。 The technical and economic analysis of the central heating system and the heat load continuation map are an important tool. For the central heating system, the heat load is not only the heating load, but also the winter ventilation heat load and the domestic hot water supply heat load. The thermal load continuation pattern of the central heating system is derived from the superposition of various heat load continuation curves.
