热负荷是冷热电联供系统设计的重要依据,本文对热负荷的种类进行划分,根据负荷类别的不同提出了调研统计法与指标估算法,并根据项目实践对两种热负荷统计方法做出了示例。对冷热电联供系统项目前期的规划、可研有较强的借鉴参考意义。 Thermal load is an important basis for the design of combined heat and power system. In this paper, the types of heat load are divided. According to different types of load, statistic method and index estimation method are proposed. According to the project practice, An example is given. On the CCHP system pre-project planning, feasibility studies have a strong reference for reference.
