摘要
建立了间接连接供热系统供回水温度、相对质量流量随室外温度变化的数学模型。结合实例,分析了换热器余量对一、二级管网热力工况的影响。
The mathematical model for variation of supply and return water temperatures and relative mass flow of indirect connection heat-supply system with outdoor temperature is established. The influence of margin of heat exchanger on thermal regime of primary and secondary circuits is analyzed with example.
