摘　　要：供暖系统间歇运行时应对热负荷进行间歇附加,附加负荷的大小和分布规律对系统(尤其对蓄热系统)的设计非常重要。目前缺乏逐时间歇附加的设计计算依据和方法。结合《蓄冷空调工程技术规程》修编中开展的设计日逐时热负荷专题研究,采用动态模拟软件计算分析了不同间歇运行模式、蓄热体结构、气象参数条件下的设计日逐时热负荷。提出了间歇运行逐时热负荷附加表,可用于对连续运行的设计日逐时热负荷进行逐时间歇附加修正,为工程设计中间歇供暖负荷的确定提供依据。Intermittent heating load should be added intermittently to heating system. The magnitude and distribution of additional load are very important to system design, especially for thermal storage system. However, there is still a lack of additional hourly load design and calculation basis and methods for intermittent heating system. Combined with the study of hourly heating load of design day in the revision of Technical specification for cool storage air-conditioning system, calculates the hourly heating load of design day under different intermittent operating modes, thermal storage composition, meteorological parameter by dynamic simulation software. Puts forward a table of additional hourly heating load in intermittent operation, which can be used to make additional hourly intermittent revision on hourly heating load of design day when continuous operation and also provides references for the determination of intermittent heating load in projects.
