One optimization method of hourly heat load calculation model for heat storage air-conditioning heating system in different climate zones was proposed. A building model is initially built in six different climate zones. Subsequently, the hourly heat load and steady-state design heat load in different climate zones were analyzed. Simultaneously, the hourly heat load additional coefficient of the air-conditioning system with different heating modes on a typical day was compared. It can be found that steady-state design heat load on a typical day is mostly between the peak load and average load of the air-conditioning heating system. Simultaneously, results indicate that the hourly heat load additional coefficient in each climate zone can be fitted to different exponential functions. When the heat storage capacity of building components was changed, the maximum increase of the hourly heat load additional coefficient of the air-conditioning system with intermittent heating was 5%. Thus, the research of the optimal design of hourly heat load calculation method provides a relative reference for performance improvement of the heat storage air-conditioning heating system.

不同气候区储热空调供暖系统每小时热负荷计算模型的优化方法

提出了一种在不同气候带的储热式空调供暖系统按小时计算的热负荷优化模型的方法。最初在六个不同的气候区中建立了建筑模型。随后,分析了不同气候区的每小时热负荷和稳态设计热负荷。同时,比较了典型日不同采暖方式的空调系统每小时的热负荷附加系数。可以发现,在典型的一天中,稳态设计的热负荷主要在空调供暖系统的峰值负荷和平均负荷之间。同时,结果表明,每个气候带中的每小时热负荷附加系数可以适合不同的指数函数。当建筑构件的储热能力发生变化时,间歇加热的空调系统的每小时热负荷附加系数的最大增加为5%。因此,对小时热负荷计算方法的优化设计的研究为储热式空调供暖系统的性能改进提供了相对参考。
