摘要
本文旨在研究采暖房间室温的波动幅度和规律,从而对合理确定分户计量供暖系统的采暖热负荷提供参考意见。为此笔者根据用户调节时室温变化的特点,提出一种应用简化计算数学模型对非稳态传热过程进行模拟的方法。并应用这种模拟方法对不同围护结构条件下典型房间的室内温度变化进行了模拟,得到一系列室温波动曲线。根据这些曲线分析供热附加率、外围护结构条件及房间在建筑中所处位置等因素对室温的影响。
The reseach is aiming to find out fluctuat rages of temperatures in heating rooms and offer referenced advices for ascertaining heating loads. According to indoor temperature wavy characteristics when the user regulates quantity of heat, the author designed a simulant software which applyed a series of relative simple mathematic models to simulate this unsteady-state heat transfer course. By using the sofeware to simulate indoor temperatures fluctuation of typical rooms in different outer building envelopes, a series of indoor temperature curves were obtained. Based on the curves, the effects of heating additive rate, outer building envelopes and positions of rooms in the building on indoor temperatures are analyzed.
