摘　　要：本文结合集中参数法和有限容积法,对空调机环境实验室升温过程中的动态热负荷曲线和温度曲线进行了数值模拟和软件开发。在此基础上分析了动态热负荷曲线和温度曲线的变化趋势,并与实验结果对比,发现:升温过程的平均热负荷和温度变化总时间的计算误差较小,基本控制在15%以内;温度变化范围大,实验室内部结构复杂,会导致计算误差偏大。Combined with lumped parameter method and finite volume method,numerical simulation and software development of dynamic heat load curve and temperature curve during heating process inside the environmental laboratory were carried out.The variation trend of dynamic heat load curve and temperature curve is analysed.Compared with the experimental results,it was found that the calculation error of average heat load and total temperature change time in the heating process was small,which was basically controlled within 15%.Large temperature range and complex laboratory internal structure would lead to large calculation error.
