本文通过对旅馆标准客房建立简单的数学模型,分析了房间的传热机理,描述了计算房间传递函数系数的数学基础,并编制了能计算各种房间传递函数系数——“用户权系数”的电算程序.同时,尝试了一种求解房间传递函数系数的新方法——拉氏递变换法.该法通过求房间传递函数的极点来确定W_i,能对各种波形的得热曲线求解,从而提高了精度.根据计算结果,分析了影响房间传递函数的主要因素.最后,对计算结果进行了实测验证.
This paper establishes a simple mathematical model for the hotel standard rooms, analyzes the heat transfer mechanism of the room, describes the mathematical basis for calculating the transfer function coefficient of the room, and compiles the coefficients that can be used to calculate the transfer function of various rooms—“user weight coefficient”. The computer program. At the same time, a new method to solve the transfer function coefficient of the room is proposed - Lagrange transformation method. This method determines the W_i by finding the pole of the room transfer function, and can solve the heat curve of various waveforms. Therefore, the accuracy is improved. Based on the calculation results, the main factors that affect the transfer function of the room are analyzed. Finally, the calculation results are verified by the actual test.
