| 摘 要： | 本文通过模型实验,探讨了在下部送风空调房间内,室内热源所形成的房间传递函数。同时用实验数据按三项系数分别求解得到了不同房间换气次数、不同热源发热量下的房间传递函数系数及其变化规律,并就传递函数系数w_1值同美国ASHRAE手册进行了对比,取得了比较一致的结论。同时还得到了下送风室内热源条件下的房间传递函数与热源特性有关的结论,由此也显示了热源及房间热过程的非线性特征。

| Abstract: | This paper deals with the room transfer functions formed by the heat source insidethe aircondition room with upward displacement air supply system by way of model test.Three room-transfer-function coefficients and their regularity are obtained from testingdata under different air change and different heat source intensity. Comparing the trans-fer function coefficient w_1 with that in ASHRAE handbook, it is almost got the sameconclusion. At the same time, it is obtained that the room transfer functions has to dowith the property of the heat source inside thc room with upward displacement, whichhas shown the non-linear feature of the heat source and the room's thermal process. |
