计算下送风房间负荷的数学模型

Mathematical Model for Calculating Loads in a Conditioned Space with Upward Displacement

通过将下送风空调房间围护结构分成工作区与非工作区两部分,进而建立起了计算其负荷的数学模型,用此模型不但可求解房间负荷,而且还可对各种室内外扰量的影响进行比较和分析。

By dividing the envelope of an air conditioned room with upward displacement into two parts, i. e., one part composes the conditioned zone (the occupied zone) and the other composes the unconeitioned zone (the non-occupied zone), a mathematical model is built up for calculating the loads of the room, through setting up heat balance equation as regard to each of the inside surfaces. The mathematical model not only can be solved to get the needed loads, but also can be used to analyse and compare the affecting factors inside and outside the room, which lays the theoretical foundation of the optimum design of upward displacement system.
