In order to build a prediction model of the indoor thermal comfort for a given human group,the original predicted mean vote (PMV) equation is reconstructed and simplified,the modified PMV equation is named PMVR (PMV for region),where five variables are needed to be fitted with the dataset of actual thermal sense of a definite human group. As the fitting algorithm,the particle swarm optimization algorithm is used to optimize the solution,and a fixed PMVR can be finally determined. Experiment results indicate... 相似文献

In order to implement the optimal design of the indoor thermal comfort based on the numerical modeling method, the numerical calculation platform is combined seamlessly with the data-processing platform, and an interactive numerical calculation platform which includes the functions of numerical simulation and optimization is established. The artificial neural network (ANN) and the greedy strategy are introduced into the hill-climbing pattern heuristic search process, and the optimizing search direction can be predicted by using small samples; when searching along the direction using the greedy strategy, the optimal values can be quickly approached. Therefore, excessive external calling of the numerical modeling process can be avoided,and the optimization time is decreased obviously. The experimental results indicate that the satisfied output parameters of air conditioning can be quickly given out based on the interactive numerical calculation platform and the improved search method, and the optimization for indoor thermal comfort can be completed. 相似文献

镉试剂在0.32M氢氧化钠溶液中有清晰的还原波,峰电位在—O.60伏和—O.70伏,第一波可用来定量分析镉试剂。镉试剂的浓度在1.6×10_(-7)至1.3×10_(-6)M间,峰电流和浓度成直线关系。本文研究了镉试剂的极谱行为和极谱波性质。结果表明,镉试剂的极谱波是一吸附波,电极反应系镉试剂分子中-N=N-键的还原所致。 相似文献
