Abstract

At present, the outdoor thermal environment research methods mainly include two types: the measurement and simulation, the limitation of the field measurement only makes an objective record and reflect on the existing environment of microclimate, it can't make predictions; while the software whether can simulate thermal environment of the scene or environment to make quantitative predictions, to make up for any deficiencies in the study of the measured is a concern. ENVI - met is considered to be the best fluid mechanics simulation software of the outdoor thermal environment, which is mainly in the application of high latitude and cold regions. Based on the research of subtropical country park outside environment thermal comfort, this paper analyzed three seasons of climate data through the experimental research of the east gate entrance area of Guangdong Tianlu Lake Country Park for spring, summer, autumn; and combined with simulation software ENVI-met to build the model, respectively for spring, summer, autumn three season of simulation experiment, then the authors work out the comparative study of the measured and simulated data, and analyzed the change rule to find out the following four conclusions:(1) with the actual measurement of meteorological data as boundary conditions, ENVI-met can simulate microclimate condition of the subtropical hot and humid region country parks outdoor environment; the change trend of simulated data and measured data is identical within the scope of the instrument error.(2) compared with the simulated data and the measured data, it can more reflect the general trend of change, and is not affected by the measured specific emergency on that day.(3) the variations in the data of simulation generally less than the measured data.(4) the hard ground and artificial facilities compared natural tree shade field simulated results is more close to the actual measurement results. Thus this paper could confirm that the simulation software ENVI-met, which began in the high latitudes, is also could be used in the simulative study of subtropical hot and humid area of outdoor thermal environment, and as a aided designing tool; the authors preliminarily found a certain rule for the background parameter setting in the simulation experiment to set up a foundation for further research in the future.
