STUDY ON OUTDOOR THERMAL ENVIRONMENT OF APARTMENT BLOCK IN SHENZHEN, CHINA WITH FIELD MEASUREMENT AND COUPLED SIMULATION OF CONVECTION, RADIATION AND CONDUCTION

摘要

Shenzhen City in China is rapidly developing now. Correspondingly, deterioration of the outdoor environment such as the heat island, etc., has become serious problems. This aggravation of thermal environment has spoiled urban sustainability. In this paper, (1) in order to predict outdoors thermal environment in summer in the apartment block, unsteady coupled simulation of convection, radiation and conduction is developed and used. The velocity, temperature, and humidity, MRT in urban area were given from the simulation. In order to estimate pedestrian level thermal comfort in the outdoor thermal environment, spatial distributions of SET~* was calculated by above result. (2) actual situation of the outdoors thermal environment in summer in an apartment block in Shenzhen city is investigated with field measurement. (3) The spatial distributions of wind velocity, air temperature, humidity and MRT in the same area where the field measurement was conducted are analyzed by the above simulation method. The numerical results are compared to the field measurement in order to confirm the accuracy of prediction for this method.
