With the continuous progress of the process of urbanization, urban land is increasingly tense, urban green area continued to decline, the urban ecological environment deteriorating, air pollution, water pollution, light pollution, noise pollution, a serious impact on people's lives. One of the balcony greening as an important form of three-dimensional green city at this stage, it has to adjust the indoor climate, attract dust and harmful gases, reduce urban noise, healthy, improve people's mental outlook characteristics, therefore, to explore the town building balcony green ecological effect of great significance to the promotion of green balcony. In this paper, build green balconies in residential buildings, and near the room to do experimental comparison measurement with two rooms each section, temperature and humidity values ??based on measured data, the comparative analysis of the distribution of room temperature and humidity, and explore the balcony greening cooling the room thermal environment humidifying effect, at the same time, according to the plant transpiration, by theoretical calculation proved warming lower humidity effects and extent of the plant. Its main conclusions are: (1) different points in time, the type of room height, the green balcony room each cross section than the temperature of no balcony greening room is about 0.1-1.0 ° C lower relative humidity than the balcony greening Room 0.1-3.6%; average temperature balcony green room green room no balcony about 0.4 ℃, the average relative humidity is higher by about 1% -2% green room no balcony. (2) In this study, the total amount of plant (green 19.5m2) make 1000m3 column of air temperature decreased 0.06 ° C, relative humidity increased by 0.07%, theoretically proved that the plant's cooling and humidification role. In addition, through the room and plant model assumptions to simplify the numerical simulation of multiple conditions using FLUENT software based on the measured data of various boundary conditions on the thermal environment of the green room with a balcony, and the measured time for 12 noon comparative analysis of the temperature field and the relative humidity field data with the 12-time simulation results to verify the correctness of the model. Near the plant, low temperature, high humidity, the different time indoor temperature and humidity parameters of outdoor to fluctuate and verify the correctness of the numerical model proved FLUENT software in the calculation of green space temperature and humidity impact The feasibility. Finally, on the basis of the verification model, three typical balcony green green form (suspension, mural, hanging and mural combination) numerical simulation analysis of the different forms of green room under each section of temperature and humidity distribution determine the hanging balcony greening optimum balcony green form.
