Abstract


Sustainable development of the world mainstream of development background , combined with the architectural design of the climate is to achieve energy saving, effective way to create a healthy living environment . Shenzhen favorable climatic conditions and human thermal comfort , natural ventilation of residential buildings , as well as energy-saving effect of the natural ventilation of the building Shenzhen utilization of natural resources , combined with climate Building Energy Research direction . In this paper, the survey of 485 residents in Shenzhen indoor thermal comfort with the measured data , indicating that the comfort zone of Shenzhen residents than ASHARE standard comfort zone wider ; affecting indoor thermal comfort air temperature , relative humidity , wind speed research , indicating that the interaction between the three relations with the preparation of a Visual Basic program easy to use PMV visual interface supporting calculations ; energy simulation and CFD method , the upper limit of meteorological parameters Shenzhen indoor thermal comfort conditions removed to meet the thermal comfort of indoor load by the natural ventilation of the building energy-saving effect . Mainly to obtain the following results : First, through literature review and analysis of the measured data , obtained in the case of the PMV calculation method unchanged , Shenzhen natural ventilation environment should increase the thermal comfort range ; , initially identified this thermal comfort range . Secondly , CFD simulation technology to establish a model of rational analysis units indoor ventilation ; simulated three typical residential interior in Shenzhen , meet indoor PMV less than the 1 window open area and an outdoor range of environmental parameters . Finally, three typical building energy simulation software - dest energy simulation to meet the thermal comfort of indoor temperature and humidity conditions, hourly load is removed , the natural ventilation conditions , different design typical building the contribution rate of natural ventilation energy-saving contribution rate and the natural ventilation of the building itself . Shenzhen residential building natural ventilation energy-saving rate , the quantitative analysis has laid a certain foundation .
