| In order to effectively improve the indoor environment in Hefei,Questionnaire survey was conducted on indoor thermal comfort,the survey results show that people feel uncomfortable under summer indoor thermal environment in Hefei.Then using comfort level gauge measuring the indoor thermal environment related parameters.And by using Phoenics software to simulate the indoor air flow field and temperature field in the process of natural convection,Analysis of Hefei summer indoor temperature and humidity and thermal comfort.By comparing the experimental measurement data and simulation results show that using software analysis room internal thermal comfort is accurate,And then analyzes the main reasons of Hefei poor indoor environment.On the basis of the above analysis put forward relevant ideas to improve the residential indoor thermal environment of Hefei,Two kinds of improved schemes are presented,respectively from the Angle of the passive mode and active mode.Passive way through reasonable natural ventilation to reduce indoor load to improve indoor thermal comfort.Active way is through the use of air conditioning system to improve the indoor thermal environment.At the same time using the desT simulation of building energy consumption analysis verify the feasibility of the ground source heat pump to use.From the Angle of energy saving,to effectively improve the indoor environment to provide the reference. |
