Ventilation Status Analysis And Optimization Strategy Research Of Rural Self-built Houses In Zhengzhou

Indoor ventilation condition is an important guarantee for a comfortable and healthy air environment inside the residential building.With the increasing attention to the living quality,the indoor ventilation of rural houses should also be taken seriously.Affected by the low temperature in winter and the heat in summer,coupled with the constraints of the building's own characteristics and residents' living habits,the rural self-built houses in Zhengzhou have poor indoor thermal comfort and worrying air quality.The worrying air quality has caused a serious negative impact on the residents' living quality.This paper takes the indoor ventilation of rural self-built houses in Zhengzhou as the main research object,and uses the method of combining field investigation and computer simulation analysis to analyze the indoor ventilation status from the aspects of indoor air comfort and air quality.Based on the experimental data,the existing problems in residential ventilation are raised.On this basis,combined with the simulation experiment using CFD software,the indoor ventilation optimization strategy of rural self-built houses in Zhengzhou area is studied.This paper discusses from two aspects.On the one hand,through field investigation and analysis,to understand the current situation of indoor ventilation and air pollution in rural self-built houses in Zhengzhou area.Further analysis of the ventilation situation in conjunction with CFD software to clarify the existing problems and the necessity of ventilation optimization.On the other hand,based on the problems found in the analysis of the status quo,integrate and analyze the design methods and technical methods that can be used to optimize the ventilation of rural self-built houses in Zhengzhou area.Then put forward targeted ventilation reform strategies,and through the computational fluid dynamics simulation Experiments verify its effectiveness.In the study of indoor ventilation optimization strategies for self-built houses in rural areas of Zhengzhou,based on the problems found in the current status analysis section,the optimization directions for optimizing natural ventilation and introducing ventilation equipment were proposed,and a variety of feasible optimization strategies were integrated and analyzed.Furthermore,on the premise of comprehensive consideration of the ventilation effect,equipment cost and construction difficulty,a natural ventilation optimization strategy was proposed to add a ventilation function at the bright window above the inner and outer doors of the building.And a new window fan was introduced to compensate for the natural ventilation affected by the climate Insufficient,two alternative installation solutions for single equipment and multiple equipment are proposed.Finally,the feasibility of the ventilation strategy was verified through simulation analysis,and the best location and plan for the installation of ventilation equipment were determined.
