Study On The Design Of New Ventilation Window In Residential Buildings

Window is one of the most important components of buildings,it affects the construction of ventilation,lighting and heating.Heat loss is also a problem.In addition,with the improvement of people's life quality,the demand for building ventilation is expanding.The overuse of air conditioning equipment results in huge energy consumption.Currently,it is essential to solve the energy crisis,serious environmental pollution and haze.Given all the above,it is necessary to research the design of window system,and to work out a plan which can solve the current environmental crisis,as well as meeting the requirement of the indoor environment.The main content of the first chapter of this paper is to analyze and summarize the current indoor and outdoor air environment.Also this chapter researched the current status and development of ventilator,ventilation window,double glass curtain walls and central fresh air system,and to consider a new natural wind technology in the current environment.This technology can not only provide fresh and healthy air,but also meet the requirements of energy saving and environmental protection.The main contents of the second chapter are as follows.It described the working principle,classification of the ventilator and the central fresh air system.Ventilators have the advantage of easily-use,but they need to be integrated because of their individual existence.The central fresh air system can provide a good wind environment for the room,but it is more suitable to new buildings with complex construction process.The working principle,classification of the ventilation window technology and the double glass curtain walls are also analyzed andsummarized.It concludes that it is not obvious that the ventilation effect of these two technologies is affected by the season.Because of weather factors,it can not meet the needs of the users at any time to achieve satisfying ventilation.Finally,a new type of photovoltaic power ventilation window is proposed,and solutions for the current social problems are put forward,The solution is the relationship between building ventilation and energy conservation-photovoltaic systems;building ventilation and haze-composite function HEPA filtration system.In the meanwhile,it considers how to integrate the new ventilation window design.In the third chapter,the working principle and basic structure of the new photovoltaic power ventilation window are described in detail.Then the application status of the components of the new photovoltaic power ventilation window is researched.It also studies The transformation of the solar cell module rate,the use of the battery performance,DC cross-flow fan ventilation,and composite function HEPA filter.After that,according to the residential building room parameters,living area and the use of residential buildings,and the civil heating and ventilation and air conditioning design specifications in the construction of the number of indoor ventilation requirements,a typical case of the new photovoltaic power ventilation windows of the various components is designed and calculated.The research includes the size and selection of the new window,and the user equipment selection table is also proposed.In the fourth chapter,the lighting performance of the new photovoltaic power ventilation window is calculated,which proves that it can meet the requirements of residential building lighting in the architectural lighting design standard.Then the thermal performance of the new photovoltaic power ventilation window is simulated and analyzed by CFD.The thermal performance of the double-layer ventilation window was simulated by the method of comparative test.The ventilation performance of the new photovoltaic power ventilation window was analyzed by PHOENICS.The effect of ventilation and air conditioning technology was simulated by comparing the tested method.The results of the comparative test show that in the summer the new photovoltaic power ventilation window has better performance than the air conditioning technology and the ordinary window ventilation.But thenew photovoltaic power ventilation window still has a lot of room for improvement.The final chapter of this paper is based on the results of the simulation and experiment,which draw conclusions.Suggestions are put forward on how to improve the new ventilation window.
