Research On Optimization Of Existing Residential Indoor Environment Regulation Method In Summer

Under the background of declining outdoor air quality and increasingly complex indoor pollutant components,the indoor environment of existing homes faces many problems.In this paper,the optimization of the existing residential indoor environment regulation program is regarded as the research goal.Through the combination of theoretical research and experimental research,the influencing factors of the program optimization are summarized,and the concept of intelligent house independent control is proposed.Finally,the program selection program is optimized to improve the efficiency of decision making.First of all,it fills the grading limits of relative humidity and wind speed comfort index,determines the superiority limits of the comfort index and carries out unified directions.Based on the fuzzy comprehensive evaluation method,it has established a comprehensive evaluation model for indoor environment and adopted windowing.Behavioral Verification The theoretical model is correct and quantitative assessments of regulatory schemes can be achieved.Secondly,taking the living room of a typical sample room resident as the experimental research object,according to different indoor and outdoor experimental working conditions,the adjustment scheme of windowing mode,air-conditioning temperature setting,fresh air system,and operating gear of purification equipment are respectively designed.Analysis of experimental data shows that,compared with the background temperature of air-conditioned rooms,the 90-degree windows increase the indoor temperature by about 4℃,and the15-degree-lower-suspension open windows increase the indoor temperature by about 2.7℃.Only the fresh air“middle”stalls operate indoors.The temperature increase is about 1.8℃;when equipped with auxiliary operation of the air-conditioning equipment,the above three adjustment modes respectively increase the indoor temperature by approximately 2.8℃,1.7℃,and 0.2℃.When the outdoor air quality is"excellent",compared with the window-only behavior,the timing of the opening of windows,air conditioning,and purification combined to stabilize the PM2.5 concentration is about 5 to 7 minutes ahead of schedule.The combined operation of fresh air,air conditioning,and purification makes The PM2.5 concentration reaches the concentration level in the fresh air operation only 5 to 10 minutes in advance.Thirdly,according to the comprehensive evaluation index M,the effect of the adjustment program is quantitatively evaluated.When the outdoor air quality is"excellent",continuous operation of fresh air for 15 minutes or window ventilation for 10 minutes is the optimal solution.When the outdoor conditions are the other three types of conditions,fresh air,purification,air conditioning for 20 minutes or window,purification,air conditioning 10Minutes is the optimal solution;for indoor conditions where CO₂ and PM2.5 reach the limit,when the outdoor air quality is“excellent”,20 minutes of fresh air operation is the optimal solution;when the outdoor air quality is the other three types of operating conditions,the The window and its combination with the air conditioning purification for 10 minutes or fresh air,air conditioning,and purification equipment jointly controlled and operated for 25 minutes are the optimal solutions;for indoor CO₂ and PM2.5 exceeding the limit conditions,the new air,air conditioning,and purification combined operation for only 30 minutes will reach“Class III requirements.The“effective fresh air”and“circulation mode”are the main influencing factors for the optimization of the plan,and the independent control concepts of ventilation,air conditioning,and purification are proposed.That is,indoor air pollution is solved by window ventilation,and indoor thermal comfort is poorly resolved by the air-conditioning equipment.The problem of indoor chemical pollution is solved by the purification system and the unbundling operation mode proposes new ideas for the design of the independent control of the existing residential parameters.Finally,in order to realize the decision of the intelligent residential program,a program optimization software program is compiled based on the effect of the adjustment program.By inputting the indoor and outdoor parameters and the presence or absence of the control equipment,the comprehensive evaluation index M is output.The system looks for the"best advantage"to automatically select a combination of adjustment mode and adjustment time to improve the efficiency of the program.
