Environmental Benefits of Additional Sunlight Room Heating Technology Applied in Agricultural and Pastoral Areas of Tibet
Tibet is rich in solar energy resources,and the construction of additional sunlight rooms can make full use of solar energy,reduce the use of heating fuel,and effectively reduce the emission of combustion pollutants.The questionnaire survey found that farmers and herdsmen in Tibet generally recognized the effect of the construction of additional sunlight rooms on the improvement of indoor air quality,and believed that the number of households with good indoor air quality increased significantly from 38.5%before the renovation to 68.5%.The sampling and monitoring data showed that the average volume fraction of CO,average mass concentration of PM2.5 and average mass concentration of PM10 indoor before the construction of the additional sunlight rooms were all higher than that after the renovation,and only the average mass concentration of TVOC(Total Volatile Organic Compounds)was lower than that after the renovation.At the same time,the general construction of additional sunlight rooms can effectively improve air quality in local areas,and monitoring data showed that the mass concentration of PM2.5 and PM10 in the pilot project construction area decreased significantly,proving that the construction of additional sunlight houses can effectively improve the air quality in the living areas of farmers and herdsmen,which can provide a new way of thinking for clean heating work in Tibet.
