Evaluation on Thermal Comfort and Air Quality of Linpan in Western Sichuan
[Objective]The microclimate and air quality of the Linpan in western Sichuan were monitored and evaluated in order to provide reference for the optimization and utilization of the traditional Linpan environment.[Method]Four types of Linpan spaces(forest space,field space,water space,yard space)were selected,and the square space was selected as the control.The dynamic changes of microclimate and air quality of five spaces were monitored from 7:00 to 19:00 in four seasons.Physiological equivalent temperature(PET value)was calculated by Rayman 1.2 to evaluate the thermal comfort,and air quality comprehensive score(F-value)was calculated by entropy weigh method(EWM)to evaluate the air qual-ity.[Result]①The temperature of the square space in spring,summer and autumn were significantly higher than that in the Linpan spaces,while the humidity were significantly lower.②The thermal comfort of the forest space in spring,summer and autumn were the best,and the thermal comfort of the yard space in winter was the best.All five types of spaces can provide"comfortable"thermal sensation in spring and autumn,among which the"comfortable"period provided by the forest space in autumn was the longest(accounting for 86%of the monitoring period).③The concentration of negative oxygen ions in forest space was significantly higher than that in other spaces.The concentration of airborne particulate matter in spring and autumn as well as the concentration of airborne bacteria in four seasons in square space were significantly higher than those in other spaces.④The average F value was the highest in forest space(0.073 5),while the lowest in square space(0.024 1).The F value of water space in spring was the highest(0.105 8),and the F value of square space in winter was the lowest(0.014 6).[Conclusion]Linpan space can ameliorate temperature and humidity to optimize the thermal comfort,and can also re-duce the air pollution and increase the concentration of negative oxygen ions to improve the air quality.
