摘  要:随着室外大气环境及室内装修的污染,长时间处于室内的工作人员身体健康受到严重威胁,空气净化显得尤为重要。通过在传统空调系统中增加绿色植物和二氧化钛(TiO_(2))光催化装置,既可满足空调房间的热舒适性要求,同时又能满足新鲜度和消毒杀菌的需求,从而持续创造健康、舒适的室内环境。其中TiO_(2)光催化材料可对来自新回风空气中的甲醛,氮氧化物(NO_(x)),以及其他有机污染物进行降解和杀菌,释放CO_(2)和H_(2)O;绿色植物不仅能在光照作用下进行光合作用,吸收混合空气中的CO_(2)和H_(2)O,释放大量氧气(O_(2)),增加空气中的含氧量和新鲜度,而且还可吸附空气中的大颗粒灰尘及PM2.5,从而进一步净化空气。通过模拟和实验证实了绿植协同光催化净化空调系统方案的可行性,得到NO_(x)浓度最大降解率可以达到30%。With the pollution of outdoor atmosphere and interior decoration,Staff who have been indoors for long periods of time are seriously threatened with health,Air purification is particularly important.By adding green plants and titanium dioxide(TiO_(2))photocatalytic devices to traditional air-conditioning systems,It cannot only meet the requirements of thermal comfort of air-conditioned rooms,but also meet the needs of freshness and sterilization,So that it continuously creates a healthy and comfortable indoor environment.Among them,TiO_(2)photocatalytic materials can degrade and sterilize formaldehyde,nitrogen oxides(NO_(x))and other organic pollutants from the mixed air and release CO_(2)and H_(2)O.Green plants not only carry out photosynthesis under light,absorb CO_(2)and H_(2)O in mixed air,and release a large amount of oxygen(O_(2))to increase the oxygen content and freshness in the air,but also adsorb large particle dust and PM2.5 in the air to further purify the air.In this paper,the feasibility of the purifying air-conditioning system with the green plant and synergetic photocatalyst was verified based on the simulation and experiment,the maximum degradation rate of NO_(x)concentration could reach 30%.
