摘要 现阶段我国中小学教室大部分没有安装新风系统,以自然通风为主,通过间歇性开门窗来满足室内新风需求。而室内开门窗存在通风效率低,送风效果差等问题,极易引起教室室内空气品质不佳,甚至造成呼吸加深,学习效率下降等不良后果。通过对教室内CO_2散发及排除机制研究,计算在具有CO_2浓度控制新风系统下当量新风送风量,该送风量比设计新风量小,具有一定的节能意义。为了研究CO_2浓度控制新风系统节能量,选取典型教室,分析三个工况:具有CO_2控制、按照正常新风设计和无新风设计的三套系统,通过能耗模拟方法分析三种工况下典型教室空调耗电量,结果发现采用CO_2新风控制教室相对于无新风设计可以满足卫生需求且比正常设计新风节能5.1%。 Most of the primary and middle school classrooms in China does not install outside air system,the natural ventilation system were mainly used to satisfy indoor air quality.In winter through intermittent window open to meet the needs of indoor fresh air,the ventilation by window open has low efficiency and bad indoor air quality,and even cause breathing deeply,learning efficiency decline and other adverse consequences.Based on the study of CO2 emission and exclusion mechanism,the equal air volume of fresh air under the CO2 control system was calculated.Compared with the typical classroom with CO2 control,in accordance with the normal design of fresh air and no fresh air design,energy consumption simulation method to analyze the three types of typical classroom air conditioning energy consumption.It was found that the use of CO2 fresh air control classroom relative to no fresh air design to meet the health needs and energy than the normal design of fresh energy 5.1%.
