摘要
健康舒适的学生宿舍环境是保证大学生日常学习生活的必要条件。对上海非供暖宿舍寒潮期室内CO2浓度和热环境参数进行为期29天的实测。结果表明寒潮期上海非供暖学生宿舍室内温度略低于所需供暖室内临界温度,CO2浓度远超过人体长期处在室内所能接受的限制浓度。通过比较不同气密性房间热环境参数和CO2浓度,指出房间气密性对寒潮期间室内CO2浓度影响较大,对室内热环境影响较小。
Healthy and comfortable dormitory environment has a major impact on students'daily life.Indoor thermal environment parameters and CO2 concentration of typical student dormitories under natural ventilation during cold spell was studied through a 29-day continuous measurement.As a result,the indoor temperature is a little bit less than the indoor critical air temperature for heating.However,the indoor CO2 concentration in student dormitory is much beyond the acceptable concentration.Air tightness is pointed out to have a more appreciable impact on the indoor CO2 concentration than on thermal environment parameters by comparing thermal environment parameters and CO2 concentration of two dormitories with different air tightness.
