空调采用不同换新风装置对室内CO2浓度的影响研究

Study of the Concentration of Carbon Dioxide Indoor Air-conditioning Room in Dedicated Outdoor Air Equipment

以目前国内最主要的三种分体式空调独立换新风装置为研究对象,对使用不同换新风装置下的室内CO2浓度进行测试,比较并分析了换新风状态下空调房间室内CO2浓度变化的影响因素,指出进入室内新风的CO2浓度最低是正压型空调独立换新风装置可以更有效的降低室内CO2浓度的原因所在,分体空调独立换新风装置应该设置不同的换新风量等级以保证室内不同人数下的空气品质。

Taking three main domestic current renewal air conditioning unit as an independent study on the use of wind equipment renewal under different CO2 concentration in the indoor test,the paper compared and analyzed the renewal air conditioned room under the impact of indoor CO2 concentration factor that enter the indoor fresh air CO2. Concentration in the lowest positive pressure air conditioning independent renewal wind devices can be more effectively reduce the indoor CO2 concentration of the reason and air conditioning renewal wind device ventilation should be set to different levels to ensure the interior of different size under the air quality.
