摘　　要：对串、并联干式风机盘管加独立新风空调系统进行试验研究,通过改变室外工况及室内负荷显热比探究串联和并联系统运行特性以及对室内温湿度的影响。结果表明:对串联系统而言,显热比SHR=0.85时,该空调系统对室内温度及相对湿度均控制在舒适性范围,且维持稳定;SHR=0.75时,新风机组的除湿能力无法满足室内除湿要求。对并联系统而言,室内显热比的改变对室内温湿度的影响较大;负荷率对室内温湿度的影响不大,分别相差约0.2~0.4℃、1%~2%;且显热比对室内温湿度的影响随着负荷率的增加而增大。To research on performance of series or parallel dry-coil and dedicated outdoor ventilation air-conditioning system,by changing the working condition of outdoor and indoor sensible heat load ratio to explore the performance of series or parallel system and the indoor temperature and humidity. The experimental results ： about series system, indicated that when indoor SHR was 0.85, air-conditioning system could maintain the indoor temperature and relative humidity in the range of comfort, and stability; as the SHR was 0.75, fresh air unit’ s couldn’ t satisfy the requirement of indoor air dehumidification. Study results about parallel system show that the efects of indoor SHR on indoor air was big; theefects of indoor load ratio on indoor air was little, is about 0.2~0.4 ℃、 1%~2%; the SHR impact on the indoor temperature and relative humidity enhanced when indoor load increased.
