通过对独立新风加干式风机盘管空调系统在不同室外工况下的试验研究，分析了冷冻水流量调节对空调系统性能及室内温湿度影响。结果表明，随冷冻水流量增加，系统提供的显热制冷量及潜热制冷量增加，而提供的冷量显热比减少；当冷冻水不能满足新风机组制冷要求时，增加水流量可以明显降低室内冷量显热比，在冷冻水流量满足新风机组制冷要求的基础上增加水流量，对新风机组的制冷量及室内显热比的影响不大；增加冷冻水流量对室内温度影响较大，而对室内相对湿度影响较小。
通過對獨立新風加榦式風機盤管空調繫統在不同室外工況下的試驗研究，分析瞭冷凍水流量調節對空調繫統性能及室內溫濕度影響。結果錶明，隨冷凍水流量增加，繫統提供的顯熱製冷量及潛熱製冷量增加，而提供的冷量顯熱比減少；噹冷凍水不能滿足新風機組製冷要求時，增加水流量可以明顯降低室內冷量顯熱比，在冷凍水流量滿足新風機組製冷要求的基礎上增加水流量，對新風機組的製冷量及室內顯熱比的影響不大；增加冷凍水流量對室內溫度影響較大，而對室內相對濕度影響較小。

The effect of chilled water flow on the air conditioning system performance and indoor temperature and humidity is analyzed by researching dedicated outdoor air ventilation and dry cooling air-conditioning system under various outdoor conditions. The results show that the sensible cooling capacity and the latent cooling capacity of the system increase with the increasing of chilled water flow,but the cold sensible heat ratio decreases.The indoor cold sensible heat ratio dramatically decreases when the chilled water can’t satisfy the need of outdoor air processor.The cooling capacity and indoor sensible heat ratio have little differ-ence by increasing water flow when chilled water can satisfy the need of outdoor air processor.The indoor temperature has greater impact by increasing chilled water flow and the indoor relative humidity is otherwise.
