摘要
从干盘管-独立新风空调系统的特点出发,讨论与系统设计有关的2个问题:系统新风量的确定和变新风控制方案下干盘管最不利工况的确定。通过对简单算例进行分析得出:设计系统时,确定系统的新风量应综合考虑室内卫生标准、维持室内正压、人均散湿量、表冷器的处理能力等因素;考虑到新风变化对干盘管的影响,提出通过判断干盘管承担的显热负荷变化规律来确定干盘管的最不利工况的方法。
Based on the characters of dry-coil and dedicated outdoor air system, discusses two issues related to system design, one is the determination of fresh air volume, the other is the determination of the worse condition of dry-coil under variable air volume con trol model. A simple example shows that indoor sanitation, indoor positive pressure, moisture gain from occupant and the handling ability of cooling coil should be synthetically involved in the determination of fresh air volume of the system;taking the influence to drycoil from variation of fresh air into account, raises a method that determines the worse condition of dry-coil by judging the variation of the sensible load of dry-coil.
