摘要
本文用图解法比较空调工程中一次泵定流量系统与采用压差控制和台数调节相结合一次泵变流量系统中冷冻水泵的工作点 ,认为对中小型空调系统 ,采用一次泵变流量系统是切实可行的。
According to graphs,presents constant flow chilled water systems with primary pumps,analyses pumps' characteristics.Point out variable flow chilled water system with primary pumps controlling by press-difference and pumps' is feasible for middle and small air conditioning systems.
