摘要(Abstract):

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的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 constant flow chilled water systems and variable flow chilled water systems with primary pumps was presented and pumps' characteristics was analysed. Variable flow chilled water system with primary pumps controlling by press-difference and pumps' numbers is feasible for middle and small air conditioning systems.
