本演示回顾了在空气侧盘管、冷水机冷却器和冷凝器、热水锅炉和暖通空调系统的其他传热部件上应用变速泵的潜在好处。对特征容量/流量关系进行了说明和讨论。注意流量减少量的限制。使用当前系统设计实践的典型示例，与其他容量控制方法进行了经济比较。引文:研讨会，ASHRAE交易，1985年，第91卷，pt。1B芝加哥

This presentation reviews the potential benefits of applying variable-speed pumping to airside coils, water chiller coolers and condensers, hot water boilers, and other heat transfer components of an HVAC system.Characteristic capacity/flow relationships are illustrated and discussed. Limits on the amount of flow reduction are noted. Economic comparisons with other methods of capacity control are provided, using typical examples of current system design practice.
