本文提出了一种新的一次二次系统泵速控制方法。控制分配（二次）泵的速度，以保持优化的系统阻力，使盘管阀打开。系统阻力可通过泵头和水流量获得，水流量由最近开发的泵水流量站（PWS）计算。PWS使用泵头、泵速和泵性能曲线测量水流量。该方法在实际暖通空调系统中得到了实验验证。本文给出了一个在连续调试实践中应用这种新方法的实例。案例研究表明，PWS可以控制泵速，以保持优化的系统阻力。它还可以以最小的安装和维护费用测量水流量并持续监测能耗。 结果表明，新技术可以显著节省泵功率，提高泵效率。单位:投资:ASHRAE交易，第113卷，pt。2.

A new pump speed control method for the primary-secondary system is developed and presented in this paper. The distribution (secondary) pump speed is controlled to maintain the optimized system resistance to make the coil valves open. The system resistance can be obtained by the pump head and the water flow rate, which is calculated by the recently developed pump water flow station (PWS). The PWS measures the water flow rate using the pump head, pump speed, and pump performance curve. This method was proved experimentally in real HVAC systems. A case study is presented in this paper for application of this new method in a continuous commissioning practice. The case study shows that the PWS can control the pump speed to maintain optimized system resistance. It can also measure the water flow rate and monitor energy consumption continuously with minimal installation and maintenance expense. The results show that the new technology can save a significant amount of pump power and increase pump efficiency.Units: I-P
