节能要求我们制定最佳泵送能量的理想标准清单，设计一个充分利用潜在节能的系统，并检查任何虚构的或实际的问题，以确定是否有新的或现有的概念和技术可用，或是否可以开发出新的或现有的概念和技术来解决这些问题，而不会对相关的能源子系统施加能源惩罚，也不会增加寿命周期成本或初始成本。我们将从100%满载（FL）时的高效变速泵（VSP）设计开始，然后添加通常用于改善操作、控制安全或成本的功能，说明其对能耗的不利影响。 引用:ASHRAE交易，第81卷，第一部分，新泽西州大西洋城

Energy conservation demands that we establish a list of desirable criteria for optimum pumping energy, design a system which fully utilizes the potential savings, and examine any mythical or actual problems to decide whether new or existing concepts and techniques are available or can be developed to resolve the problems without imposing energy penalties upon associated energy subsystems and without increasing life-cycle cost or first cost.We shall start with an efficient variable speed pumping (VSP) design at 100% full load (FL), then add features commonly employed to allegedly improve operation, control safety, or cost, illustrating their adverse effect upon energy consumption.
