鉴于暖通空调泵送过程中节能的必要性，本文旨在展示同一冷冻水系统的广泛能耗。四种不同泵送方案的年泵送能耗从定容泵的570000 kWh到变速建筑泵的177000 kWh不等。本文介绍了四种不同的泵送系统，以及用于计算年能耗的方法和程序。引文:研讨会，ASHRAE交易，1983年，第89卷，pt。华盛顿特区2B。

In recognition of the need for energy conservation in HVAC pumping processes, this paper was written to demonstrate the broad energy consumptions that occur same chilled water system. Annual with four different pumping schemes for the consumptions of pumping energy vary from 570,000 kWh for constant volume pumping to 177,000 kWh for variable-speed building pumps. This paper describes the four different pumping systems and the methods and procedure used to calculate the annual energy consumptions.
