本文回应了ASHRAE期刊上的一封信，其中一位读者（Boghosian 2010）质疑如何控制冷却塔风机，并参考了ASHRAE《暖通空调应用手册》（ASHRAE 2007）第41.12至41.16页，质疑如何实施该手册的方法。ASHRAE的作者（Dieckmann 2010）建议读者运行一个“综合模型”（Schwedler 2009）来回答他的问题。本文通过theASHRAE手册HVAC应用（ASHRAE 2007）第41.16页示例1中四台冷水机组/塔设备的工厂模拟数学模型回答了读者提出的问题，表明没有风扇控制的24 kW风扇塔比有风扇控制的40 kW风扇塔效率更高。本文还简要讨论了如何使用仿真模型来进行优化- 调整电厂运行，还表明电厂运行不良可能导致比塔风机控制不良更多的能源浪费。论文最后提出了一个问题:仿真建模在寻求更有效地设计和运行暖通空调系统方面有价值吗？如果有，如何将仿真建模融入暖通空调领域？引文:伊利诺伊州芝加哥ASHRAE Transactions第118卷第1部分

This paper responds to a letter in ASHRAE Journal in which a reader (Boghosian 2010) questioned how to control cooling tower fans and referred to pages 41.12 through 41.16 ofASHRAE Handbook-HVAC Applications(ASHRAE 2007), questioning how to implement the Handbook's approach. The ASHRAE author (Dieckmann 2010) suggests the reader run a "comprehensive model" (Schwedler 2009) to answer his question. This paper answers the question posed by the reader with a plant simulation math model of the four chiller/tower plant of Example 1 on page 41.16 of theASHRAE Handbook-HVAC Applications(ASHRAE 2007), showing that a 24 kW fan tower without fan control can be more efficient than a 40 kW fan tower with fan control. This paper also briefly discusses using a simulation model to fine-tune plant operation and also shows that poor operation of a plant can result in significantly more energy waste than poor tower fan control. The paper ends with the suggested question: does simulation modeling have value in the quest for more efficiently designed and operated HVAC systems, and if it does, how does one pursue incorporating simulation modeling into the HVAC community
