说明免费冷却系统的潜在节能量几乎完全取决于整个系统设计和系统中使用的设备选择。指出一般来说，设计师必须在更高的设备成本和更大的节能机会之间取得平衡。这些节约以及相关成本是可以合理量化的，因此设计师可以在可靠信息的指导下做出明智的选择。关键词:免费冷却，冷却塔，节能，设计，选择，设备，成本。引用:研讨会，ASHRAE Trans。1994年，第100卷，第一部分

States that the amount of potential energy savings available with free cooling systems depends almost totally on the overall system design and on the selection of equipment for use in the system. Points out that in general the designer must balance higher equipment cost with greater opportunity for energy savings. These savings - and their associated costs - are reasonably quantifiable so the designer can make intelligent choices guided by reliable information.KEYWORDS: Free cooling, cooling towers, energy conservation, designing, selecting, equipment, costs.
