对美国中西部的一家大型轮胎制造商进行了一项研究，以确定节能领域的存在，并进行了计算，预测了购买和安装节能技术的成本、每年节省的能源量，以及减少能源使用带来的年成本节约。所检查的节能领域包括轮胎模具的隔热、热电联产、冷冻水泵上的变频驱动器（VFD）、减压涡轮机（PRT）和吸收式制冷。该研究预测，在使用多年后绝缘层已被移除的情况下，对轮胎模具进行绝缘，以及在设施的冷冻水泵上安装VFD，都是非常有利的。该研究建议对使用PRT代替当前压力进行更多调查- 在较低压力下提供蒸汽的减压阀。使用热电联产是一项重大变革，需要对基础设施进行重大改造，并使设施停工，但该公司预计将大幅节约成本。吸收式制冷可用于从蒸汽锅炉的废热中成功地生产冷冻水，但与每年节省的成本相比，最初的成本并没有造成这一重大变化。引用:德克萨斯州达拉斯ASHRAE Transactions第119卷第1部分。

A study of a large midwestern U.S. tire manufacturer was performed to determine where areas of energy conservation exist, and calculations were made predicting the costs of purchasing and installing energy-saving technology, the annual amount of energy saved, and annual cost savings from reduced energy use. The areas of energy conservation that were examined included insulation of tire molds, cogeneration, variable-frequency drives (VFDs) on the chilled-water pumps, a pressure-reduction turbine (PRT), and absorption refrigeration. The study predicted that it was very advantageous to both insulate tire molds where insulation had been removed over years of use and to install VFDs on the chilled-water pumps in the facility. The study suggested more investigation of the use of a PRT in place of the current pressure-reduction valve that provides steam at a lower pressure. Using cogeneration was a significant change that would require major infrastructure changes and downtime to the facility, but it predicted that significant cost savings would result. Absorption refrigeration could be used to successfully produce chilled water from the waste heat of the steam boilers, but the initial cost compared to the annual cost savings did not make this asuggested change.
