为了为使用不间断电源（UPS）的设施确定HVAC设备的尺寸，需要准确估计这些设备产生的热负荷。提出了一种UPS的功耗模型。功率损耗模型的基础是UPS的效率。对不同的UPS配置进行了分类，并给出了相应的效率，它是负载的函数。共展示了五种不同的配置，并提供了四种不同的效率模型。模型中使用的数据来自一项公共赞助的研究。模型与从制造商网站获得的UPS效率信息进行了比较，效率模型与制造商数据之间的一致性被证明是合理的。功率损耗模型是RP工作范围的一部分- 1395.引文:ASHRAE交易，第117卷，第2部分，魁北克省蒙特利尔

In order to size the HVAC equipment for facilities using uninterruptible power supplies (UPS), an accurate estimate of the heat load produced by these devices is required. A model for the power dissipation of UPS is presented. The basis of the power loss model is the UPS efficiency. Different UPS configurations are classified and a corresponding efficiency, which is a function of load, is presented. A total of five different configurations are illustrated and a total of four different efficiency models are provided. The data used in the models are obtained from a publically sponsored study. The models are compared with UPS efficiency information obtained from manufacturer Web sites and the agreement between the efficiency models and the manufacturer data is shown to be reasonable. The power loss models were part of the work scope for RP-1395.
