Evaporative systems are probably the oldest technology for thermal comfort. However, they still an essential in food industry, environments comfort, and even cooling data centers. Standards have been improved to compare energy efficiency of this type equipment. Using AHRI concepts with temperature from 29 most populous cities world, EvaCOP index was created temperatures that easier simulate tha...

Power plant performance can decrease along with its life span, and move away from the design commissioning targets. Maintenance issues, operational practices, market restrictions, financial objectives may lead to that behavior, knowledge of appropriate actions could support system retake original performance. This paper applies unsupervised machine learning techniques identify operating pattern...
