Improving Fan System Performance: A Sourcebook for Industry
This sourcebook is designed to provide fan system users with a reference outlining opportunities to improve system performance. It is not intended to be a comprehensive technical text on improving fan systems, but rather a document that makes users aware of potential performance improvements, provides some practical guidelines, and details where the user can find more help. The sourcebook is divided into three main sections and appendices. Section 1: Introduction to Fan Systems For users unfamiliar with the basics of fans and fan systems, a brief discussion of the terms, relationships, and important system design considerations is provided. This section describes the key factors involved in fan selection and system design and provides an overview of different types of fans and the applications for which they are generally used. Users already familiar with fan system operation may want to skip this section. The key terms and parameters used in selecting fans, designing systems, and controlling fluid flow are discussed. Section 2: Performance Improvement Opportunity Roadmap This section describes the key components of a fan system and the opportunities for performance improvements. Also provided is a figurative system diagram identifying fan system components and performance improvement opportunities. A set of fact sheets describing these opportunities in greater detail follows the diagram. These fact sheets cover: 1. Assessing Fan System Needs 2. Fan Types 3. Basic Maintenance 4. Common Fan Systems Problems 5. Indications of Oversized Fans 6. System Leaks 7. Configurations to Improve Fan System Efficiency 8. Controlling Fans with Variable Loads 9. Fan Drive Options 10. Multiple-Fan Arrangements 11. Fan System Economics Section 3: Programs, Resources, and Contacts Section 3 provides a directory of associations and other organizations involved in the fan marketplace, along with a listing of the resources, tools, software, videos, and workshops.
