Description

Bio: Mr. Fly has over 40 years of experience as a Researcher, Consulting Engineer, Contractor, and Manufacturer in the HVAC Industry. He is currently the Executive Director of the Norman Asbjornson Innovation Center & Laboratory, (NAIC) at AAON, Inc. in Tulsa, Oklahoma. He served as Director of Engineering of AAON for 11 years prior to taking that position. He holds a Bachelor of Science in Engineering Physics from Missouri State University and is a Licensed Professional Engineer in two states. Steady On the Throttle - Part Load Compressor Technologies and Applications There are many advantage of variable capacity compressors in both energy reduction and precision space temperature and humidity control. Several technologies are available to achieve variable compressor capacity modulation. It is not surprising that ultimate in efficiency, true variable speed compressors, come with the most complex and least robust system of control and operation. Due to the parasitic energy use of variable speed drive devices, they are also less efficient at full speed by 3-5%. Both the digital and two step scroll compressor offer improved efficiency with reduced complexity in the areas of control and less long term equipment life issues regarding oil circulation or resonance issues in the equipment or building structure. This presentation will discuss how these technologies work as well as the efficiency and space control that can be achieved with each by: 1. Discovering why variable capacity control is desirable, necessary and critical to certain applications 2. Understanding the different types of compressors that are most commonly used in unitary HVAC equipment 3. Review the different methods of capacity modulation and the pros and cons of each 4. Analyze the different tradeoffs on each modulation type in terms of cost, precision, efficiency, control complexity, and equipment life .
