Seminar 11 -- How Hard Can It Be? Simulating and Optimizing Compressors for Next Generation Systems and Refrigerants PDF

2024 ASHRAE Annual Conference

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

This seminar aims to share the complexity and beauty of compression through the lens of the challenges associated with the development of compressors for next generation equipment. To this end, the presentations explore several modeling methods that are used for development and optimization of both positive displacement and centrifugal compressors as well as application and refrigerant selection. This includes mechanistic chamber models and CFD analysis used for compressor development and optimization. Additionally explored are advanced system-level models that are utilized for simulating compressor behavior installed in a piece of equipment.
