Efficient Energy Modeling for Sustainable Engineering: Refrigerants & Cooling Systems Workshop

DESCRIPTION

Join Shah Smith and Associates for an informative workshop on Rapid and Early Energy Modeling tailored for engineers focused on sustainability. Scheduled for March 8th at 6 PM in ETC 2.132, this session will cover essential topics including cooling cycles, system components, and the properties of various refrigerants. Learn how to enhance efficiency through multistage compression cycles, control compressor discharge temperatures, and manage low evaporating temperatures essential for cryogenics. Don't miss this opportunity to elevate your knowledge in sustainable energy practices!

  11. Rotary Compressor

  12. Refrigerants

  13. What are desirable properties of refrigerants? • Pressure and boiling point • Critical temperature • Latent heat of vaporization • Heat transfer properties • Viscosity • Stability

  14. In Addition…. • Toxicity • Flammability • Ozone-depletion • Greenhouse potential • Cost • Leak detection • Oil solubility • Water solubility

  15. Refrigerants • What does R-12 mean? • ASHRAE classifications • From right to left ← • # fluorine atoms • # hydrogen atoms +1 • # C atoms – 1 (omit if zero) • # C=C double bonds (omit if zero) • B at end means bromine instead of chlorine • a or b at end means different isomer
