The center developed a novel test method for measuring oil retention, applying it to a wide range of refrigerants and miscible and non-miscible lubricants. The resulting correlations are predicting oil retention in systems. Then, CEEE, together with one of its sponsors, developed an oil concentration sensor.  We’ve created a test facility and method for the measurement of vapor compression system performance under dynamic conditions. We test automotive air conditioners over an entire drive cycle — or a route traveling from Maine to Florida — without ever leaving the lab.

CEEE faculty and graduate students are working for the following projects:

  • Transient performance of secondary loop systems
  • HFC two-stage cycles with vapor injection compressor
  • Plate heat exchanger performance evaluations
  • Water retention on fin surfaces
  • Separate latent and sensible cooling
  • Solar cooling technologies
  • Industrial CHP applications
