Researchers develop enhanced refrigerant compressor


A compressor design from Purdue University innovators proposes a new drive mechanism for compressors used in residential homes, supermarkets, other large buildings, trains, cars and refrigerated trucks.

Based in Indiana, the university researchers created a new design to create the orbiting motion for scroll compressors, which are commonly used in cooling systems of different sizes. 

The new design relies on a gear mechanism to create the orbiting motion of a scroll wrap within another stationary scroll wrap to compress a refrigerant. 

“In the conventional scroll compressor setup, typically an Oldham coupling is used, which is based on a metal to metal sliding contact,” said Leon Brendel, a Ph.D Student in Mechanical Engineering.
