'Green' Chiller Technology Rolled Out For Earth Day
Penn State acousticians put their new prototype for a compact chiller, based on "green" technology that substitutes sound waves for environment-damaging chemical refrigerants, on first public display in conjunction with Earth Day in New York City.
The roll-out took place at a Ben & Jerry's scoop shop in New York City where the chiller was hooked up to a standard ice cream sales freezer cabinet and successfully kept the creamy merchandise in delicious condition. Ben & Jerry's partnered with Penn State, with financial and scientific support from its parent company, Unilever, to develop a more environmentally friendly prototype freezer cabinet.
