Title: Highly efficient, thermally-powered ejector cooling and refrigeration system
Author: Cheng, Peng, 1979-

Abstract: ThermAvant is developing its patent-pending, thermally-driven refrigeration technology that uses an advanced ejector vapor compression cycle to convert 200-350F heat into useful cooling at unprecedented efficiencies. Co-invented by ThermAvant and the University of Missouri, the HHP-JET technology is currently funded by the U.S. Army to convert the exhaust heat from gas-powered generators to provide air conditioning to soldiers in forward operating bases in order to lower generator fuel consumption (and cost) by up to 50%. Future applications include natural gas-powered HVAC units, vehicle exhaust passenger cooling, and solar thermal-driven chillers. The HHP-JET utilizes low-to-medium grade heat to convert the pressure energy of a propellant into a supersonic, low pressure jet stream that evaporates, entrains and compresses a low pressure, low temperature refrigerant to remove heat from the controlled environment. The HHP-JET has few moving parts; is built from relatively low cost components; and avoids the energy, environmental and economic challenges posed by status quo electrically-powered air conditioners. Building cooling is the number one use of grid-tied peak demand electricity, and the worldwide air conditioning equipment market is ๖ billion per year. ThermAvant expects to begin installing commercial HHP-JET systems within 24 months in order to penetrate this very large market opportunity. Potential Areas of Applications: waste heat-or natural gas- powered space cooling, Vehicle exhaust-powered air conditioning, Water desalination. Patent Status: Patent Pending. Inventor(s): Dr. Hongbin "Bill" Ma; Dr. Peng Cheng; Mr. Joe Boswell. This presentation was an Engineering elevator pitch at the Missouri Technology Expo 2011.
