Smaller More Efficient Refrigeration Equipment that Uses Available Heat to Power Cooling


The University of Florida is seeking companies interested in commercializing film-based compact absorption refrigeration equipment that repurposes heat from industrial processes to more efficiently run refrigerators or air conditioners at low cost. Absorption refrigeration systems (ARS) also called absorption chillers have remained relatively unchanged since their invention more than 150 years ago. The market is only beginning to appreciate the ecofriendly aspect of absorption chillers which repurpose energy that would otherwise be wasted. Absorption chillers are powered by waste heat from industrial or residential sources. They can also run on solar energy. Available absorption chillers with cooling capacities of 10-15 kW generally rely on shell and tube absorbers that weigh 880 pounds or more making them too large and unwieldy for many buildings. Researchers at the University of Florida have developed an inexpensive absorption refrigeration system that is more compact uses fewer components and performs better than existing technologies. Application: Absorption cooling technology that employs ultra-thin liquid film for less expensive more efficient refrigerators and air conditioners.


1) Reduces size allowing the use of the ARS in smaller spaces 2) Requires fewer components reducing associated costs and improving reliability 3) Uses an environmentally friendly process reducing CO2 emissions and eliminating harmful chemicals such as Freon 4) Enhances output improving overall efficiency
