Overview:

This innovative approach eliminates the reliance on potentially harmful refrigerants while significantly improving energy efficiency of the overall system for better heat transfer by utilizing low-cost, compressible materials with zero or near zero global warming potential. Unlike traditional vapor compression systems, which rely on refrigerants that contribute to the global greenhouse effect, our patented approach addresses essential challenges related to cost, efficiency, and scalability, positioning this barocaloric system as a next-generation alternative.

Highlights:

  • Demonstrated an estimated 20% higher coefficient of performance (COP) when compared to other conventional vapor compression systems, with the potential to achieve significantly higher COPs using already existing materials
  • Eliminates the need for any capacity for liquid coolant leakage failures and any additional peripheral, refrigerant monitoring equipment, which reduces size, weight, and routine maintenance requirements
  • Cost-effective heat pump capable of conditioning residential and industrial applications in a variety of climates and even low or zero gravity environments while facilitating efficient thermal management
  • Utilizes compact, compressible solid-state refrigerants with zero global warming potential

Benefits: 

Our barocaloric, solid-state heat pump represents a significant advancement in sustainable thermal management. A significant advantage of using this solid-state heat pump is that it can have the ability to operate at higher efficiency in low or zero gravity environments. The patented technology would potentially increase the overall specific heating and cooling power versus conventional heat pumps.

Applications:

This innovative technology for refrigeration and air conditioning manufacturers offers more sustainable and cost-effective refrigeration technologies. The system operates at a wide range of temperature options for both residential and industrial applications, while reducing carbon footprints. Along with other commercial applications potentially in use in HVAC, refrigerators, water coolers, ice makers, and beverage chillers.
