  1. Dr. Gerhard Kunze SolarFrost Research & Development www.solarfrost.com

  2. SolarFrost History SolarFrost provides research and development (R&D) services for cooling machines powered by thermal energy, provided by solar collectors, district heating or waste heat. SolarFrost cooling machines replace conventional air conditioning products powered by non-renewable energy sources. Our vision is to make this new technology available worldwide, to the benefit of consumers and the environment 1996 Development aid co-operation project in 1996 between Austria and Tanzania to develop a solar refrigeration system for milk 2001 Foundation of SolarFrost International Ltd. Company financed by an ecologically motivated fund from Hong Kong 2001-04 Various patents for different developments 2004 - Nomination for ”The EU Co-operation Award for Sustainable Development” - Finalist for the World Technology Awards 2005 - New office and laboratory in Purkersdorf near Vienna - Foundation of SolarFrost Forschung & Entwicklung GmbH

  3. SolarFrost PrototypesClassic Tubular Model SolarFrost Cooling Machine with Tubular Heat Exchangers (2kW)

  4. Machine with Plate Heat Exchangers

  5. Cylinder Machine

  6. Ammonia-Absorption-Cooling

  7. Bypass System for Low Cooling Temperatures and High Back-Cooling Temperatures

  8. Efficiency of „Bypass-System at a Cooling Temperature of 15°C

  9. Absorption Heat Recoveryin the P-T Diagram COP > 1 is possible! pure

  10. pure Conventional Ammonia Absorption hardly allows Absorption Heat Recovery COP < 1

  11. Bypass System with Absorption Heat Recovery Combination of Bypass System with Absorption heat Recovery: Theoretical COP at heating temperature 65°C: COP = 1,5 Expected: COP > 1,2
