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-operationAward for Sustainable Development”
- Finalist for the World Technology Awards 2005 - New office and laboratory in Purkersdorf near Vienna
- Foundation of SolarFrost Forschung & Entwicklung GmbH

Absorption Heat Recoveryin the P-T Diagram
pureCOP > 1 is possible!
Conventional Ammonia Absorption hardly allows
Absorption Heat Recovery
pureCOP < 1
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
