The conclusion in multiple scientific reports on the subject concludes that the main barrier to using water as a refrigerant has been that no one has been able to make a turbo-compressor capable of moving the enormous amounts of steam necessary for a water vapor compression process.
Our inventor, Mr. Gunnar Minds, diversified work experiences in the cooling industry, and the Danish Institute of Technology over the last 50 years exposed him early on to the environmental advantages of using water as a refrigerant back in the late 1970'.
Over the following years, in the 1980' and 1990' Gunnar Minds was involved in developing and using heat pumps and Ice Slurry in commercial applications.
In 1995 he designed and helped build a 2 MW Chiller Plant at LEGO's main production facility in Billund, Denmark. The Chiller Plant used water as the refrigerant and was the first of its kind. For this project, the European Commission awarded Gunnar Minds an Environmental 1st Prize in 1996.
In 2020 Gunnar Minds, at 83, stepped out of his retirement to focus on making the first turbo-compressor in the world using water as the process driver and refrigerant. 2 years later, the new technology was born.
