The 8th Conference on Ammonia and CO2 Refrigeration Technologies takes place in Ohrid, Macedonia, on 11-13 April.
The climate change is a global issue with catastrophic consequences which remind us almost every day. There are alarming projections of GHG emissions including HFCs. In Europe the Regulation No 517/2014 on F-gases has been introduced with many restrictions and gradually phase-down. The 28 Meeting of the Parties (in 2016) adopted an amendment to the Montreal Protocol for gradually phase-down of HFCs (from 2019 to 2047) to achieve 85% reduction. Recently, new HFC refrigerants (named HFOs) with low GWPs are appeared on the market. The choice of refrigerant (and technology) has become a very complicated issue. Of all refrigerants applied today, ammonia and CO2 are the oldest that have been used since the 19th century. The topics of the conference are: design of modern ammonia and new CO2 systems and technological innovations, improving energy efficiency, various applications, technical guidelines and safety regulations. It is very clear: by using more ammonia and CO2 refrigerants, we are employing environmentally friendly technologies.
