Ammonia and CO2 Refrigeration International Conference - Ohrid 2021 -

Thursday 16th September 2021 to Friday 17th September 2021

International IIR co sponsored conference

The choice of refrigerant (and technology) has become a very complicated issue. In the RAC industry, confusion and uncertainties related to working fluids in many applications are continuing. In addition, there are many groups with diverging interests: chemical companies, manufacturers of equipment, distributors, users, environmental organizations, politicians and the public.

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.

The previous eight Ohrid conferences were very successful, so we look forward to the 9th Conference on Ammonia and CO2 Refrigeration Technologies
