ABOUT THE CONFERENCE  

The concentrations of greenhouse gases in the atmosphere are increasing continuously. There are alarming projec-

tions 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 27 Meeting of the Parties (in 2015) decided to negotiate for phase-down of HFCs within the Montreal Protocol. 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. In the RAC industry, confusion and un-

certainties 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.  

After several conversions CFCs -> HCFCs -> HFCs -> HFOs(?), the global trend towards using natural refrigerants is

intensifying. There are very positive signals in Europe and some parts in the world where expanding use of ammonia, carbon dioxide and hydrocarbons in various applications is occurring. We will eliminate all uncertainties in the future regarding both Protocols and environmental regulations applying to natural refrigerants.  

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.  

The previous six conferences were very successful, so we look forward to the 7th Conference on Ammonia and CO2 Refrigeration Technologies. Use the opportunity to see the beautiful city of Ohrid and Ohrid Lake!

OHRID  

Ohrid is a city-museum with numerous archaeological treasures, with a number of early Christian basilicas, a great number of churches, luxurious mosaics, valuable archaeological sites and an antique theatre, which confirm that Ohrid was a cultural centre of the ancient era.  

Lake Ohrid, the blue Macedonian pearl, is one of the oldest and best-preserved lakes in the world. It lies at an altitude of 695 m, has an area of 358 km² and maximum depth of 289 m. The crystal-clear lake water and the unpolluted environment afford a breath of untouched nature.  

Ohrid and Lake Ohrid have been named a world cultural and natural heritage listed city under the protection of UNESCO since 1980.  

Over the centuries, an enormous and colourful heritage of beautiful architecture, crafts and traditions has evolved. Combined with its scenic lake and mountainscape, interesting town and village architecture, local hospitality, climate and delicious fresh food, a visit to the Ohrid area will be deeply rewarding.

International Institute of Refrigeration

The International Institute of Refrigeration (IIR) is the only independent intergovernmental science and technology based organization which promotes knowledge of refrigeration and associated technologies that improve quality of life in a cost-effective and environmentally sustainable manner including: Food quality and

safety from farm to consumer ; Comfort in homes and commercial buildings ; Health products and services; Low temperature technology and liquefied gas technology ; Energy efficiency; Use of non-ozone depleting and low global warming refrigerants in a safe manner.  

Members of the IIR include Member Countries. Member Countries take part in IIR activities via the commission members they select. Moreover, companies, laboratories, universities… can become corporate or benefactor members of the IIR.

The IIR provides its members with tailored services meeting a wide range of member-country, national and international organizations, decision-makers, researchers and refrigeration practitioners needs.

The head office of the IIR and its entire staff are located in Paris. Find out more about the IIR on: www.iifiir.org.
