Welcome to the press room of eurammon - please find our latest press releases listed below.
It is one of the key dates for the refrigeration and air-conditioning industry: in June 2020, operators, planners, system enigneers and an interested trade audience will come together for the eurammon Symposium 2020.
The symposium will adress questions on the topic of "Heating and Cooling with Natural Refrigeratants - a Way to Decarbonization." The focus this year will be on heat pumps using natural refrigerants and the associated possibilites for waste heat recovery. International experts show how the use of heat pumps with natural refrigerants constributes to meeting increased ecological requirements. Participants will gain insights into current legislation and technical regulations, discuss new solutions for heat pumps using natural refrigeratns and attend the Natural Refrigeration Awards ceremony.
Every two years, eurammon rewards young scientists for pioneering research in the field of natural refrigerants. This year, the Natural Refrigeration Award prize of €5,000 was awarded with support from the Technical University Braunschweig and the Czech trade journal Chlazení. The prizes were awarded to the three winners on 22 June 2017 during the eurammon Symposium, where they were also able to present and discuss their research work and results relating to the use of natural refrigerants such as ammonia and CO2 with the international expert audience at the symposium.
The eurammon Symposium 2017 was held in Schaffhausen, Switzerland, on 22nd and 23rd of June, 2017. The speakers gave altogether ten lectures on current trends and developments in refrigeration and air-conditioning technology, with a special emphasis on "Small Applications < 200 kW with Natural Refrigerants". As in previous years, the lecture event was fully booked with about 70 participants from 16 countries. "The European F-Gases Regulation and the Kigali agreement have brought natural refrigerants more than ever into the focus of the refrigeration and air-conditioning industry", explained Bernd Kaltenbrunner, Chairman of eurammon. "The growing demand for the classic large applications is currently also accompanied by a trend to using natural refrigerants in smaller plants with capacity of less than 200 kW – not just in refrigeration plants but also in heat pumps and air-conditioning systems", said Kaltenbrunner. Besides legal framework conditions and safety aspects, the key symposium topic also illustrated pioneering application examples. A special emphasis was placed on small applications with hydrocarbons such as propane.
From the CFC ban and the Kyoto protocol to the EU regulation on fluorinated greenhouse gases – more and more national and international laws are limiting the use of refrigerants that are harmful to the climate. Against this background, operators are confronted with the increasingly urgent question of the ecological and economical characteristics of refrigeration methods. With an ODP of 0 and a GWP between 0 and 3, natural refrigerants are particularly environment-friendly, and also a safe option for the users – no use restrictions are to be expected for the foreseeable future.
At first glance, the initial investment costs for systems using natural refrigerants often look off-puttingly high – but they should always be considered in context: A detailed analysis of the life cycle costs shows that natural refrigerants are also often the best choice in terms of economy. eurammon member Rob Lamb, marketing director at Star Refrigeration Ltd., explains in detail what the important factors are for an economic calculation.
