eurammon Symposium 2017 “Small Applications <200 kW with Natural Refrigerants”

Frankfurt, 10th February 2017 – Great potential for systems in a small capacity ranges: On June 22 and 23 2017, operators, planners, manufacturers and interested expert visitors will meet at the eurammon Symposium Schaffhausen, Switzerland. Small scale applications for refrigeration and HVAC that are operated with natural refrigerants will be the focus of the event. This year´s highlight will be the use of hydrocarbons. Besides valuable information about statutory regulations, energy efficiency and specific requirements for the safe use of natural refrigerants, the participants will get a fascinating insight into successful practical examples that will be presented by international experts.

 

Large refrigeration plants operating with natural refrigerants like ammonia have been a long-standing standard in the industrial refrigeration industry. But the use of natural refrigerants is also gaining ground in small refrigeration systems due to the current legal environmental framework and new technological possibilities. "Especially for small applications up to 200 kW, natural refrigerants are not only environmentally-friendly and sustainable but also a very efficient economic solution," explains Bernd Kaltenbrunner, chairman of eurammon. By means of precise practical examples, the speakers will illustrate just how economically efficient systems can be operated with natural refrigerants, and in which application fields refrigeration systems operating with hydrocarbons, for example, are already successfully established.

 

Besides exciting lectures, eurammon will offer an interactive workshop with four different groups and topics:

 

Group Topic Moderation
1 Hydrocarbons in Comparison to A2L Refrigerants Dr. Frank Rinne
2 Most Promising Commercial Applications for Hydrocarbons Hermann Renz
3 Training and Education for Hydrocarbons Prof. Dr. Alexander Krimmel
4 Small Applications with Ammonia Daniel McDougall

Natural refrigerants: small applications with great potential

Frankfurt (Main), 10th July 2017 – The eurammon Symposium 2017 was held in Schaffhausen (Switzerland) on 22 and 23 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.

Legal framework conditions, advanced safety standards and efficient plant design reinforce the use of natural refrigerants
The first day of the symposium looked at the environmental and safety requirements that have to be met by refrigeration and air-conditioning technology with natural refrigerants. Henry Wöhrnschimmel from the Federal Office for the Environment FOEN (Switzerland) informed the interested audience about the current legal situation in the symposium's host country, together with the pending second amendment of the Swiss Chemicals Reduction Ordinance (ChemRVV) with even stricter regulations on the use of synthetic refrigerants impacting on the climate. The environmentally friendly properties of natural refrigerants such as ammonia or CO2 therefore make them increasingly attractive for companies and operators.
The eurammon members Frank Rinne (Emerson Climate Technologies GmbH) together with Thorsten Lerch and Ralf Catanescu from the Federal Technical College of Refrigeration and Air Conditioning Technology (Bundesfachschule Kälte-Klima-Technik in Maintal, Germany) spoke on the safety requirements for natural refrigerants, showing optimum ways of implementing corresponding plants in the framework of the existing regulations. Fascinating details and insights into energy efficiency and profitability were provided in the lecture by Georges Hoeterickx (EVAPCO Europe BVBA), while Hermann Renz (BITZER Kühlmaschinen GmbH) presented the selection criteria for suitable components in commercial refrigeration systems with refrigerants R290 and R1270.

A look at successful practice – small applications are the next big thing
Attention particularly on the second day of the symposium turned to specific reference projects which were the subject of intensive discussions about relevant parameters such as plant design, component selection and operating costs. Johann Herunter (FRIGOPOL Kälteanlagen GmbH) and Kevin Dujardin (Alpiq InTec West AG) showed the impacts of phasing out various refrigerants on supermarket refrigeration, industry refrigeration and small business applications – examining why refrigeration systems with propane are an efficient, sustainable solution particularly in the small and medium capacity range.
Michael Freiherr (Güntner GmbH & Co. KG) illustrated the advantages of adiabatic air pre-cooling of gas coolers in trans-critical CO2 refrigeration plants for supermarkets, with various examples indicating the potential and the operating limits. Innovative, smart control functions for cutting operating costs and enhancing operational safety met with lively interest in the audience. The way a brewery in Munich's north-east cools and dries biogas in a liquid chiller with just 1 kg propane was demonstrated in the lecture given by Karl Huber (HKT Huber-Kälte-Technik GmbH). Ammonia is also growing increasingly significant as a refrigerant for HVAC and freezer systems: as shown in the lecture by Daniel McDougall (Star Refrigeration Ltd.), innovative DX technology makes it possible to reduce necessary refrigerant charge by up to 79% while still achieving the very high efficiency levels typical for ammonia systems.

It is no longer just existing and pending restrictions on synthetic refrigerants that drive the growing demand for systems that run on natural refrigerants. "The market is developing increasingly efficient components and improved system designs with low charge of refrigerants", explained Bernd Kaltenbrunner. "Besides future viability, the plants also score with higher efficiency and corresponding reductions in operational costs so that the initial investment soon pays off", said the eurammon Chairman. The growing number of successful reference projects in the <200 kW range also enhances an awareness for efficient applications that protect the environment and are suitable for long-term use, thus accelerating the market transformation towards using refrigeration and air-conditioning systems with natural refrigerants.
