ASHRAE Journal - February 2009 - (Page 6) Bitzer’s new offering in the low-temperature sector drew interest at Chillventa. Their new semihermetic screw compressor HSN8591 offers all the benefits of the HSN85 series, but with a larger displacement and special design to meet performance requirements for the low-temperature sector. Inaugural Chillventa Is German Showcase NÜRNBERG, Germany— The Germans might have a word for visitors’ reaction to the Chillventa trade fair that took place here Oct. 15 – 17, 2008. After all, they have a word for almost everything else. “Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz” is the name of a German beef labeling law. How about “arzneimittelausgabenbegrenzungsgesetz,” which means “area of responsibility.” Hungry?Try “oberammergaueralpenkräuterdelikatessenfrühstückskäse,” a breakfast of cheese and mountain herbs. Ger mans could well be calling Chillventa “spektakulärekälteklimamessemitstarkerindustrieunterstützung,” or a super successful trade fair with wide support from industry. No such word actually exists, but perhaps it should because that seemed to be the view of the 30,000 trade visitors from more than 90 countries who visited Chillventa and the stands of its 804 exhibitors. Although this was the fair’s inaugural edition, which 6 ASHRAE Journal now begins a biennial cycle, it actually replaces a German trade fair focused on refrigeration that had been held annually for 20 plus years. There’s no question that German manufacturers supported the launch. “The mood among the exhibitors and visitors was positive and relaxed, and the talks were at a recognizably high level. We achieved all the targets set for this exhibition. All the partners we had invited to Chillventa were present,” said Thomas Ernst, director of corporate communication at Bitzer. One noticeable difference between U.S. trade fairs and their German counterparts is the number of technical advisers present at the German stands. At Chillventa, the focus was clearly technical and operational guidance, with emphasis on energy efficiency and good environmental stewardship. “Some 4,000 visitors from over 30 countries came to our stand,” said Bernd Gantner, managing director of Güntner. ashrae.org Total sales of building services systems in Germany amount to around 60 billion Euros in 2007. • Germany, with total sales of almost 500 million Euros in chillers, ventilation and air-conditioning equipment and fan convectors, surpassed Italy as the European leader in 2007. • Germany leads in the sales of cooling ceilings, installing about 650 000 m² (7,000 ft2) worth some 100 million Euros annually. • Two European standards published in summer 2007, DIN EN 13779, “Ventilation for Non-Residential Buildings” and DIN EN 15251, “Indoor Environmental Input Parameters for Design and Assessment of Energy Performance of Buildings,” strongly influence Germany’s market. The standards specify the intake volume of outside air, room temperatures, and humidity to be maintained and specify design to minimize the energy requirement. • The German Energy Conservation Act (EnEV) in force since October 2007 defines the energy efficiency of central ventilation and air conditioning systems. EnEV stipulates that the energy requirement of the fan in a ventilation system must not exceed a maximum SFP (specific fan power) of 2.0 kW per m³/h (3.4 kW per cfm) air delivered. This figure becomes 1.5 kW per m³/h (2.55 kW per cfm) in 2009. • EnEV also stipulates annual energy inspections of air-conditioning systems with a refrigerating power of more than 12 kW. These inspections start with all components that affect the efficiency of the plant and include the dimensioning of the plant, checking the plant design, changes in the room use/occupancy, time used, internal heat sources, building physics, humidity, operating times and tolerances. These inspections apply to about 450,000 plants. • The German market for room air conditioners has doubled from about 65,000 outdoor units sold in February 2009 Market at a Glance http://www.ashrae.org
