37th International Congress on Heating, Refrigerating and Air-Conditioning (2006) The 37th Congress on Heating, Refrigerating and Air-Conditioning, organized by SMEITS – the Serbian Society for Heating, Refrigerating and Air-Conditioning, was held in the Save Centre, Belgrade, from 6th to 8th December 2006, with about 600 participants and numerous guests and lecturers from Asia, America and 15 European countries. Within the Congress, a very successful exhibition of equipment and accomplishments was held with over 140 exhibition stands. The Congress opening The Congress was formally opened by Dr Tibor Sabor, the Assistant Minister for Basic Research of the Ministry of Science and Environment Protection, and the audience was addressed by professor Bratislav Blagojevic, PhD, director of “Feniks BB“ company, the general patron of this congress. They were both presented by the Chairman of the Congress Organizing Committee, prof. Branislav Todorovic, PhD, who first greeted the congress participants. Introductory lectures The professional programme of the Congress included three introductory lectures of the authors from England (Derek Clements Croome, Professor from Reading University), Slovenia (Professor Peter Novak, PhD) and Singapore (Chandra Sekhar, Professor from the Singapore National University). Energy Efficiency Section The introductory speech and report in the First Section were given by Dr Kostas Balaras of Greece, who spoke about energy evaluation of nonresidential buildings, and Zoltan Madjar of Hungary spoke on the European view of the energy performance of buildings. Other lecturers spoke on energy management (S. Maksimovic and S. Todorovic) and methods testing and program support for nonresidential buildings in terms of the EU Energy Performance of Buildings Directive (Marija Todorovic). Heat Generation and Cogeneration Section The Section dedicated to heat generation and co-generation included 8 lectures. The use of heating oil and its efficient combustion was the topic presented by colleagues from the company”Innospec“ from Great Britain, and representatives of the company “Ovex“ from Belgrade (B. Sretenovic and Dj. Kojic) made comments on the latest standards for feed and boiler water quality. The Faculty of Technical Sciences had its representatives (J. Petrovic and B. Gvozdenac) who presented the computer model for engineering and economic feasibility of co-generation distribution plants. The author from “Minel Kotlogradnja“ (B. Gacesa) talked about the new flue boiler’s geometry, and a group from the company “Bikozin“ and the Belgrade Faculty of Mechanical Engineering presented their experience and results regarding the use of additives in the public utility company „Beogradske elektrane“ (Belgrade Power Plants). Refrigeration Engineering Section A special section on refrigeration engineering was dedicated to the late professor Sava Vujic and it comprised 11 lectures. Presentation of sponsors The second day of the Congress began with the presentation of production lines of the general patron –«FENIKS BB» company of Nis, and main sponsors: «DANFOS», Belgrade, «DELTA TERM», Belgrade, «DOMING», Belgrade, «EL-TEC MULEJ», Nis, «ETAZ», Belgrade, «GROUP PROTEM», Belgrade, »HIDRIA IMP KLIMA«, Godovic, Slovenia, »IMI INTERNATIONAL«, Belgrade, »JUNKERS«, Belgrade, »PVF TRADERS«, Belgrade, »REFTECH«, Belgrade, »TECHNOLIY ITALIAN SERVICES«, Belgrade, »TERMONET«, Belgrade, »TROX TECHNIK«, Belgrade, and »YORK - JOHNSON CONTROLS«, Belgrade. Air Heating Systems Section There were several topics in the Section for air heating and ventilation systems. I. Mijatovic and M. Blagojevic from the Faculty of Occupational Safety of Nis discussed the central supervision and control systems, and the representatives of the Austrian company “Trox“ presented the flow regulator of air systems. Prof. Ozerdem from Turkey analyzed the heat transfer through an air-conditioning chamber, and the representative of the German company “Weiss Klimatechnik“ spoke about operating theatres in hospitals. S. Vlahovic presented a very efficient system for snow melting with panel system, and Vladan Petrovic from Kragujevac spoke about a new construction of panel radiators. District Heating Section Like always, many papers (10) were presented in the District Heating Section. Section of Solar Radiation Effects on Buildings and Solar Radiation Protection In this section, the following papers were presented: «On Precise Modelling of Self-Shading Façades » by J.Mardiljevic and K.Lomasa from the Institute of Energy and Sustainable Development of «De Monfort« University, UK, and «Preliminary Experiments with an Innovative Approach to Solar Radiation Control on Glazed Façades » by B. Natticci and A.Carbonari from Ancona, Italy. Section of Development of Sustainable Buildings and HVAC&R Systems The audience was specifically interested in the section for sustainable buildings, where 4 lectures were given. A guest from England, D. Braham spoke about the design on HVAC&R systems with heat accumulation in his country, and Professor Lee from Hong Kong spoke about the old method of floor heating which is still used in some Chinese villages. N. Miloradovic presented his paper on the past methods of heating with modern analyses of their effects talking about the Neolithic architecture and sustainable development. Daran Robinson was a guest from Switzerland, although he is English. He showed how heat and air flows are simulated in urban environment. Section of the application of CFD simulation in testing the indoor environment parameters This section was dedicated to simulation as a new tool in the design and evaluation of solutions, and 7 lectures were given. Section of Laboratories and HVAC&R Equipment Testing The last section on 7th December was on laboratories for testing HVAC&R elements and systems in Slovenia (E. Venko and P. Novak), and in Romania (a group of authors from the Technical University of Bucharest). Section of Renewable Energy Sources The last section was focused on renewable energy sources. Terry Townsend, ASHRAE President had two presentations on the future of HVAC&R profession, sustainable development and ASHRAE plans. Dr Lukic from Kragujevac presented his paper on flat solar receiver, and his colleagues from the same faculty, Bojic and Taranovic, presented the results of measurements on the hybrid solar energy receiver. Professor Marija Todorovic talked about the EU ACCENT project relating to the development of economical energy use of biomass in the countries of the West Balkans, and N. Djajic and D. Ivezic talked about possibilities, barriers and priorities in using renewable sources in the Balkans region. D. Mandaric and P. Varga from REHAU company gave a very interesting lecture on application of geoprobes in use of geothermal energy. The Congress work and materials All presentations at the Congress were simultaneously translated from Serbian into English and from English into Serbian, and the congress participants were very content with the translation quality. Banquette and award of recognitions The banquette was organized for the second day of the Congress. At the dinner, about 500 guests were greeted by the Chairman of the Organizing Committee, Dr Todorovic, and then recognitions were awarded to meritorious HVAC&R professionals.
