International Congress and Exhibition on Air Conditioning, Heating and Cooling (Kgh) 2026
The International HVAC&R Congress and Exhibition — known as KGH (an acronym for heating, cooling and air conditioning in Serbian) — reaches its 57th edition in 2026. It is the longest-running annual gathering in Serbia for the heating, ventilation, air conditioning and refrigeration (HVAC&R) industry.
The 2026 edition takes place at Belgrade Fair, Hall 4, Belgrade, Serbia, from 9 to 11 December 2026. KGH uniquely combines a scientific congress with a trade exhibition, giving manufacturers, importers, distributors, engineers, designers, researchers and students a single meeting point.
The programme covers HVAC systems and equipment, refrigeration and refrigerants, nZEB buildings and decarbonisation, urban heat supply, renewable energy sources and applications, indoor air quality, and the growing role of artificial intelligence in smart HVAC and data-centre cooling.
Organised by the Serbian HVAC&R Society (within the Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia), the event typically brings together 160+ exhibitors and 3,000+ visitors, with free entrance on mandatory registration.
