Thermal Diagnosis of Ventilation and Cooling Systems in a Sports Hall—A Case Study

Air conditioning systems in buildings consume a significant part of the world’s energy, and yet there are cases wherein users not satisfied with quality thermal environment. Examples such special sports halls, which require different conditions within single zone. Thermal diagnostics for can be used to diagnose problems. The aim paper was analyse effectiveness ventilation cooling hall cubature 16,300 m3 check possibility managing hall’s demands via existing air system. Diagnostic measurements were performed, including situ flows from diffusers their temperatures, visualization supply flows, monthly registration indoor temperature at set temperatures exhaust air. Additionally, numerical analysis, using EnergyPlus simulations, demand performed regard varying uses hall. analysis based on measurement simulation showed that it is possible remove heat gains current available flow.
