Computer simulation for better air-conditioning and ventilation design of industrial halls

The paper deals with the use of computer simulations both for the design support of HVAC systems development in existing industrial buildings. There is presented selected industrial hall and its HVAC systems concept. The computer simulation using ESP-r software for different rates of ventilation by outdoor air helped to design an air-conditioning system, which comprises of daytime top cooling and night ventilation by outdoor air combined with accumulation of cold in building constructions. Capacity of mechanical cooling was decreased to more that 50% comparing to original design based on manual calculation for peak loads. The importance of internal gains measurements and investigation for industrial halls is presented as well
