The Influence of Air-Conditioning Operating Schedule and Ventilation needs on Energy Consumption

This paper analyses the influence of air-conditioning operating schedule and ventilation needs on the daily energy consumption. Analysis has been made on the basis of a computer program for dynamic simulation of air-conditioned rooms thermal behavior. The program has been developed at the Department for Thermal Engineering at the Faculty of Mechanical Engineering, University of Belgrade. Analysed are three different air-conditioning operating schedules and three different flow rates of fresh air in the system. Given are cooling loads, energy needed for outdoor air treatment, fan energy consumption and overall daily energy consumption for summer design conditions for Belgrade. The obtained results have been compared, and hereupon given a review of the daily energy savings.
