Room air conditioners: determination of empirical corelations for predicting building energy consumption

Two room air conditioners were modeled in order to predict the total cooling capacity, the sensible cooling capacity and the Energy Efficiency Ratio (E.E.R.) of each appliance. The mathematical correlations obtained were written in terms of room air wet bulb temperature and outdoor-side dry bulb temperature. The use of these correlations allows predicting building energy consumption, electric power demand and equipment performance characteristics  for  a wide range of outdoor-side dry-bulb and room-side wet-bulb temperatures. The experimental data, from which the correlations were created, were obtained in calorimeters according to standard ISO 5151 (1994). The uncertainty on measurements is also presented.
