Summary

In order to improve the modelling of air conditioners in building simulation tools, the characteristic curves for cooling capacity, sensible-cooling capacity and Energy Efficiency Ratio (EER) of two room units were determined. They were obtained by means of standard capacity tests on climatic chambers in a set of environmental conditions described by internal dry and external wet bulb temperatures. Afterwards, the performance of these two units and the four others, with and without taking into to account the thermodynamic variations of the surrounding environments on it, were compared using a whole building simulation program for simulating a conditioned space. The comparative analysis showed that the air conditioner with the higher energy efficiency rating not always provides the lowest power consumption in real conditions of use.
