Abstract

The present aims to simulate the energy consumption in the systems of air conditioning, for the purpose of determining the optimal system which features consume less energy and meets the requirements of the thermal condition. Hence, the design of a computer program language (Visual Basic 5) to determine the energy expended by the air – conditioning equipment for three different systems and at different periods of time. This program is designed according to the American Society of Heating, refrigeration, air conditioning Engineering and also depending on the data manufacturers of air conditioning equipment.
Program was used on a building located in the city of Baghdad has been designed three different system.
The research reached the energy consumed in the refrigeration compressor main factor in determining the optimal system and the others equipment does not constitute a small percentage, hitting 15% in intensive water – cooled and 8% in intensive air – cooled systems. And the different between the actual consumption and simulation value it is not moor 7%
