Background: The main purpose of this study is to evaluate the energy consumption quality of the hot water production system with weather conditions of Ahvaz.Methods: The related simulation is carried out using Aspen HYSYS software, version ۱۰. Then Aspen HYSYS and Matlab software were used for exergy and environmental exergy and environmental exergy analyzes.Results: According to the study results, the exergy analysis showed that the highest exergy efficiency of the rotating components is related to the K۱۰۰ compressor with ۸۷.۶۳%. Also, the lowest exergy destruction rate of the rotating components is related to the pump P۱۰۰ with ۰.۵۲ kW. Also, an analysis of the effects of equipment on the environment from the perspective of life cycle assessment (LCA) and the effect of exergy destruction on the environment was conducted on the equipment so that the fb solar collector had the highest value among other equipment, indicating the greatest environmental effect of the inefficiency of this equipment. Compressor K۱۰۱ should also be reviewed for LCA due to the high percentage of environmental factors.Conclusion: The results show that the environmental exergy analysis of the hot water production system can identify inefficient equipments and their impact rate on the environment.
