Environmental Analysis of High Temperature Solar Heat Pump, Case Study of Hot Water Production System With Weather Conditions of Ahvaz

Abstract

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 10. 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 K100 compressor with 87.63%. Also, the lowest exergy destruction rate of the rotating components is related to the pump P100 with 0.52 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 K101 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.
