The main purpose of this study is to evaluate the energy consumption quality of the hot water production system with weather conditions of Ahvaz. 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. 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. 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.

In high-exergy demand companies like piping companies, using renewable energies can be very useful in Manning the needed energy. Exergy analysis in thermal energy systems is very important, considering the need to determine the location and magnitude of the inefficiency of the system equipment. Utilizing annual meteorological data for Dezful, located in southwest Iran, this study considered the inefficiency of the solar water heating system. As an innovation, a complete analysis of the inefficiency of the equipment of the solar hot water production cycle was considered and the methods of reducing the inefficiency of the equipment were assessed. Energy consumption quality was calculated based on two parameters of exergy efficiency and exergy destruction using the coding capability of MATLAB software, after embedding the modeling in Aspen HYSYS software. While solar collector with 15701.8 kW and Pump1 with 0.51 kW had the highest and lowest exergy destruction, Heat Exchanger 2 with 99.99% and Pump1 with 75.51% had the highest and lowest exergy efficiency. Among the rotating equipment that consumes electricity, Compressor 2 had the most exgegy degradation with 223.1 kW. Also, the results of investigating the effect of ambient temperature showed that the solar collector had the highest and lowest exergy destruction in the month of JAN with 16125.7 kilowatts and in the month of July with 14927.6 kilowatts, and compressor 2 also had the highest exergy destruction in the month of Jan with 216.11 kilowatts and in the month of July with 235.76 kilowatts. and had the least exergy destruction.

In this paper, the thermodynamic performance of a solar assisted high temperature heat pump with water heating application is investigated. The comprehensive simulation and analysis of energy and exergy was done by Haysis and MATLAB software. This analyzes produce some convincing results due to the use of environmentally friendly and environmentally friendly energy sources. Thermodynamic analysis in thermal energy systems is very important due to the identification of high-consumption equipment and determining the location and level of inefficiency of the system equipment. According to the results of the system energy, among the equipment of the P100 pump system and the HX1 heat exchanger, it has the lowest and the highest energy consumption, respectively. 2.09 and 22669.11 kW. Also, the exergy analysis shows that the highest amount of exergy of currents with 367092 kW is related to the input flow of the tank and the highest exergy destruction of the equipment is 15563 kW related to the solar collector. This exergy destruction of the solar collector with temperature changes throughout the year with the lowest destruction in July at the rate of 14342 kW and the highest exergy destruction of 15678 kW relates to the month of June. Among the rotating equipment, the most exergy destruction is related to the k101 compressor of the water heat transfer cycle.

One of the most important steps in using any renewable energy source is to accurately estimate it. Universal solar radiation is generally measured on a horizontal surface, while the maximum amount of solar radiation is a collision on a sloping surface. However, in order to take full advantage of solar radiation on collector surfaces, conventional fixed solar systems, both solar photovoltaic and flat panel solar collectors, are installed on sloping surfaces. In this study, the HDKR model has been used to estimate the radiant energy on the horizontal and sloping surfaces of solar collectors. In this regard, using MATLAB software, the amount of energy received by the solar collector throughout the year was investigated. The results of this study show that in the Ahvaz International Airport station, in terms of average monthly, the highest amount of direct radiation for clear skies is related to June with 206 kWh / m2 and the lowest amount of radiation for February is 113 kWh / m2. Square meters.
