Compared to a photovoltaic array, a photovoltaic/thermal concentrator module can produce thermal power for various productions in downstream cycles in addition to electrical energy. In this study, the system for the combined production of electricity, heat and cooling based on a photovoltaic/thermal concentrator has been evaluated. In this triple production system, a lithium bromide-water absorption chiller with a cooling capacity of 5 kW was used. In the organic Rankine power generation cycle, the annual exergy rate of the incoming stream was almost 48 MWh, the annual production exergy rate was about 54.4 MWh and the annual exergy destruction rate was ~43.1 MWh. According to the results, the freshwater production rate of the desalination plant was approximately 56.7 m³/year; the lowest month was 3.8 m³ in November.

The system presented in this paper can change the energy storage landscape by having the advantages of a compressed air storage system and pump storage, as well as minimizing the disadvantages of these two systems. One of the advantages of this system compared to similar systems is the lack of combustion of natural gas. Correspondingly, for construction, it does not require specific specifications for the executive site, and control of the energy and heat of the system (due to the use of water as an operational fluid) is easier than similar systems. In addition, this system is very scalable and can be designed in low capacities to high capacities, energy analysis of this research to identify the basic and effective parameters of the system and determine the limitations and relationships between them. The amount of energy saved in the current research system compared to previous research is significant, and 92% efficiency can be achieved. The energy analysis of this research determined the effect of the parameters on each other and their limitations so that the path of its feasibility design was paved.

Today, using systems based on renewable resources is a suitable alternative to fossil fuels. However, due to problems such as the lack of access in all the times needed to supply cargo and high-investment cost, it has not been well-received. Therefore, in this research, the modeling of the photovoltaic system with battery storage has been done to supply the required load, and various scenarios have been evaluated in terms of economic parameters and reliability indicators of the studied system for a better understanding of the comparison indicators. It has been evaluated from two modes, one connected to the network and one disconnected from the network. One of the important results is the supply of 56% of the load by the photovoltaic cell in the presence of the grid, which, in this scenario, the electrical load is supplied by the photovoltaic cell and the grid is 164.155 kWh/yr and 128.504 kWh/yr, respectively.

This paper aims to study and evaluate the corrosion resistance of Ni₅₅Nb₄₅ and Ni₅₅Nb₃₅Co₅Zr₅ bulk metallic glasses (BMGs) in an environment similar to proton exchange membrane fuel cells. Moreover, the hot compression process was carried out to find the effects of a thermomechanical treatment on the corrosion resistance. The X-ray diffraction (XRD) test indicated that the hot compression process led to formation of crystalline species in both samples; however, it was more pronounced in the Ni₅₅Nb₃₅Co₅Zr₅ alloy. It is suggested that the minor addition of Zr and Co facilitated the crystallization in the material. The polarization test unveiled that the hot compression deteriorated the corrosion resistance of the Ni₅₅Nb₄₅ alloy through the introduction of anomalous chemical interfaces. On the other hand, the hot deformation affected the Ni₅₅Nb₃₅Co₅Zr₅ alloy in a positive way, so that the corrosion behavior improved compared with its fully glassy state. It is suggested that the hot deformation induces some NiNb crystalline constituencies in the microstructure of Ni₅₅Nb₃₅Co₅Zr₅ BMG, leading to the enrichment of glassy matrix from Zr/Co constituencies and the enhancement of corrosion resistance.
