The presented review is focused on synergistic approaches, processes, design criterions and advances in working fluids to achieve optimum thermal and exergy efficiency for solar collectors mainly flat plate solar collectors, evacuated tube collectors and concentrating collectors.
How to analyze the production process of Solarus collectors?
In order to analyze the current production process of Solarus' collectors, a guideline is generated. With its help, it is possible to recognize key points in the assembly process that could be modified and would facilitate the mounting procedure or would reduce the overall production time.
Solar collectors with heat photovoltaic and thermal systems using heat pipes, and t hermoelectric generators ma de out of heat pipes. The first system type comprises a combination of sol ar panels with photovoltaics. This type is used the a bility to generate both heat and electrical energy concurrently .
Most of solar collectors are either designed for domestic applications, industrial process heating, for example milk pasteurization, pulp and paper industry, swimming pool heating and production of steam for process heating in spinning mils or to generate electric power using arrays of high concentrating cylindrical parabolic collectors.
What is a photovoltaic-thermal collector?
Photovoltaic-thermal collectors enable simultaneous electricity and heat generation within a single component. For technology development, we use our expertise in solar cells, module and collector technology as well as thermal and electrical measurement.
Do concentrating solar collectors improve thermal efficiency?
Concentrating solar collectors are most abundantly used for high temperature thermal applications. Design of receiver tube for surface modification to enhance high surface area for absorption were analyzed. Variety of inserts inside absorber tube were evaluated for their role in thermal efficiency enhancement in details.
Can a parabolic trough solar collector produce process heat?
In this paper are presented the results of designing a parabolic trough solar collector (PTSC), and its application in a solar thermal system for the production of process heat.
