Solar Thermal System

The purpose of this paper is to describe the implementation of a laboratory-scale solar thermal system for the Renewable Energy Systems Laboratory at the Milwaukee School of Engineering (MSOE). The system development began as a student senior design project where students designed and fabricated a laboratory-scale solar thermal system to complement an existing commercial solar energy system on campus. The solar thermal system is designed specifically for educating engineers. This laboratory equipment, including a solar light simulator, allows for variation of operating parameters to investigate their impact on system performance. The equipment will be utilized in two courses: Applied Thermodynamics, and Renewable Energy Utilization. During the solar thermal laboratories performed in these courses, students conduct experiments based on the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) 93-2010 standard for testing and performance characterization of solar thermal systems. Their measurements are then used to quantify energy output, efficiency and losses of the system and subsystem components.

And Performance

The main priority in photovoltaic (PV) panels is the production of electricity. The transformation of solar energy into electricity depends on the operating temperature in such a way that the performance increases with the decreasing temperatures. In the existing literature, different cooling techniques can be found. The purpose of most of them is to use air or water as thermal energy carriers. This work is focused on the use of air as a working fluid whose movement is either induced by natural convection or forced by means of a fan. The aim of this study is to characterise the electrical behaviour of the solar panels in order to improve the design of photovoltaic installations placed in roof applications ensuring low operating temperatures which will correct and reverse the effects produced on efficiency by high temperature. To do this, a test installation has been constructed at the Universidad Politécnica de Cartagena in Spain. In this paper, the results of the tests carried out on two identical solar panels are included. One of them has been modified and mounted on different channels through which air flows. The different studies conducted show the effects of the air channel cross-section, the air velocity, and the panel temperature on the electrical parameters of the solar panels, such as the voltage, current, power, and performance. The results conclude that the air space between the photovoltaic panels and a steel roof must be high enough to allow the panel to be cooled and consequently to achieve higher efficiency.

The Impact

This paper presents an investigation of map width enhancement and the performance improvement of a turbocharger compressor using a series of static vanes in the annular cavity of a classical bleed slot system. The investigation has been carried out using both experimental and numerical analysis. The compressor stage used for this study is from a turbocharger unit used in heavy duty diesel engines of approximately 300 kW. Two types of vanes were designed and added to the annular cavity of the baseline classical bleed slot system. The purpose of the annular cavity vane technique is to remove some of the swirl that can be carried through the bleed slot system, which would influence the pressure ratio. In addition to this, the series of cavity vanes provides a better guidance to the slot recirculating flow before it mixes with the impeller main inlet flow. Better guidance of the flow improves the mixing at the inducer inlet in the circumferential direction. As a consequence, the stability of the compressor is improved at lower flow rates and a wider map can be achieved. The impact of two cavity vane designs on the map width and performance of the compressor was highlighted through a detailed analysis of the impeller flow field. The numerical and experimental study revealed that an effective vane design can improve the map width and pressure ratio characteristic without an efficiency penalty compared to the classical bleed slot system without vanes. The comparison study between the cavity vane and noncavity vane configurations presented in this paper showed that the map width was improved by 14.3% due to a significant reduction in surge flow and the peak pressure ratio was improved by 2.25% with the addition of a series of cavity vanes in the annular cavity of the bleed slot system.

As the development trend of solar energy, which is a green way of energy utilization, photovoltaic power generation has been a research hotspot of solar energy utilization technologies. Using the concentrating and tracking technology to increase the illumination intensity, and obtain more electrical energy, that will reduce the cost of the photovoltaic power generation system sharply. A kind of steric and multilevel concentrator for photovoltaic generation is introduced in this paper, whose concentration ratio is 3. The operating factor of plane mirrors and performance price ratio of the system is increased for optimizing the condensation parameters and structure of the concentrator.

The Queen’s Residence Energy Challenge (QREC) is an energy conservation initiative taking place in the residence halls at Queen’s University coordinated by the AMS Sustainability Office and the Sustainability Coordinator for Student Affairs . It is a two-part competition. Part one of the competition is an interresidence competition in which each residence hall will be competing to reduce their energy expenditures. Energy use will be compared to the corresponding time in the previous year, and the residence that reduces their energy use by the highest percentage will win the competition. This part of the project is being organized by members of the AMS Sustainability Office and the Sustainability Coordinator (Office of Student Affairs), and Residence Life staff and floor dons are helping execute it. The second part of the competition is an inter-university pledge drive, in which residents will be encouraged to sign a pledge stating that they will be participating in the QREC. Queen’s will be competing against the Universities of Waterloo and Guelph, and the school that has the highest percentage of residents participating will win a set of solar panels as a symbol of energy conservation and renewable energy. This part of the project is being coordinated by the Sierra Youth Coalition who has obtained funding from the Ontario Power Authority. The goals of the QREC are to reduce overall energy use in the residences, help students living in residence learn about their own energy consumption and ways to reduce it, and create a culture of sustainability at Queen’s. In this presentation I will go through the overall timeline of executing and planning the project, provide examples of ways to reduce energy consumption in residence, and provide results of both parts of the competition.
