With the rapid depletion of fossils fuels, scope for renewable energy like solar energy is huge. The efficiency of photovoltaic cells to convert the solar energy into electricity drops with the rise in temperature due to increased resistance. Thus improving the efficiency by lowering the thermal resistance and allowing the cooling fluid (air/water) to flow through photovoltaic thermal (PVT) system is an attractive engineering problem. In the present study, performance analysis of single glazed solar PVT air collector on the basis of energy and exergy has been analyzed for the climatic conditions of Silchar, India for the month of May, 2017. An analytical model is developed to evaluate the hourly variation of PV cell temperature, cell efficiency, useful thermal heat gain, useful electrical heat gain, energy efficiency and exergy efficiency PVT system. Results depict that efficiency of PV cell decreases with the increase in temperature, and a maximum efficiency of 14.6% for the PV module is found. Out of total useful heat output, electrical heat output contributes 67% while the rest is thermal heat output. Further, magnitude of both the heat output is found to increase with the solar radiation and the maximum is observed at around 1230 hrs. Trend of both energy and exergy efficiency is similar except the magnitude. Maximum efficiency observed to be 69% and 16.5% for energy and exergy respectively.

Investigations on exergy resources are important from the point of energy sustainability. In the presented study an energy and exergy analysis of the operating biomass and natural gas boilers at the University of Idaho (UI) district energy plant is conducted. Exergy flows through the components of the steam cycle associated with the biomass boiler are quantified to identify major sources of exergy destruction in the district heating system. It is found that the biomass boiler has reduced energy and exergy efficiency compared to the natural gas boilers. Thermal efficiency varies from 76% to 85%, while exergy efficiency is significantly lower at 24% to 27% for all the boilers.  Exergy accounting reveals that the biomass boiler and furnace account for the greatest exergy destruction, at approximately 68% of the exergy provided by the fuel. Steam use on campus represents about 6% of exergy losses while the pressure reducer is responsible for 3.5%.

The thermal energy storage (TES) of an actual district energy (DE) system is analyzed thermodynamically, using energy and exergy approaches. With a case study, the results for the TES of the DE system are verified with previous studies. The actual case considered is the Friedrichshafen DE system in Germany. This system is solar assisted, uses natural gas as a backup, and is equipped with a TES. The TES stores the surplus solar energy until is needed by thermal energy users of the system. Using solar energy allows the DE system to use significantly less fossil fuel than would otherwise be the case. Seasonal TES, which normally requires significant thermal insulation to adequately reduce thermal losses, is used in the DE system. The use and role of thermal storage in a district energy system is assessed considering the Friedrichshafen DE system. The results show the significant influence of the return temperature of the circulating media (water) from the DE system thermal network. Furthermore, the financial impact of the TES is not limited to a reduction of the operational cost of the DE system but also to an increase in the initial costs for the DE system.

Absorption chillers present opportunities to utilize sustainable fuels in the production of chilled water. An assessment of the steam driven absorption chiller at the University of Idaho, was performed to quantify the current exergy destruction rates. Measurements of external processes and flows were used to create a mathematical model. Using engineering equation solver to analyze and identify the major sources of exergy destruction within the chiller. It was determined that the absorber, generator and condenser are the largest contribution to the exergy destruction at 30%, 31% and 28% of the respectively. The exergetic efficiency is found to be 16% with a Coefficient of performance (COP) of 0.65. Impacts of weak solution concentration of lithium bromide on the exergy destruction rates were evaluated using parametric studies. The studies reveled an optimum concentration that could be obtained by increasing the weak solution concentration from 56% to 58.8% a net decrease in 0.4% of the exergy destruction caused by the absorption chiller can be obtained. The 2.8% increase in lithium-bromide concentration decreases the exergy destruction primarily within the absorber with a decrease of 5.1%. This increase in concentration is shown to also decrease the maximum cooling capacity by 3% and increase the exergy destruction of the generator by 4.9%. The study also shows that the increase in concentration will change the internal temperatures by 3 to 7 °C. Conversely, reducing the weak solution concentration results is also shown to increase the exergetic destruction rates while also potentially increasing the cooling capacity.
