Alternatives to ammonia/water absorption refrigeration cycles that have no need for purification include ammonia/LiNO3 and ammonia/NaSCN cycles. Similar to the other absorption refrigeration cycles they have low coefficients of performance and exergy efficiencies at low generator temperatures....

Recently, the TLC (trilateral power cycle) has attracted significant interest as it provides better matching between the temperature profiles in the evaporator compared to conventional power cycles. This article investigates the performance of this cycle and compares it with those for the ORC...

Significant benefits are shown to be possible in the province of Ontario by implementing utility-based cogeneration using the facilities of the main provincial electrical utility, Ontario Hydro. Six cogeneration scenarios are assessed, and show that cogeneration can provide significant...

Canadian energy utilization for 1986 is analysed by considering the flows of energy and exergy through the four main sectors of the economy (residential-commercial, industrial, transportation, and utility). Exergy analysis indicates a less efficient picture of Canadian energy utilization than...

The results are reported of comparisons based on energy and exergy analyses of a wide range of production processes for hydrogen and hydrogen-derived fuels (HDFs). A commercial process-simulation computer code, previously enhanced by the author for exergy analysis, is used in the analyses....

An advanced exergy analysis is reported for a recently developed configuration of an externally-fired combined-cycle power plant integrated with biomass gasification. The results identify the potential for improvement of the overall system considering interactions among the components. It is...

The role of increased energy efficiency in achieving sustainable development is investigated. Specifically, the relations are examined between energy (and energy efficiency) and sustainable development. Also, the linkages are discussed between energy efficiency and environmental impact, and the...
