Buildings, which are in fact ecosystems (living and inanimate organisms interacting together), are nowadays conceived and operated on the base of energy assessments underpinned by the first law of thermodynamics, and design strategies work towards energy conservation. Different approaches, based on the second law of thermodynamics, exist in research; they use the thermodynamic function called e...

Multistage membrane distillation (MD) systems can have significantly higher efficiencies than their single stage counterparts. However, multistage MD system design has received limited attention. In this paper, the performance of a multistage vacuum membrane distillation (MSVMD) which is thermodynamically similar to a multi-stage flash distillation (MSF) is evaluated for desalination, brine con...

In this article, the first and second law analysis of diesel engine based cogeneration system was performed. Fuel utilization efficiency, rate of power, and rate of process heat of the plant were determined and various efficiencies based on both energy and exergy methods and the performance assessment parameters are defined for both the system components and the entire cogeneration plant. The o...
