Energy and exergy analysis of an Automobile Heat Pump system
This study deals with energy and exergy analysis of an Automobile Heat Pump (AHP) system using R134a as the working fluid and ambient air as a heat source. An experimental AHP system consisting of original components from an Automobile Air Conditioning (AAC) system and some extra equipment was developed and instrumented. The system was operated in steady state under various ambient and return air ...

Coordination of exergy analysis and the MIND method - applied to a pulp and board mill
The MIND (Method for analysis of INDustrial energy systems) method has been developed for cost optimisation of industrial energy systems, mainly with regard to quantities of energy. Exergy analysis reveals losses, efficiencies and possible improvements. These methods can be combined in order to improve industrial energy systems. In this paper, a Swedish pulp and board mill is used as a case ...

Energy analysis in industrial districts: a statistics-based approach
Considering the particular structure of the Italian productive system, characterised by local concentration of a great number of small and medium-sized enterprises in industrial districts, this study aims at developing a "district-oriented" approach to energy analysis. A combination of statistical methods is proposed in order to describe similarities, variability and relations among different ...

The model based on the analytic hierarchy process for dynamic decision making in the energy industry: a case analysis of investment energy production in Finland
The goal of the research was to find out, define and evaluate the major factors of the decision-making process in the energy industry, especially in Finland. The theoretical part of the current research consists of energy system models and Analytic Hierarchy Process (AHP) model theories. The additional objective was to determine the characteristics of the Finnish energy industry. The research ...

Cumulative exergetic assessment of LPFO utilised steam boilers
This paper relates to a study on the energy and exergy resources, transfers, consumption and losses in the combustion and heat exchanging units of industrial steam boilers. Mass, energy and exergy analyses, which included the physical and chemical exergies of material streams, were used to investigate the energy resource utilisation of Low Pour Fuel Oil (LPFO) in industrial steam boilers. The ...

Energy Efficiency, Pollution Prevention, and the Bottom Line
Introduction For many years, efforts to promote energy efficiency and pollution prevention (P2) traveled on parallel paths. Most energy efficiency advocates considered only the energy savings aspects of their projects and most proponents of P2 did not include energy on their list of sources of pollution. More recently, the two groups promoting energy efficiency and P2 have begun to realize the ...
