Mathematical Modelling of a Hydraulic Accumulator for Hydraulic Hybrid Drives

Saving Energy by Exergetic Analysis of MTP Process Refrigeration System

The exergetic analysis is a tool that has been used successfully in many studies aiming a more rational energy consumption to reduce the cost of processes. With this analysis, it is possible to perform an evaluation of the overall process, locating and quantifying the degradation of exergy. This paper applies exergy approach for analyzing the heat exchanger network design and refrigeration of M...
