Performance Analysis of a Wet Air-Cycle Refrigeration System

Performance Evaluation of Small Centrifugal Compressors for Application in Air-Cycle Power and Refrigeration System

Application of Pinch Analysis in an Air-Conditioning Refrigeration System

A new method pinch analysis is introduced to discuss design optimization of the air-conditioning refrigeration system from the point of view of saving energy and saving material, and the evaluation principle of system economy is built up. The method avoids the defect of traditional design method using experience, easy to realize optimum match between system component parts. c Cp COP F G H M p P...

A Transcritical Refrigeration Cycle with Carbon Dioxide for Bus Air Conditioning and Transport Refrigeration

The frrst part of this paper presents carbon dioxide air conditioning units which were installed in two city buses. The two buses were tested "on-the-road" during summer 1997 in Bad Hersfeld, Germany. By the end of 1997, the air condition systems of the two buses had been running together for more than 860 hours proving that C02 systems fulfill important on-the-road requirements. In the second ...

Development of Air Cycle Technology for Transport Refrigeration

Developments for air cycle systems with respect to special requirements concerning the use of compression and expansion machines for transport refrigeration are discussed in this paper. Historic aspects are mentioned briefly and the present situation in Germany is sketched in the example of an air cycle air-conditioning system for the new generation of the German high speed train ICE 2.2. In or...

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...
