Design and Analysis of Combined-cycle Indirect Air Cooling System in Combined Cycle Units

In this paper, we discusses the pattern of development and prospects of combined cycle. On the the importance of gas-steam combined cycle system using indirect air-cooling technique. on the basis of introducing the power plant air-cooled system, Analysis the advantages and disadvantages of a variety of air-cooling technology used in practical production.By combined cycle using Refrigeration Cycle Indirect Air Cooling System, discuss the process of designing. Analysis the factors of the compressor - Air-cooled radiators, and changes of the properties have been studied. The results show that the design process of refrigeration Cycle must considered weather conditions, and ambient wind speed, refrigerating capacity, heat exchanging area, layoutof air cooling power station for Special.
