A novel hybrid mutation operator was disigned to improve the quantization quality, and a stochastic sampling scheme was also presented for saving the run time. The experimental results demonstrate the superior performance of the proposed algorithm in comparison with the GA based algorithm.展开更多

The dynamic performance of the system has been investigated. The relationship between pressure, temperature and concentration of the lithium bromide solution have been analyzed. The result obtained indicates that the pressure of the high pressure generator and the temperature of the exhausted smoke are the most sensitive parameters. It is also found that the transition time from a full load to a part load condition is quite long, and part load relative cooling capacity is almost near the intermittent running time ratio and oil consumption ratio.展开更多
