摘要(Abstract):

分析了制冷压缩机吸气温度回路的特性 ,采用串级技术以量热器内第二制冷剂压力为副调参数组成串级系统 ,削弱了过程参数间的耦合影响 ,有效克服了二次干扰 ,实现了制冷压缩机吸气温度的快速稳定的控制
The performance of the inlet temperature are analyzed,the cascade control technology are adopted by regarding the pressure of the second refrigerator as the vice adjustment parameter.The control system not only weakens the couplings among the process parameters,but also quickly conquers the second disturbance.It can quickly and stably control the inlet temperature of the refrigerating compressor.
