德国LTG空调的变频器控制改造

TRANSFORMATION OF FREQUENCY CONVERTER OF LTG AIR CONDITIONING MADE IN GERMANY

介绍一种对德国LTG空调采用变频控制进行改造的方法,前纺环境风采用开环控制,侧吹风采用闭环控制,大大降低了整个空调系统的能耗,提高了侧吹风风压的稳定性。

A transformation method is introduced,which frequency control is adopted in the LTG air conditioning.During the transformation,the opened loop control is used in the enviroment air conditioning of POY section,and then the losed loop control is used in the quench air system.This method can decrease the energy consumption greatly and increase the pressure stabitity of the quench air.
