摘要
本文通过对风冷热泵冷热水机组结霜因素的分析,提出了多参量自调整模糊除霜控制的方法,建立了自调整模糊控制除霜系统的总体结构;在实验的基础上,确定了各输入参数的隶属函数,采用SIEMENSS7-200可编程控制器,设计开发了风冷热泵冷热水机组的自调整模糊除霜控制系统。实验运行表明:本文的研究有效的提高了风冷热泵冷热水机组冬季运行的制热性能,节能效果好。
After the analysis of the air-cooled heat pump /chiller,the method of multi-parameter self-adjusting fuzzy control to defrosting is showed and the architecture of system is also established.On the base of experi-ments,the membership functions of the input parameters are defined.This fuzzy control system is developed by SIEMENS S7-200prog rammable controller.After a period of running ,it proved that this system is reliable,efficiently and lower energy consuming .
