摘　　要：将结霜的主要影响因素和热泵系统对结霜状况的响应这两个方面确定为机组开始除霜的输入判据。在此基础上,研究模糊除霜的控制算法,确定隶属函数与模糊集,建立模糊规则表,并且确定除霜指令和除霜效果的评判,为实现空气源热泵热水机组的实时除霜控制和提高机组的运行性能奠定基础。Points out the main factors of frosting and the response of heat pump to frosting as input criterion of the beginning of defrosting. Based on this, investigates the control algorithm of fuzzy defrosting, ascertains membership function and fuzzy sets, establishes table fuzzy rules, and ascertains defrosting instructions and the evaluation of defrosting results, which lays a foundation to realize the real-time defrosting control of air source heat pump unit and improve the performance of unit.
