摘要:

通过线性压缩机的实验研究和理论分析,研究了电冰箱用线性压缩机控制系统中行程检测、上死点检测和变工况性能优化这几个关键控制技术。在此基础上,根据电冰箱用线性压缩机的控制目标,制定了适合电冰箱制冷运行的控制策略,并进行了制冷性能实验。与线性压缩机的联合运行制冷实验结果显示,基于上述控制技术的控制系统可以有效地实现线性压缩机高效可靠的制冷运行,实现电冰箱额定工况下制冷性能系数COP在1.74以上。

Abstract:

Three main key control technologies of linear compressor—stroke detection, top dead center (TDC) detection and performance improvement are investigated by the experimental research theoretical analysis. Based on the above control technologies, a control strategy of linear compressor for refrigerator is designed according to the control target of linear compressor for refrigerator. The coupling cooling operation results show that the control strategy can fulfill the control target well and the cooling COP of the linear compressor under the rating working condition of refrigerator is around 1.74.

Key words: linear compressor, control, kinetic, stroke detection, TDC
