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.
