A method comprising determining a first temperature of an oil inside a compressor (1); determining a second temperature at a moveable part (5) of the compressor (1), wherein the second temperature at the moveable part (5) is determined at a stationary part (4) of the compressor (1) being in contact with the moveable part (5); and deriving whether the compressor (1) operates in a safe mode or in an unsafe mode based on an analysis of the determined first temperature and the determined second temperature at the moveable part (5). 一种方法包括：确定压缩机(1)内的油的第一温度；确定压缩机(1)的可动部件(5)处的第二温度，其中，可动部件(5)处的第二温度在压缩机(1)的与可动部件(5)相接触的固定部件(4)处被确定；以及基于对确定出的第一温度和确定出的可动部件(5)处的第二温度的分析，推断压缩机(1)是以安全模式运行还是以非安全模式运行。
