The invention relates to a method (100) for operating a heat pump (10) of a motor vehicle, comprising a compressor (11), an expansion means (13), an ambient heat exchanger (14) and a heating-heat exchanger (12). The method (100) comprises initiating (101) a defrosting operation for defrosting the ambient heat exchanger (14), where the defrosting operation comprises the steps of compressing (102) the refrigerant to a high pressure by means of the compressor (11), transferring (103) thermal energy to the ambient heat exchanger (14), decompressing (104) the refrigerant to a low pressure by means of the expansion means (13), and absorbing (105) thermal energy. The method (100) is characterized in that a defrosting process of the ambient heat exchanger (14) triggered by the defrosting operation is monitored (106), the monitoring (106) of the defrosting process comprises monitoring (107) of a pressure difference between a high pressure and a low pressure and/or monitoring (108) of a pressure difference gradient of the pressure difference between the high pressure and the low pressure and/or monitoring (109) of the high pressure.

    本发明涉及一种用于运行机动车的热泵(10)的方法(100),该热泵包括压缩机(11)、膨胀器件(13)、环境热交换器(14)和加热‑热交换器(12)。该方法(100)包括启动(101)用于对环境热交换器(14)除霜的除霜运行,其中,该除霜运行包括以下步骤:借助于压缩机(11)将制冷剂压缩(102)到高压,将热能传递(103)到环境热交换器(14)上,借助于膨胀器件(13)将制冷剂减压(104)到低压和吸收(105)热能。所述方法(100)的特征在于,监测(106)由除霜运行触发的环境热交换器(14)的除霜过程,其中,对除霜过程的监测(106)包括对高压和低压之间的压差的监测(107)和/或对高压和低压之间的压差的压差梯度的监测(108)和/或对高压的监测(109)。
