The invention proposes a method for controlling a refrigeration cycle (12) having a compressor (13), a condenser (14), an expansion valve (15) and an evaporator (16), in which a refrigerant-oil mixture (10) flows. The method comprises the following steps: setting a target value range of an oil circulation rate OCR, determining the oil circulation rate OCR at a measurement point in the refrigeration cycle 12, checking whether the measured oil circulation rate OCR is within a target value range of the oil circulation rate OCR and changing the oil circulation rate OCR when the measured oil circulation rate OCR is not within the target value range of the oil circulation rate OCR. The invention further relates to a refrigeration cycle 12, to a thermal management system 29 and to a vehicle 21.

    本发明提出一种控制制冷循环12的方法,所述制冷循环具有压缩机13、冷凝器14、膨胀阀15和蒸发器16,其中制冷剂‑油混合物10在所述制冷循环12中流动。所述方法具有以下步骤:设定油循环率OCR的额定值范围,在所述制冷循环12中的测量点处测定所述油循环率OCR,检查所述所测得的油循环率OCR是否处于所述油循环率OCR的额定值范围内以及在所述所测得的油循环率OCR不在所述油循环率OCR的额定值范围内时,改变所述油循环率OCR。此外,本发明还提出一种制冷循环12、一种热管理系统29以及一种车辆21。
