The invention relates to the technical field of cold chain equipment, and provides a refrigerating system, a control method of the refrigerating system and cold chain equipment. The refrigerating system comprises a compressor, a condenser, a throttling element, an evaporator and a standby power compressor, a first pipeline is communicated between an outlet of the compressor and an inlet of the condenser, a second pipeline is communicated between an outlet of the condenser and an inlet of the throttling element, and a third pipeline is communicated between an outlet of the throttling element and an inlet of the evaporator. A fourth pipeline is communicated between an outlet of the evaporator and an inlet of the compressor; an inlet of the standby power compressor is communicated with an inlet of the compressor, an outlet of the standby power compressor is communicated with an outlet of the compressor, the outlet of the compressor is provided with a first check valve, and an outlet of the standby power compressor is provided with a second check valve. According to the technical scheme, the standby power compressor can be used for cooling in the parking state, oil consumption can be reduced, and the problems of oil return and blow-by of the standby power compressor and the vehicle-mounted compressor can be avoided.

    本申请涉及冷链设备技术领域,提供一种制冷系统、制冷系统的控制方法及冷链设备。其中,制冷系统包括压缩机、冷凝器、节流件、蒸发器和备电压缩机,压缩机的出口与冷凝器的进口之间连通有第一管路,冷凝器的出口与节流件的进口之间连通有第二管路,节流件的出口与蒸发器的进口之间连通有第三管路,蒸发器的出口与压缩机的进口之间连通有第四管路;备电压缩机的进口与压缩机的进口连通,备点压缩机的出口与压缩机的出口连通,且压缩机的出口设有第一止回阀,备电压缩机的出口设有第二止回阀。通过本申请的技术方案,能够在驻车状态下使用备电压缩机进行降温,不仅可降低油耗,且可避免备电压缩机和车载压缩机出现回油和串气的问题。
