Control method of refrigerating system, refrigerating system and refrigerator

The invention provides a control method of a refrigerating system, the refrigerating system and a refrigerator. The refrigerating system comprises a compressor and a refrigerating chip, and the control method comprises the steps that a refrigerating instruction is received, and a starting strategy is determined; and based on the starting strategy, the compressor and the refrigeration chip are controlled to be started, so that the starting time of the refrigeration chip is not earlier than the starting time of the compressor. According to the control method of the refrigerating system, the processing technology of the refrigerating system can be reduced, and the stability of the refrigerating system is improved.
