The invention discloses a fault judgment method, the fault judgment method is used for judging the fault of a throttle valve in a refrigerating system, the refrigerating system comprises a compressor, a condenser and the throttle valve, and the compressor, the condenser and the throttle valve are sequentially arranged in a circulation loop of the refrigerating system. The fault judgment method comprises the steps that the outlet temperature of the condenser is obtained; obtaining the intermediate temperature of the condenser; the inlet temperature of the throttling valve is obtained; the temperature of an air inlet of the condenser is obtained; the outlet temperature of the condenser is compared with at least one of the intermediate temperature of the condenser, the inlet temperature of the throttling valve and the air inlet temperature of the condenser, and a comparison result is obtained; judging that the throttle valve breaks down according to the condition that the comparison result meets a preset condition; the invention further provides a refrigerating system, cold chain equipment, equipment and a storage medium.
