The invention provides an air conditioner refrigerating system and an automobile. The system comprises a condenser, a compressor, a first expansion valve, a second expansion valve, two three-way joints and a heat exchanger. The air conditioner refrigerating system is connected through an air conditioner pipeline, and the air conditioner pipeline comprises an air suction pipe, an exhaust pipe and ahigh-pressure pipe; one three-way joint is connected with the first expansion valve, the second expansion valve and the condenser, the other three-way joint is connected with the first expansion valve, the second expansion valve and the compressor, and the compressor is connected with the condenser through the exhaust pipe so that the air conditioner refrigerating system forms two refrigerating circuits; one refrigerating loop comprises the compressor, the condenser, the three-way joint, the first expansion valve and the three-way joint which are connected in sequence; and the other refrigerating loop comprises the compressor, the condenser, the three-way joint, the second expansion valve and the three-way joint, the second expansion valve is further connected with the heat exchanger, andthe heat exchanger is connected with the water cooling pipeline. The battery pack can be cooled, the use condition is optimized, and the service life is prolonged.
