The invention provides a heat exchange system and refrigeration equipment, and the heat exchange system comprises a compressor; the first heat exchanger is connected with the compressor; the supercooling pipe is connected with the first heat exchanger; the throttling valve is connected with the supercooling pipe, and the conduction state of the throttling valve comprises a throttling state and a non-throttling state; the second heat exchanger is connected with the throttle valve; the air return pipe is connected with the second heat exchanger and the compressor. According to the heat exchange system provided by the invention, the throttling valve has two conduction states, and under the condition that the conduction state of the throttling valve is the throttling state, the heat exchange system can perform normal heat exchange work. The heat exchange system can be vacuumized under the condition that the throttling valve is in the non-throttling state in the conducting state, and due to the fact that the throt
