description The invention belongs to the technical field of aerospace thermal control, and particularly relates to an environment cooling system and method based on phase-change heat exchange. The system is characterized in that the dual-channel phase change heat exchanger is provided with a first heat exchange channel and a second heat exchange channel, an outlet of the first heat exchange channel is provided with a first nozzle, and an outlet of the second heat exchange channel is provided with a second nozzle; the liquid nitrogen storage tank is connected with an inlet of the first heat exchange channel through a first pipeline, and a liquid nitrogen control valve is arranged on the first pipeline. The air circulating pump is connected with an inlet of the second heat exchange channel through a second pipeline; the number of the temperature sensors is at least two, one temperature sensor is arranged in the double-channel phase change heat exchanger, and the other temperature sensor is arranged in the equipment cabin.
