Ship efficient cooling and power cogeneration and control system coupled with S-CO2 Brayton cycle

The invention discloses an S-CO2 Brayton cycle coupled ship efficient cooling and power co-production and control system. The system comprises an S-CO2 Brayton cycle, an ammonia water absorption type refrigeration cycle and a multi-working-condition cycle monitoring and control system. According to the efficient cooling and power co-production and control system, the refrigeration requirement of a nuclear power ship under the ice temperature storage and air conditioner refrigeration working conditions can be met, and the circulation total volume and cost can be reduced; physical property parameters of S-CO2 at an inlet of the Brayton cycle compressor can be monitored through the cycle performance parameter monitoring feedback control system so as to guarantee operation safety, cycle parameters and parts in ammonia water absorption type refrigeration cycle can be monitored and controlled according to different refrigeration requirements, and the good low-temperature heat source recycling capacity and the good
