The invention discloses an ammonia dual-fuel ship air conditioner refrigerating system and method and a ship. The system comprises an air conditioner water chilling unit system, a liquid ammonia cold energy recovery heat exchanger system, an air conditioner refrigerant water expansion tank and an air conditioner. The air conditioner water chilling unit system, the liquid ammonia cold energy recovery heat exchange system, the air conditioner refrigerant water expansion tank and the air conditioner are connected with corresponding valves through circulating pipelines. Wherein the air conditioner water chilling unit system and the liquid ammonia cold energy recovery heat exchanger system are arranged in the ammonia fuel supply equipment room, and the air conditioner refrigerant water expansion tank and the air conditioner are arranged in the cab. And an air conditioner refrigerant water circulating pump is arranged on the circulating pipeline in the ammonia fuel supply equipment room. By recycling the cold energy of the ammonia fuel stored at low temperature, the problem that the ship is difficult to maintain and replace the refrigerant in the European Union area is solved, the electric energy of the dual-fuel ship is saved, and the effects of energy conservation and emission reduction are achieved.
