The invention discloses an ammonia dual-fuel ship food refrigeration system and method and a ship. The system comprises a refrigeration water circulation system, a liquid ammonia cold energy recovery heat exchange system and a refrigerant water heat exchange system. The refrigeration water circulation system, the liquid ammonia cold energy recovery heat exchange system and the refrigerant water heat exchange system are communicated through pipelines. Wherein the refrigeration water circulation system and the liquid ammonia cold energy recovery heat exchange system are arranged in the ammonia fuel supply system equipment room and are communicated with each other through a refrigerant water main pipeline. And the refrigerant water heat exchange system is arranged in the food refrigeration buffer room. And the refrigerant water main pipeline extends out of the ammonia fuel supply system equipment room and is communicated with the refrigerant water heat exchange system in the food refrigeration buffer room through a pipeline. And a state monitoring and pipeline opening and closing device is arranged on a pipeline for connecting each system with the unit and is used for controlling the starting and operation of the refrigerating system.
