[0001] The present invention relates to the technical field of air conditioning control, and in particular to a ship air conditioning system and an intelligent control method thereof. Background Art

[0002] The ship air conditioning system is an essential basic facility in the ship. At present, the air conditioning systems of fishing boats, cargo ships, and passenger ships all use compression air conditioning units to provide heating or cooling for ship air conditioning needs. Compression air conditioning units generally use diesel generators to provide electricity, which consumes a lot of energy. However, the global energy is in short supply now, and the price of diesel is also rising. Because of this, the cost of using air conditioning on ships is also increasing to a certain extent. In addition, in the air conditioning and ventilation system of modern ship superstructures, the air supply terminal in the room often uses a blower. The existing model layout method is to arrange and connect the blowers, blower feet, flexible hoses, reducers, air ducts and other pipe accessories one by one, and then adjust them according to the ceiling and room layout. Finally, the air ducts of multiple rooms are connected to the main pipeline. Such design modeling takes a long time, the operation steps are cumbersome, and it is easy to cause omissions or interference. Summary of the invention
