Description

Technical Field

[0001] The present application relates to the technical field of ship design, and in particular to a method, system, storage medium, and terminal for calculating the load of a ship cabin air-conditioning system. Background Art

[0002] In the field of ship design, the cabin is the core place for crew members to live and rest. The precise control of internal temperature and humidity is directly related to the crew's living comfort and physical and mental health, and plays a key role in ensuring the crew's work efficiency and quality of life during the ship's voyage.

[0003] At present, the calculation of the temperature and humidity control load of ship cabins involves many complex factors, including the internal and external environmental conditions of the cabin, the cabin surface size and volume, the heating and insulation conditions of the bulkhead, the heat dissipation conditions of the cabin equipment and the number of people. The load of ship cabin air conditioning equipment is closely related to the cabin temperature and humidity control load, the supply and return air volume and the type of air conditioning system.

[0004] Under traditional calculation methods, designers must first extract cabin structural information from the ship's construction model, then perform heat and moisture load calculations according to relevant standards. Finally, they must aggregate the calculation results for all cabins to determine the air conditioning equipment load. This approach has significant drawbacks. On the one hand, the process of obtaining cabin structural information is cumbersome and time-consuming. On the other hand, the heat and moisture loads must be calculated separately for each cabin, requiring frequent repetitive calculations. This is especially true for special ship types with thousands of cabins. Traditional calculation methods are labor-intensive and inefficient, making it difficult to meet the time constraints of ship design projects. Therefore, how to quickly and efficiently calculate cabin heat and moisture loads, as well as air conditioning equipment loads, has become a technical challenge that needs to be overcome in the field of ship design.
