摘要: 分析了邮轮舱室的传热机理与邮轮舱室负荷变化，根据进入室内和排出室外的热量来源和原理及能量守恒定律得出相应的传递函数。利用Simulink软件建立了舱室室温响应模型，探究了改变航速、航向对于内、外区客舱室温的影响作用，并根据实际邮轮的尺寸、设备、风管布置方案以及空调方案建立了与实船等比例的模拟舱室，包括11个新建模拟舱室。通过实验验证了可通过改变模拟舱室中的模拟负荷发生器的设定负荷，得到了与邮轮对应舱室较为吻合的响应特性，验证了模拟舱室的室温响应模型的准确性。

Abstract: The heat transfer mechanism of the cruise ship cabin and the load change of the cruise cabin were analyzed. The corresponding transfer function was derived based on the sources and principles of heat entering the room and being discharged outside the room and the law of energy conservation. Simulink software was used to establish the room temperature response model of the cabin, and the response to changing the ship speed was explored, the influence of heading on the room temperature of the interior and exterior cabins, and based on the size, equipment, air duct layout plan and air-conditioning plan of the actual cruise ship, a simulated cabin with the same proportion as the real ship was established, including 11 new simulated cabins. Through experiments, it was verified that by changing the set load of the simulated load generator in the simulated cabin, response characteristics that are consistent with the corresponding cabin of the cruise ship were obtained, verifying the accuracy of the room temperature response model of the simulated cabin.
