舱室换气模型研究

Research on the Model of Cabin Ventilation

摘要: 舱室换气问题在船舶、潜艇、航天器等封闭环境中具有重要的意义，良好的舱室换气不仅可以提高居住舒适度，更重要的是保障人员身心健康，甚至是提高生产力、战斗力的重要因素。微元法是微积分理论中重要的数学思想方法，也是从部分到整体的思维方法，可以解决很多物理和实际问题。本文利用微元法，求出了舱室内即时CO₂浓度模型，从而建立了保持舱室正常使用的换气通风量数学模型，初步解决了一种舱室换气问题，可为相关领域的研究和实践提供有益的参考。

Abstract: The problem of cabin ventilation is of great significance in enclosed environments such as ships, submarines, and spacecraft. Good cabin ventilation not only improves living comfort, but more im-portantly, it is an important factor in ensuring the physical and mental health of personnel, and even improving productivity and combat effectiveness. The microelement method is an important mathematical method in the theory of calculus, as well as a thinking method from part to whole, which can solve many physical and practical problems. In this paper, the micro-element method is used to derive the instantaneous CO₂ concentration model in the cabin, thus establishing a mathe-matical model for maintaining normal ventilation in the cabin. This preliminary solution to a cabin ventilation problem can provide useful reference for research and practice in related fields.
