摘要:
本文针对车辆运转耗氧导致登陆舰车辆舱内含氧量低,计算柴油车辆发动机耗氧,并基于全面通风计算方法,考虑送风、排风温差对全面通风方程影响,建立内有强热源的车辆舱环境空气含氧量的理论计算模型。并结合某车辆舱实况,采用该含氧量模型计算在无通风、有通风条件下,车辆舱内空气含氧量、空气温度随时间变化规律,并对比分析温差修正前后的计算结果。研究结果表明:在已知送风参数条件下,计算得到了人员在车辆舱内安全工作时所需的通风量;风量一定情况下的车辆舱内含氧量变化规律;以及在不同风量下温差修正的系数、而且温差修正系数随着温差增大而不断增大。为分析及防止车辆舱内工作人员缺氧提供了理论计算参考。
Abstract:
? Vehicle hold of landing platform dock (LPD) is the cabin to hold vehicles such as tanks, armored vehicles, and other engineering vehicles. As engines of vehicles started, oxygen inside the vehicle hold was heavily consumed, and vehicle emissions are released. In order to ensure adequate oxygen supplied, first the vehicle oxygen consume was analyzed first, and then the calculation model of oxygen concentration was built to analyze the oxygen content inside the vehicle hold of LPD based on the general ventilation equation. The temperature difference between supply air and exhaust air was considered while building the calculation model. Furthermore, a case was analyzed by this model. The results show the law that ventilation rate or temperature varies by time, and that the coefficient of temperature correction varies with different ventilation rate. The result is much helpful and valuable for human safety protection by preventing hypoxia inside the vehicle hold
