船舶舱室空调热舒适性评价指标及其微气候参数优化

船舶空调舱室热舒适性是影响船员工作效率和生活品质的重要因素。文章分析了影响空调舱室热舒适性的诸多因素,讨论了PMV (Predicted Mean Vote 预测平均满意值) 指标的作用及其运算方法。建立了舱室简化模型,并结合实际海况,计算了不同温度、相对湿度组合下的PMV,PPD(Predicted Percentage of Dissatisfied, 预测不满意率)值及系统热负荷,分析了舱室内温度、相对湿度对其热舒适性及能耗的影响。在满足热舒适性指标的情况下,优化船舶空调设计参数以实现节能的目的。文章对船舶空调的设计及舱室温微气候参数的选择具有借鉴意义。

Thermal Comfort Index of Marine Cabin Air-conditioning System and the Optimization of Cabin Climate

thermal comfort of air-conditioned marine cabin is the important impact factors of the crew working efficiency and quality of life. Influence factors of thermal comfort of air-conditioned marine cabin were analyzed and the PMV PPD was discussed. A marine cabin model, combined with the real ocean conditions, was established to emulation and discuss. Based on the various temperatures and relative humilities, the PMV-PPD index and the thermal load were calculated to analyze. Under the requirement of the thermal comfort index, the air conditioning design parameters were optimized to achieve the purpose of energy conservation. The work was the significant reference for marine air conditioning design and operation.
