基于PMV/PPD的船舶舱室热舒适探讨

Review of Thermal Comfort Based on PMV/PPD in Cabins of Vessels

对某1000t巡逻船各舱室内的最佳温度加以估计。适当的修正陆上人员穿着和活动的规则和标准,调查了该巡逻船的各种人为因素。驾驶室一年四季总的服装热阻分别为0.097,0.079,0.096,0.130 m2℃/W,生活区一年四季总的服装热阻分别为0.067,0.059,0.084,0.101m2℃/W。培训室的新陈代谢率为228.04 W/m2,机舱室和辅机室的高于100 W/m2。驾驶室和居住区的新陈代谢率分别为78.14和44.45 W/m2。基于人为因素,驾驶室和居住区的最佳温度分别为23℃和29℃。因此,基于PMV-PPD设计的空调系统可以节省6℃的能量。

This study has focused on the evaluation of the optimal temperature in each cabin of one maritime patrol vessel.We aptly modified the inland indoor items and criteria of clothing and activities,and then investigated the human factors in the cabins of the maritime patrol vessel.The total thermal resistance of clothing in the wheelhouse was 0.097,0.079,0.096 and 0.130 m2℃/W and that for the accommodation areas was 0.067,0.059,0.084,and 0.101m2℃/W in spring,summer,fall,and winter,respectively.The metabolic rate was 228.04 W/m2 in the training room and above 100 W/m2 in the engine room and auxiliary machine room.In the wheelhouse and accommodation,the metabolic rate was 78.14 and 44.45 W/m2,respectively.Based on human factors,the optimum temperature was 23℃ in the wheelhouse and 29℃ in the accommodation.Therefore,6℃ of energy can be saved in case of PMV/PPD-based air conditioning.
