客船上层建筑被动式节能措施节能效果分析

Analysis of Energy Conservation for Passive Measures in Passenger Ship Superstructure

为了计算分析客船上层建筑被动式节能措施的节能效果,新构建包含热工特征和形态特征的被动式冷/热负荷计算模型,并用于计算某客滚船一餐厅在不同被动式节能措施下的冷/热负荷指标,结果表明:在炎热条件下,建议采用Low-E玻璃、遮阳和减小玻璃面积比;在寒冷条件下,建议采用中空玻璃、减小体形系数和积极使用太阳辐射热。

In order to calculate and analyze the energy conservation for passive measures in passenger ship superstructure,a passive cooling/heating load calculation model is newly constructed,which includes thermal characteristics and morphological characteristics.It is used to calculate the cooling/heating load index of a restaurant in one Ro-Pax ship under different passive energy conservation measures.The results show that:in hot areas,use Low-E glass,shading means and reduce the glass area ratio;in cold areas,use glass with low heat transfer coefficient and reduce the shape factor,and actively use solar radiation heat gain.
