摘要
介绍了酒店大堂的分层空调系统设计,并对大堂在有、无室内浮雕装饰限制条件下夏季温度场和速度场进行数值模拟.模拟结果验证了大堂采用分层空调系统的合理性.模拟结果还表明在室内装修限制条件下(方案1),大堂局部温度偏高或偏低,风速偏大,而且耗冷量比无室内浮雕限制下的空调系统(方案2和3)大2%以上.3种方案对比分析结果还表明室内气流的均匀性主要受送风方式影响.
The paper presents the design of delaminated air-conditioning system for the hotel＇s lobby briefly, simulates the air distribution constrained by indoor embossment decorations and the air distribution not so limited respectively in summer. The simulation results verify the reasonableness of adopting the delaminated air-conditioning system. The results show that under the indoor decoration restrictions the lobby＇s local temperature is either higher or lower than those required by the design codes ,and the local air speed is higher. Moreover,the cooling load is over 2 percent more than that with no indoor decoration restrictions. The simulation results also show that the uniformity of indoor air flow is mainly affected by air supply method.
