摘    要:为测试蓄冰空调不同工况(包括不同剩余冰量、循环风量)对避难硐室生存区热舒适性的影响,测试了不同工况时蓄冰空调的实际制冷性能;在此基础上采用RNGκ-ε模型和SIMPLE算法模拟分析了蓄冰空调不同工况时某50人避难硐室生存区内速度场、温度场及热舒适性的变化情况。研究表明,空调剩余冰量越多、循环风量越大,空调实际制冷功率越大,生存区热舒适性越好;同时还提出了蓄冰空调最低循环风量要求的工程计算公式。

关 键 词:避难硐室  蓄冰空调  蓄冰量  循环风量  热舒适性

Effect of ice storage air conditioning condition on human thermal comfort in refuge station living area
Abstract:The effect of two main factors,including remaining ice volume and air flow rate,on refrigeration performance of ice storage air conditioning for refuge station was tested.On the basis,adopting RNG κ-ε model and SIMPLE method,the distribution of velocity,temperature and thermal comfort of living area in a refuge station that accommdate 50 individuals under different operating conditions of ice storage air conditioning was simulated.Research results indicat that conditioning refrigeration power increases with with the increase of remianing ice volume and air flow rate,and the thermal comfort of the living area is also improved.Meanwhile,a formula of minimum air flow rate for design calculation was also proposed in the end.
Keywords:refuge station  ice storage air conditioning  remaining ice volume  air flow rate  thermal comfort
