摘要
能源合理利用可以降低能耗,提高效率,因此需要对机房空调流体进行模拟和研究。根据高度、温度、风速和距空调位置几个参量,利用Matlab数学软件、第二型曲面积分、Simple算法、线性回归、k~ε两方程紊流模型,建立室内空气浓度分布图和室内热流量分布状况,整合机柜任务量对温度极值点的权向量,得出机柜任务量与温度的相关度及最低温度分配方案。数据分析表明:通过控制空调的冷通道出风口风速可以调节室内温度,并确定在不同任务量条件下最优空调送风速度和送风温度方案。
If energy is used rationally,energy consumption and efficiency can be reduced.Therefore,it is necessary to simulate and study the air conditioning fluid in the equipment room.Based on several parameters such as height,temperature,wind speed and air conditioning position,Matlab mathematical software,second type surface integral,SIMPLE algorithm,linear regression,two-equation turbulence model are used to establish the indoor air concentration distribution map and Indoor heat flux distribution.We integrate the weight vector of the equipment cabinet with the extreme value of the temperature and obtain the correlation between the task of the equipment cabinet and the temperature and the distribution scheme of the minimum temperature.The data analysis shows that the temperature of the indoor air can be adjusted by controlling the wind speed of air outlet of the cold air in the air conditioner,and the optimal air distribution rate and air supply temperature of the optimal allocation scheme under different task conditions are clarified.
