低温供热对室内舒适性影响的数值模拟

利用CFD技术,对二次网设计供回水温度降低后散热器供暖房间的舒适性进行了模拟分析,结果表明,随着二次网设计供回水温度的降低,人员主要活动区域内的温度梯度减小,温度分布更均匀,舒适性得到提高。

By using CFD technology, the comfortableness of the radiator heating room is simulated after the temperature of the secondary network design is reduced. The results show that with the decrease of the supply and return water temperatures of the sec-ondary network design, the temperature gradient in the main moving area of the personnel decreases. The temperature distribution is more uniform and the comfortability is improved.
