蒸发冷却空调房间气流组织的数值模拟

Numerical Simulation of Airflow in Evaporative Cooling Room

应用k-ε二方程湍流模型和数值模拟方法对蒸发冷却空调房间的三维温度场,速度场以及热舒适指标进行了模拟,研究结果表明,蒸发冷却空调器能够有效地改善室内热环境,较好地满足了人体热舒适在通风和空气调节方面的要求。常规满足最不利条件时空调要求的设计方案,适用于蒸发冷却空调的设计。

By using k-ε double-equation turbulent model and numerical simulation methods, the three-dimensional temperature field, velocity field and thermal comfort index were numerically calculated in evaporative cooling room. The result indicates that evaporative cooler can effectively improve the thermal environment in the room and meet the demand of thermal comfort of occupants. The design method for general air-condition system applies the evaporative cooling system as well.
