摘要(Abstract):

针对中国厨房炊事余热大,室内热环境不舒适的现状,提出一种简易的新型厨房顶板辐射空调模型。在厨房的天花板上安装了一个简单的辐射散热面板装置,并加装辅助排风管。基于计算流体动力学CFD方法,对厨房内双眼灶单开和双开时的室内及顶板温度分布进行了数值模拟,并通过在长沙多层公寓楼的家用厨房的实验测量验证。结果表明,炉灶双开时气流温度略高于单开3~4 K,烹饪时厨房温度约为301 K(27.85℃),低于客厅温度302 K(28.85℃),从而达到更舒适的热环境。天花板上的辐射冷却被证明是厨房冷却的重要因素。
In view of the situation of large amount of residual heat in Chinese kitchen and comfortable indoor thermal environment,a simple radiant cooling panel air conditioning model was proposed.A simple radiant cooling panel device was installed on the kitchen ceiling and an auxiliary exhaust pipe was equipped. Based on CFD(computational fluid dynamics) method,the temperature distributions in the room and in the ceiling of the kitchen with one burner and two burners of a double-burner stove burning were numerically simulated. The model was validated by experimental measurements in kitchens in a multi-storey apartment building in Changsha,China. The simulation results show that the airflow temperature when both burners of the stove were used is 3~4 K slightly higher than that when one burner was used. The temperature of the kitchen during cooking was about 301 K(27.85 ℃),which is lower than the living room temperature 302 K(28.85 ℃),therefore,a more comfortable thermal environment was achieved. The radiant cooling in the ceiling was proven to be an important contributing factor in the cooling of kitchen.
