本文建立了毛细管平面辐射空调系统室内新风气流组织的物理和数学模型,采用CFD软件对毛细管平面辐射空调室内气流组织的温度场和CO2浓度场进行了模拟,得出室内温度场最大垂直温度梯度为1.7℃/m,垂直高度为0.1 m的水平面上的最大水平温差约为1.1℃;新风送风口最佳位置应为距离地面0.1 m处。
In this paper, the physical and mathematical models of indoor fresh air flow in capillary air-conditioning system were established. The CFD software was used to simulate the temperature field and CO2 concentration field of air-conditioned indoor air-conditioning system. The maximum vertical temperature gradient of indoor temperature field was 1.7 ℃ / m, vertical height of 0.1 m on the level of the maximum horizontal temperature difference of about 1.1 ℃; fresh air outlet should be the best location 0.1 m above the ground.
