严寒地区车库采用散热器地沟敷设供暖研究

Study on Garage Heating by Radiator Gutter in Severe Cold Zone

在严寒、寒冷地区地面具有高大空间特点的停车库供暖问题上,提出了一种不受外墙敷设空间影响的地沟散热器安装供暖方案,并利用Airpak气流组织模拟手段,对供暖方案的供暖效果进行计算。通过计算结果可知,采用散热器地沟安装供暖方案,散热器表面能够产生稳定的上升气流,空气流动最大风速达到0.47m/s,车库内部整体温度能够达到采暖设计温度;考虑外窗、外门及外墙内壁温度较低,对于车库内部安装的宜结冻管道、设备应适当保持一定距离。

This paper presents a heating scheme for parking garages with high space on the ground in cold and cold areas,which is not affected by the outer wall laying space.The heating effect of the heating scheme is calculated by Airpak air flow organization simulation method.Through the calculation results,it can be seen that the radiator surface can produce stable updraft when the heating scheme is installed in the radiator trench.The maximum wind speed of air flow reaches 0.47m/s,and the overall temperature inside the garage can reach the heating design temperature.Due to the low temperature of the outer Windows,outer doors and outer walls,the frozen pipes and equipment installed inside the garage should be properly kept at a certain distance.
