改善火炕炕面温度分布技术模拟

Simulation study on the technology for improving the temperature distribution of Kang surface

摘要:

为了使火炕的表面温度分布均匀,提高室内环境的热舒适性,提出了倾斜布置炕板来改善炕面温度分布的不均匀性．通过对炕板倾斜程度不同的落地炕和吊炕进行数值模拟,结果表明:当落地炕的炕头粘土层厚度为80 mm、炕梢粘土厚度为20 mm时具有相对最佳的取暖效果;当吊炕的炕头粘土层厚度为80 mm、炕梢粘土厚度为20 mm时具有相对最佳的取暖效果．

Abstract:

To solve the problem of inhomogeneous distribution of Kang′s surface temperature and poor indoor thermal comfort, this paper proposes a method to incline the Kang board. By the numerical simulation of grounded Kang and elevated Kang with different oblique degree of Kang board, it is found that when the claypan thickness at the head/end of the Kang is 80/20 mm, the Kang has the best heating effect.
