造成墙体一侧空气温度为谐波变化,另一侧空气温度为恒定的传热状态,对研究墙体不稳定传热热工特性,特别是空调负荷不稳定计算所需的两个重要参数v、ζ,有着重要意义。对用微机控制空气温度呈谐波变化进行的尝试,经过努力,初步实现了制造谐波扰量的目的,从而解得墙体不稳定传热热工特性。试验墙体是由承重粘土空心砖砌制而成,同时还用相同结构的空心聚苯乙烯砌制墙体进行类似的
The air temperature on one side of the wall is a harmonic change, and the air temperature on the other side is a constant heat transfer state. It is an important parameter for investigating the unstable heat transfer characteristics of the wall, especially for the calculation of the instability of the air conditioning load. v. He is very important. For the attempt to control the harmonic change of the air temperature with a microcomputer, efforts have been made to initially realize the purpose of manufacturing the harmonic disturbance, so as to solve the unstable heat transfer characteristics of the wall. The test wall is made of load-bearing clay hollow bricks and similarly constructed with the same structure of hollow polystyrene masonry walls.
