对安装在车库设施中的燃气辐射供暖系统进行了现场试验。该系统由一根26米（85英尺）长、0.078米（3.5英寸）宽的金属管、一个反射器总成、两个燃烧器和一台抽风机组成。管子从倾斜的天花板上水平悬挂，管子到天花板的距离从0.61米（2.0英尺）到2.1米（7.0英尺）不等。从地面到管道的距离为4.6米（15英尺）。一个反射器组件悬挂在管子上方，将辐射热向下引导。一个燃气燃烧器在管道的入口处提供火焰，而一个抽风机将燃烧气体排放到室外。在白天车库空无一人的时候，以及晚上车库里挤满了车辆的时候，对供暖系统进行了瞬态和稳态实验。研究了温度随管道长度的变化以及墙壁和地板上的温度分布。当加热器循环打开和关闭时，在多个位置确定空气分层。 此外，还将空气分层与强制空气加热装置进行了比较。单位:双引文:研讨会，ASHRAE交易，1986年，第92卷，pt。1B，旧金山

A field test was performed on a gas-fired radiant heating system installed in a garage facility. The system consisted of a metal tube that was 26 m (85 ft) long and 0.078 m (3.5 in) wide, a reflector assembly, two burners, and an exhauster. The tube was suspended horizontally from a sloping ceiling with the distance from the tube to the ceiling varying from 0.61 m (2.0 ft) to 2.1 m (7.0 ft). The distance from the floor to the tube was 4.6 m (15 ft). A reflector assembly was suspended over the tube to direct the radiant heat downward. A gas-fired burner fed a flame at the inlet of the tube, while an exhauster vented the combustion gases to the outdoors.Transient and steady-state experiments were performed on the heating system during the day when the garage was empty and at night when it was filled with vehicles. The temperature variations with tube length were examined as well as the temperature profiles on the walls and floor. The air stratification was determined in several locations as the heater cycled on and off. An air stratification comparison with a forced-air heating unit was also made.Units: Dual
