为了解高大工业厂房中散热器与吊顶辐射采暖联合供热温度特性,通过对某煤矿高大辅助车间的实测,得到两者联合作用下的室内空气温度、黑球温度及地面温度参数。测试结果显示:1)厂房中部温度场稳定,分层均匀,而靠近外围护结构处室内温度场不稳定。2)室内竖向梯度介于0.33~0.73℃/m之间,其呈现的规律为:第一跨>第二跨>第三跨;工作区温度梯度在0.23~1.04℃/m之间,温差小,热舒适与相关文献相符。3)1.5 m高度处黑球温度比对应空气温度约高出1.8~2.7℃。
In order to understand the temperature characteristics of radiant heating combined heating radiator and ceiling radiant heating in tall industrial buildings, the indoor air temperature, black-ball temperature and ground temperature parameters under the combined effect of the two are obtained through the measurement of a large auxiliary workshop in a coal mine. The test results show that: 1) The temperature field in the central part of the plant is stable and well-layered, while the indoor temperature field near the outer envelope is not stable. 2) The indoor vertical gradient ranged from 0.33 to 0.73 ℃ / m, and the regularities were as follows: the first span> the second span> the third span; the working zone temperature gradient was between 0.23 ~ 1.04 ℃ / m, the temperature difference Small, thermal comfort and relevant literature. 3) At 1.5 m height, the black ball temperature is about 1.8 ~ 2.7 ℃ higher than the corresponding air temperature.
