摘　　要：为了得到高温高湿造纸工业厂房内温湿度分布规律,对不同地区、不同季节的5个造纸厂房热湿环境进行了现场实测与调查。通过对测试数据的分析,得出厂房温度沿高度方向分层分布的规律,而且夏季温升明显大于冬季温升。推导得出造纸厂房6m高度以内冬夏季温度在垂直方向上随高度变化的拟合关系式。发现相对湿度与含湿量随高度分层分布的特性,但两者并不完全一致,且两者分布规律与厂房纸机设备散湿量及其散湿方式密切相关。总结出对人体有害的工作区域。所得到的温湿度分布规律为优化造纸车间通风系统设计、改善工人工作环境和设备运行环境提供了参考依据。This paper is aimed at introducing the findings from our measurement and investigation on the high temperature and humidity environment for paper-making plants. In hoping to find out the distribution regularity between the temperature and humidity in the papermaking workshops with hot and humid environment, we have carried out field measurements and investigations of five paper-making plants in different regions all over the country in different seasons. The resuits of our measurements and analysis reveal some regular results between the temperature and the height of the workshop buildings of such paper-making plants. To be exact, conclusions have been made that the temperature in such buildings increases with the height verti- cally no matter whether in summer or in winter, but the temperature in summer rises much more remarkable in comparison with that in winter. Moreover, a comparative formula has been derived with the increase of the height as compared with that of the temperature. However, the formula is just applicable for a building height below six meters. In addition, we have also worked out the relative humidity and the humidity ratio to the comparative temperature. Actually, the relative humidity and humidity ratio can be taken as the hierarchical distribution features, though they are not entirely in proper ratio to each other, for the temperature is not only related to the humidity but also to the temperature change. In some ways, it can be said that the higher the temperature, the lower the relative humidity with the humidity ratio being constant. Furthermore, both the relative humidity and humidity ratio distribution characteristics are closely related to the moisture diffusion degree and the mode of paper machines in the workshops. And, finally, we have also made believe that such a kind of hot and humid environment is harnfful for the workers to stay long. In one word, the above investigation and analysis have done on temperature and humidity distribution characteristics are expected to provide a
