风机盘管湿膜加湿器对房间温湿度影响的实验研究

Experimental research on the influence of room temperature and relative humidity by fan coil unit with wet film humidifier

传统的风机盘管没有加湿功能,不设新风的风机盘管空调系统冬季室内湿度较小,不能满足舒适度要求。带湿膜加湿器的风机盘管可以很方便地对房间进行加湿,改善室内湿度场,提高室内环境的舒适性。本文通过对使用风机盘管湿膜加湿器的房间进行实验研究,分析湿膜加湿器开启后室内温湿度场的变化情况,得到湿膜加湿器对室内温湿度场的影响规律。研究结果表明,风机盘管湿膜加湿器加湿效果较好,室内相对湿度从30%提高到55%,室内各点的温度略有下降,室内温湿度场的分布规律不变。

Traditional fan coil unit has no humidifying function. In winter, the relative humidity of the room which is conditioned by fan coil air conditioning system without fresh air is too low to meet the comfort requirements. But those with wet film humidifier can easily humidify the room and improve the indoor comfort. This article makes an experimental study on the room temperature and relative humidi- ty fields conditioned by fan coil with wet film humidifier, analyses the room temperature and relative humidity changes with the wet film humidifier operating and gets the influence rule of indoor tempera- ture and relative humidity by using wet film humidifier. The results show that the fan coil units with wet film humidifier have better humidifying effect. The indoor relative humidity increases from 30% to 55% and the temperature of each measuring point decreases slightly. The distribution of the indoor temperature and relative humidity is constant.
