一种具有回热功能的呼吸鼻式新风装置实验与研究

为提高室内空气品质和节约建筑能耗，文中设计了一种具有回热功能的呼吸鼻式新风装置.它利用在通风道中设置储热体的方法，将废气中的部分有效热能保存下来，并利用新风送回室内，从而减小建筑能耗.介绍了装置的工作原理和性能测试方法，并在模拟房间内，分别对冬季供热和夏季供冷两种情况下该呼吸鼻的储热体温度变化规律、换热效率和节能量进行了实验测试.实验结果表明，本装置每小时换风量达到60 m3，冬季可节省新风热负荷约280 W，夏季节约新风冷负荷270 W，装置的热回收效率可达80%. 

Experiment and Research on New Respiratory Type of Fresh Air Device with Heat Recovery Function

In this paper,a new respiratory type of fresh air device with heat recovery function was designed to reduce the building energy waste.Its process was arranged to save part of the heat energy in the exhaust gas and send it back to the room,when supplying fresh air with a heat storage device installed in the ventilation duct.Firstly,the work principle and the performance test method were introduced.Then,two kinds of situations,such as winter heating and summer cooling,were respectively simulated in a simulation room to test the temperature variation regularity of the heat storage device,heat transfer efficiency and energy saving.The experimental results show that,the ventilation of the device can reach 60 m³ per hour,fresh air thermal load can be reduced about 280 W in winter and the fresh air cooling load can be reduced about 270 W in summer,its heat recovery efficiency can reach 80%.
