目前市场上厂家所宣称的“仿自然风”在频谱特征上与典型自然风存在很大差距,本文根据动态送风装置的研究现状和发展情况设计了一种基于直流无刷电机控制的工位型个体化动态送风装置。性能测试表明装置产生的仿自然风已经非常接近于真实自然风信号。经过人工气候室的人体投票实验,验证了在偏热环境中,装置产生的仿自然风对人体TSV/TCV的改善效果要优于稳态机械风,采用“偏热环境+动态送风”的空调方式可以实现与“传统稳态空调环境”相接近的热舒适性。
At present, the declared “” imitation of natural wind by the manufacturer on the market is far from the typical natural wind in terms of spectral characteristics. According to the research status and development of the dynamic blower, this paper presents a design based on the brushless DC motor control Station-type individual dynamic blowing device. Performance tests show that the natural wind generated by the device is very close to the true natural wind signal. After human body voting experiment in the artificial climate room, it is verified that the natural wind generated by the device improves the TSV / TCV of the human body better than the steady mechanical wind in the partial heat environment, and adopts the mode of “hot environment + dynamic air supply ”The air-conditioning method can be achieved and “ traditional steady-state air-conditioned environment ”close to the thermal comfort.
