Unlike general ventilation, personalized ventilation can improve thermal comfort and conserve energy based on individual differences. It can also provide every individual the ability to control fresh air exposure and ensure good indoor air quality. However, determining how to improve air supply efficiency while avoiding a draft sensation is still a difficult question. This paper introduces a body movement‐based personalized targeted air supply device. Two indices, size target value and velocity target value , are introduced to evaluate the degree to which the created flow field reaches the desired level. Additionally, the air supply effect of the device is compared with that of other devices. This research shows that the personalized targeted air supply device can successfully deliver air to the target area and improve air supply accessibility in the target area. The multinozzle coupling air supply mode produces a flow field air velocity of approximately 0.3 m/s, thus effectively avoiding a draft sensation. Compared with that of other personalized nozzles, the energy consumption is reduced significantly, by 88.2%, while the air supply accessibility can be increased by 48% with equivalent energy consumption.

基于人体运动捕捉的个性化定向供气装置研究[J].

与一般通风不同，个性化通风可以根据个体差异提高热舒适度和节约能源。它还可以为每个人提供控制新鲜空气暴露并确保良好室内空气质量的能力。然而，如何在避免风感的同时提高送风效率仍然是一个难题。本文介绍了一种基于身体运动的个性化定向供气装置。两个指标，尺寸目标值和速度目标值, 用于评估创建的流场达到所需水平的程度。此外，该装置的送风效果与其他装置进行了比较。本研究表明，个性化的定向送风装置可以成功地将空气输送到目标区域，提高目标区域的送风可达性。多喷嘴耦合送风方式产生约0.3m/s的流场风速，有效避免气流感。与其他个性化喷头相比，能耗显着降低88.2%，而同等能耗下，送风可达性提高48%。
