摘要
传统风管机因其安装位置较高并且出风口是水平出风,导致制热时热风浮在房间的上部空间难以落地,容易出现“头热脚冷”的问题。针对上述问题,根据人体对冷热风的舒适性要求,创新性地提出可逆送风技术,通过驱动结构带动风机蜗壳旋转,制冷时蜗壳侧向水平出冷风,制热时蜗壳旋转至出口朝下位置,实现竖直向下出热风。制冷时冷风平吹,房间内冷气流自然沉降实现淋浴式制冷,制热时热风竖直向下直吹地面,实现暖从足起。与常规的风管机相比可逆送风风管机热风落地更快,人体脚部位置平均温度提升约2.5℃。
Due to the high installation position of traditional duct air conditioners and the horizontal air outlet,when heating,the hot air floats in the upper space of the room and is difficult to reach the ground,which easily leads to the problem of"hot head and cold feet".In response to the above issues,based on the human body's comfort requirements for hot and cold air,an innovative reversible ventilation technology was proposed.This technology achieves the rotation of the fan casing through a driving mechanism.During cooling,the casing discharges cold air horizontally to the side;during heating,the casing rotates to an orientation with the outlet facing downward,thus enabling the discharge of hot air vertically downward.During cooling,the cold air is gently blown horizontally,and the cold air flow naturally settles in the room,achieving shower-type cooling.During heating,the hot air is vertically blown downward directly onto the floor,achieving warmth starting from the feet.Compared with conventional duct fans,the reversible air supply duct fan can deliver hot air to the ground more quickly.The average temperature at the human foot position increases by approximately 2.5℃.
