夏热冬冷地区基于座位的个性化供暖系统研究
Seat-based personalized heating systems in hot summer and cold winter zone
摘要：
在较低室内温度（12~16 ℃）下，对由加热地板与座椅（普通座椅与保温座椅）构成的个性化供暖系统对人体整体、局部热感觉的改善情况进行了研究。选取10名大学生进行了热感觉投票，测量了房间及座位附近的温度，并与分体式空调供暖能耗进行了对比。结果表明：加热地板的使用能够提高人体热舒适性，而增加保温座椅更有效果；12 ℃时，加热地板+普通座椅仅改善了足部热感觉，与无加热地板相比改善效果甚微；加热地板+保温座椅对于提升受试者的下半身热感觉更有效果；采用加热地板+保温座椅，14 ℃时腹部、臀部和足部可达到热中性，16 ℃时足部和小腿感觉到稍热；房间内设置2个工位时，加热地板+保温座椅与分体式空调相比，节能率为63.1%。
Abstract：
Investigates the improvement effect of personalized heating systems consisting of the heated floor and a chair (an ordinary chair or an insulated chair) on the overall and local thermal sensation of the human body at lower indoor temperatures (12 to 16 ℃). During the experiment, selects ten college students to vote on the thermal perception, measures the temperatures in the room and near the seat, and compares the energy consumption of the personalized heating system with that of the split air conditioner for heating. The results show that the use of heated floor can improve the thermal comfort of the human body, and the addition of an insulated seat is more effective. At 12 ℃, the heated floor plus ordinary chair only improves the thermal sensation of foot, and the improvement is slight compared with unheated floor. The heated floor plus insulated chair is more effective in improving the thermal sensation of the subjects’ lower body. Using the heated floor plus insulated chair, the abdomen, buttocks and feet can reach thermal neutrality at 14 ℃, and the feet and calves may feel a little hot at 16 ℃. When two workstations are arranged in the room, the energy saving rate of heated floor plus insulated chair is 63.1% compared with that of the split air conditioner.
