本文基于帕尔贴效应设计了一种冷暖型床体局部空调，简称空调床。空调床由床头制冷装置和床尾供暖装置构成，使床内形成“头凉脚暖”的温度分布。冬季开启供暖模式，可使床内温度达到22°C左右，与房间空调相比，节能率约85％，同时使脚部温度比头部温度高约6°C夏季室温低于30°C时，空调床单独运行，使床内温度降低至28°C左右，节能率约80％。当室温大于30°C时，空调床与房间空调联合运行，与房间空调单独运行相比，节能率为约12％。夏季床内脚部温度比头部温度高1．5°C。
A novel bed zoning air-condition, namely bed AC, was developed based on peltier effect. The Bed AC contains two parts, one is a heating unit on the foot part, and another is a cooling unit on the head part, which can realize ＂warm feet and cool head＂. In winter, heat unit operated to maintain bed air temperature around 22°C, and its electrical saving rate was 85%, compared with room AC, and foot air temperature was approximately 6°C higher than that of head. In summer, when room temperature was lower than 30°C, cool unit worked to keep bed air temperature around 28°C, and its energy saving rate was about 80%, and head air temperature was nearly 1.5°C lower than that of foot.. When room temperature was higher than 30°C, bed AC needed to cooperate with room AC, and their total energy saving rate was about 12%, compared with only room AC.
