Summary

In order to reduce energy consumption of air-conditioner during night, one zoning air-conditioner fixed on the bed, namely bed AC, is developed based on Peltier effect. The bed AC is equipped with a heating unit on the foot part and a cooling unit on the head part. It not only meets the thermal comfort of a bed, but also can create a comfortable environment about "warm foot and cool head". In winter, bed AC can maintain bed air temperature at 22°C, and its power is about 0.1kW - 0.2kW, and foot air temperature is approximately 6°C higher than that of head. In summer, if room temperature is lower than 30°C, bed AC can keep bed air temperature at 28°C, and its power varies from 0.06kW to O.12kW, and head air temperature is nearly 1.5°C lower than that of foot. By system simulation, the energy-saving performance is also studied. It can be found that energy saving rate of bed AC in winter and summer sleeping time is 52% and 42% respectively, compared with traditional split air-conditioner.
