家用变频空调制冷舒适节能控制实验研究

摘要

This paper aims at the experimental research on refrigeration control of comfort and energy conservation at household inverter air conditioner. When the refrigeration is operating, and the outdoor condition is certain, its operating frequency is inclined to a positive correlation with temperature differences indoor. Through simulating the inverter air conditioner in different working conditions, and contrasting the refrigeration effects, it found that in most working conditions, lowering slightly the high frequency of refrigeration, the effect of temperature drop is appropriate, and the comfort level is more closer to the thermal comfort requirement of human body that defined in the ISO standard, and the operation is more energy-saving.%本文针对家用变频空调在制冷运行时的舒适性与节能性进行实验研究。目前变频空调在制冷运行时，当室外工况一定，其运行频率更倾向于与室内温差成正相关的控制关系。通过试验模拟变频空调在不同工况条件用户使用的制冷温降效果，发现在大部分工况条件下，将现有制冷高频运行时的频率略为降低进行控制后，其温降效果不变，舒适度则更接近ISO标准中定义的人体热舒适性要求，且运行更为节能。
