参考来源 - 全集成连续时间滤波器的设计Results indicate that the lower frequency the air-conditioner runs at, the lower heating capacity it produces, the higher COP it possesses. The frequency conversion air-conditioner runs at low frequencies with higher efficiency, which is the main reason of energy-saving.
结果表明:变频空调器的制热量随运行频率的降低而减少,在低频运行时,制热量变化大大减小基本保持不变;而COP值随频率的下降始终呈上升趋势,可见变频空调器在低频运行时经济性较好,这是变频空调器节能的主要原因所在。
