也就是说,如果您使用不超过五个小时,变频空调省电的优势根本显示不出来。在这种情况下,那咱们还有必要选购变频空调吗?变频空调的优点变频空调相对定频空调来说噪音更低,控温的度高,调温的速度快,电压的要求比较低,环境温度要求比较低,保持室内温度的恒温性等等,这些优点都比它在省电这个优势上的呼声要高。控温度高这个优势,可以让我们不会遭遇到房间内忽冷忽热的情况,大大提高了空调房内的舒适性。总的来说,针对国人使用空调的习惯,变频空调为您省出差价都有点困难,所以您就可以把变频空调省钱这件事情忽略不计了。

主电源指示灯不亮时,检查指示灯丝及室内配电板丝是否熔断,同时检查电源线是否接触良好,如丝断则应更换丝并保持电路畅通。还应检查真空泵表及油压指示值,如油压过高而主机也不能启动,必须检查各油路是否堵塞,特别是节流小孔是否畅通,如不畅通应清洗使之畅通。轴承损坏或转动受阻,全自动离心机轴承内缺油或轴承内有污垢较多而引起摩擦阻力增大,电机达不到额定转速,应及时清洗或更换轴承。整流子表面有一层氧化物,甚至烧成凹凸不平或电刷与整流子外缘不吻合也可使转速下降,应清理整流子及电刷,使其接触良好。
