家用中央空调比传统空调耗电吗,如何省电?

 1、中央空调是不是耗电,先看能耗比

  随着各大厂家在中央空调的大投入研发,中央空调的能效比已经达到超过柜式、分体式等普通空调的水平。一般家用分体空调的能效比是2.3~2.8左右,而中央空调则能达到3.0以上。这意味着在同一个温度下,家用中央空调的耗电量要低于普通的柜式、分体式空调。

  此外,中央空调还可以配壁挂炉使用,也可以借助地源热泵技术,将能效比提升至5以上。所以从这点来说,家用中央空调的耗电量并不大。

  2、比传统空调更耗电是个误区

  从功能上来说,一台家用中央空调相当于几台壁挂和柜式机,其用电量小于每个房间装一台空调的用电量之和,效果却比装几台的效果要好,运行费用大大低于分体空调;中央空调制冷站可直接控制制冷机的开停时间和冷量大小,可根据气候变化进行调整,以节约运行电费。

  从以上分析来看,家用中央空调耗电量并不会比壁挂、柜式分体机多,且电费远比供暖费低得多。无论是从性能、外观还是整体使用效果上,中央空调都优胜于传统空调。

  3、那空调怎样使用才能省电呢?

  其实,耗电量与室内人数、房间密闭性等多种因素有关。一般来说,空调房间密闭一定要好,使用时窗户要关严,以保持冷气不流失;室内人员进出最好不要过于频繁;如房间光照太强,白天可拉上窗帘,挡住一部分热量。有人怕使用空调时间长费电,认为开一会儿关一会儿才省电。恰恰相反,空调在启动时高频运转瞬间电流较大,频繁开关最耗电,且损耗压缩机,因此不要用频繁开关来调节室温。

  4、怎样才是正确使用中央空调?

  专家提醒,正确的使用方法是:设定室温时,不要与室外温差太大,如室外30℃,室内设定25℃就可以了,达到25℃后,如觉得不凉,可再将设定温度下调几摄氏度,这样空调高频运转时间短,可节电。空调运行过程中,如觉得太凉,无需关闭,只要将设定温度调高即可
