变频空调理所当然的成为我们考虑的首选对象。变频空调的压缩机没有频繁的启停现象，定频空调则通过启停压缩机控制制冷、制热量。启动时的耗电极大，所以定频空调耗电比变频空调大；变频空调还可以根据房间的需要调节输出的冷、热量，而定频空调只能以最大的能力输出，对能源造成浪费。

可变频空调中也有优劣，我们又如何选购变频空调呢？以下介绍几个选购的关键因素：

Variable frequency air conditioning also have good and bad, how can we buy inverter air conditioner? The following describes several key factors to choose:

　　1、先进的直流变速技术。 直流变速空调使用更舒适，节能性更好。

1, advanced DC transmission technology. DC variable speed air conditioning the use of more comfortable, better energy saving.

　　2、先进节能的压缩机。压缩机是空调机的核心，压缩机的性能直接影响到空调机整机的性能。

2, advanced energy-saving compressor. Compressor is the core of air conditioner, compressor performance directly affects the performance of the air conditioning machine.

　　3、电子膨胀阀。为了精确控制冷媒流量，提高节能性和温度控制精度，电子膨胀阀是必需的部件，采用电子膨胀阀的空调机能更好的根据负荷的变化进行能力调整。

3, the electronic expansion valve. In order to accurately control the refrigerant flow, improve energy efficiency and the precision of temperature control, electronic expansion valve is a necessary component of electronic expansion valve, the air conditioner can better according to the change of load capacity adjustment.

　　4、高效的换热器：空调机的热交换器的换热效率对空调的节能性有很大影响，作为一台优秀的节能空调，必须要有高效的热交换器。

Heat exchanger: 4, efficient heat exchanger of air conditioner heat transfer efficiency has a great influence on air conditioning energy saving, as a good energy-saving air-conditioning, there must be heat exchanger efficiency.

　　5、变频控制板：变频控制板的运算速度及控制精度对机器的运转效率也有较大影响。

5, the frequency conversion control panel: efficiency, speed and control precision of frequency control board has a great influence on the machine.

　　6、风扇电机：室外机风扇电机是空调机中除压缩机外的耗电大户。真正的节能空调必须对风扇电机也采用变速控制。

6, the fan motor: outdoor fan motor is the power consumption in addition to outside the compressor of air conditioner. Energy saving air-conditioning really must also shift control the fan motor.
