上海春普为大家讲解下是如何选购变频空调

优点:低电压启动,紧缩机低频启动,对电网无冲击,电压不是过低,空调能够远转。低温制热,依据设定温度与室内温度的差值大小,来改动紧缩机的运转速度,从而改动能量输出,进步制热性能。宁静运转,紧缩机运转时震动较小,所以室外机运转噪音小。缺陷:耐电压冲击性能差,变频空调不怕电压低,怕电压不稳,电压频繁动摇容易损坏功率模块,是如今变频空调通病和多发病。变频空调较定频空调电控系统原理构造复杂,修复周期长。服务费用高,损坏部件可修复性差,无故抬高了费用。件替代性差,若厂家无件,机器只得报废。

Advantages: Low voltage startup, low frequency startup of compressor, no impact on power grid, voltage is not too low, air conditioning can rotate far. Low temperature heating, according to the difference between the set temperature and the indoor temperature, to change the speed of the compressor, thereby changing the energy output, improve the heating performance. Running quietly, the vibration of the compressor is small, so the noise of the outdoor machine is small. Defects: poor voltage impact resistance, frequency conversion air conditioning is not afraid of low voltage, voltage instability, frequent voltage fluctuation is easy to damage power module, is now common and frequently occurring frequency conversion air conditioning. The principle of frequency conversion air conditioning system is more complex than that of constant frequency air conditioning electronic control system, and the repair cycle is longer. Maintenance costs are high, the repairability of damaged parts is poor, and the cost is raised without reason. If the manufacturer has no spare parts, the machine will have to be scrapped.

原理:单相交流市电1PHAV220V,经过整流、滤波变直流电DC310V,经过功率模块直流电DC310V,变三相可变交流电3PHAC0-172V。依据设定温度与室内温度的差值大小,改动三相交流电的输出电压,控制紧缩机的运转速度。区别:定频空调,紧缩机运转速度恒定,能量输出没有变化。电压、效果、噪音等方面略胜一筹。变频空调,依据设定温度与室内温度的差值大小,改动紧缩机的运转速度,是动摇的,能量输出可变,效果能够人为改动。

Principle: Single-phase AC power 1PHAV220V, DC 310V through rectification and filtering, DC 310V through power module, and variable three-phase AC 3PHAC0-172V. According to the difference between the set temperature and the indoor temperature, the output voltage of three-phase alternating current is changed to control the running speed of the compressor. Differentiation: Fixed frequency air conditioning, constant speed of compressor operation, no change in energy output. Voltage, effect and noise are slightly better than others. Frequency conversion air conditioning, according to the difference between the set temperature and the indoor temperature, changes the speed of the compressor, is shaky, the energy output is variable, the effect can be artificially changed.
