四类新家电将看好变频空调器传统空调器是通过压缩机的启停来控制室温，室温波动较大。采用变频控制的空调器系用脉宽调制（ＰＷＭ）方式，通过变频器，改变供给压缩机的供电电源频率，进而改变压缩机转速，调解空调器的制冷或制热量。制冷时，根据由室温传感器测出的室温... Four types of new appliances will be optimistic about the inverter air conditioner air conditioner traditional start and stop to control the compressor room temperature, room temperature fluctuations. The air conditioner with frequency conversion control uses the pulse width modulation (PWM) mode to change the frequency of the power supply to the compressor through the inverter so as to change the compressor speed and adjust the cooling or heating capacity of the air conditioner. When cooling, according to room temperature sensor measured by room temperature ...
