What is the Inverter technology in air conditioners?

The Inverter technology (DC) is the latest evolution of technology concerning the electro motors of the compressors. An Inverter is used to control the speed of the compressor motor, so as to continuously regulate the temperature. The DC Inverter units have a variable-frequency drive that comprises an adjustable electrical inverter to control the speed of the electromotor, which means the compressor and the cooling / heating output. The drive converts the incoming AC current to DC and then through a modulation in an electrical inverter produces current of desired frequency. A microcontroller can sample each ambient air temperature and adjust accordingly the speed of the compressor. Inverter air conditioning units can offer improved energy efficiency compared to traditional fixed-speed units, while adjusting compressor output according to heating or cooling demand. Inverter air conditioning units may have a higher initial purchase cost than fixed-speed models. Their energy-efficient operation can help reduce electricity consumption, depending on usage patterns, operating conditions and the models being compared.
