Inverter technology changes motor and compressor speeds freely. Just like the "natural breeze" function on fans, inverter technology allows a fan to go faster for a moment, and then slow down the next moment. Inverters change the power provided to a compressor and motor through voltage and frequency to switch their speeds at any time. This enables both powerful output and delicate control, making it possible to spend the minimum amount of energy necessary for the operation without any waste. Inverter technology is also quieter and more energy efficient than traditional HVAC products.
