An inverter controls the speed of the motor powering the compressor in an HVAC system. Without an inverter, a compressor motor only runs at 100% or 0% power, which is very inefficient. An inverter compressor can run continuously variable speeds depending on the varying workloads required throughout the day. As an inverter only runs at the capacity that is necessary, it is able to reduce the energy consumption of an air conditioner by as much as 40% and, thus, produces a more efficient SEER (Seasonal Energy Efficiency Ratio). The LG Smart Inverter delivers more efficient operation of HVAC systems and ensures a more dependable product.
