A:Answer Thanks for your interest. The Digital Inverter Compressor operates at variable speeds based on demand which helps to save energy since it works only has hard as it needs to. For example, if the door is opened frequently or warm food is placed inside, the compressor motor will run at higher RPMs to meet the cooling demand. On the other hand, it will run at a lower RPM during times when the need is not as great, such as overnight, or during the day when no one's opening the door.
