Inverter and non-Inverter Air Con., What is the difference?

Someone know only one topic about the difference between Inverter AC and non-Inverter (or Fix speed) AC, it's power consumption.
It's not easy to explain how Invert and non-Inverter AC work. This video I try to show you what it is. Hope it can help you to under Invert air conditioner or fridge/freezer.
