Inverter compressors show 1 year payback in vending machines, in new Embraco case study

The expanding vending machines market in China and Southeastern Asia, due to the 2021 recovery after the Covid-19 pandemic requiring unmanned retail, increases the need for these kinds of appliances to become ever more energy efficient, in order to reduce their life cycle cost, as well as have a lower environmental impact. To meet these new demands new compressors technologies are needed, such as variable speed, also known as inverter technology, and natural refrigerants. In a recent case study, Embraco, global provider of refrigeration technology for the complete residential and commercial cold chain and a Nidec Global Appliance’s brand, reached 27% energy savings in a vending machine using a variable speed compressor to replace a traditional fixed speed one.
