An inverter propane (R290) compressor can reduce the energy consumption of vending machines by up to 27% compared to a fixed-speed compressor, according to research conducted by Embraco, a Brazilian manufacturer and brand of Nidec Global Appliance.
The inverter technology, also known as a variable-speed compressor, saves energy by adjusting the device’s operation speed to meet the requirements of the refrigeration equipment rather than running at a single speed regardless of demand.
The case study, which focused on the Asian market, was presented by Xu Bo, Sales Manager for Southeast Asia at Embraco, during the State of the Industry session at the ATMOsphere APAC Summit 2022. The conference, which took place June 27–28 in Tokyo, was organized by ATMOsphere, publisher of Hydrocarbons21.com.
According to Xu Bo’s presentation, the study was conducted to “evaluate alternative solutions to reduce the energy consumption for the vending machine and apply [a hydrocarbon] solution to comply with regional requirements.”
