Embraco’s propane-based variable-speed compressor has reduced the energy consumption of vending machines in the Asian market by up to 27%.
Vending machines using hydrocarbons cannot be placed near exits under ASHRAE/UL rules.
Among the companies exhibiting at Venditalia, there was not yet a clear trend towards adopting CO2 or hydrocarbons as the natural refrigerant of choice.
Polarpure R290 is a natural refrigerant with a sustainable CO2 footprint, manufactured by GTS through its distillation plant using R290 heat pumps and powered by a 1MW solar plant. Polarpure R290 is most widely used in heat pumps, air conditioning systems, dryers, commercial freezers and refrigerators, ice cube machines, bottle coolers, vending machines and cascade refrigeration systems. It is the best ecological alternative to environmentally harmful R134a.
Sanden Vendo presented the DV9, a new propane-based vending machine, at Venditalia last week.
After establishing that carbon dioxide would be its standard refrigerant for new beverage coolers, vending machines and fountain equipment, the Coca-Cola Company “will open the door” to hydrocarbon refrigerants for smaller cooler equipment, said Antoine Azar, the company’s global programme director.
Oscartielle, Panasonic and Epta were among the many companies showcasing plug-in propane-based refrigerated lockers for supermarkets at EuroShop 2023.
The larger fittings would be suitable for bigger VRF systems.
All high-efficiency refrigeration and freezing appliances – and a clothes dryer – use either R290 or R600a.
