The document discusses trends in refrigerants and energy efficiency for light commercial refrigeration equipment. It notes that hydrocarbons are becoming the main choice for plug-in commercial cabinets due to regulations phasing out hydrofluorocarbons. Some barriers to the adoption of hydrocarbon technology include the 150 gram charge limit, training requirements, and safety standard limits. The document presents Embraco's hydrocarbon compressor product ranges that meet the 150 gram charge limit for cabinets. It also discusses Embraco's new inverter compressor technologies for various refrigerants that provide increased energy efficiency and cost savings over traditional compressor types.

Propane can be considered as most sustainable
refrigerant for light commercial segment because of
both, direct and indirect emissions
R290 offers an excellent option to meet F-Gases
regulations and energy standards.
With 150g of propane charge it’s possible to cover
most of unitary, plug-in applications
An international effort to increase HC charge limit
in -89 standard to cover all plug in range with
single circuit solution is in progress
