LG expands global rollout of energy-efficient Inverter Scroll Chiller with R32 refrigerant

LG Electronics is expanding the global availability of its air-cooled Inverter Scroll Chiller, a high-efficiency HVAC solution designed to meet growing demands for sustainability. The advanced system features R32 refrigerant, which has approximately 70 percent lower Global Warming Potential (GWP) than the widely used R410A.

As an inverter-driven heat pump system, the chiller can supply both chilled and hot water, making it ideal for year-round use in mid-sized commercial buildings such as hotels, hospitals, schools, and office spaces.

Advanced energy efficiency and reliable performance

The Inverter Scroll Chiller is powered by LG’s All-Inverter compressor, which operates between 30Hz and 120Hz for consistent performance even under partial load. Efficiency is further improved by LG’s patented HiPOR™ (High Pressure Oil Return) system that reduces energy loss by directly returning oil into the compression chamber.

The unit achieves an Integrated Part Load Value (IPLV) of up to 5.9. Heat exchangers support a wide water outlet temperature range—from -10°C to 60°C—accommodating a variety of thermal applications.

Reliability is also central to the system’s design. With twin All-Inverter compressors, vapor injection technology, and a refrigerant-cooled heat sink, the chiller can operate in outdoor temperatures up to 52°C or as low as 20 percent capacity during extreme cold. Additional features include compressor backup, sequential defrost, and hot water output up to 60°C to help prevent Legionella growth in healthcare or spa settings. LG’s Black Fin coating also enhances durability in humid or coastal environments.

Smart control systems for flexible integration

LG offers a multi-tiered control ecosystem for different project sizes:

• Small-scale installations can use an intuitive 5-inch HMI touchscreen, with remote access up to 500 meters.

• Mid-sized systems benefit from ACP and AC Smart controllers, which support up to 10 chillers with error tracking and scheduling.

• Large-scale operations can integrate with LG’s BECON (Building Energy Control) platform, which can manage up to 30 chillers and multiple auxiliary devices.

Energy-saving algorithms reduce power consumption by up to 10 percent. In case of a power failure, auto-recovery quickly restores previous settings. The unit’s silent mode reduces its 68dB operating noise during off-peak hours.

Following initial launches in North America, Europe, and South Korea, LG is expanding availability globally in 2025. One successful installation at Garden Grove Elementary School in Winter Haven, Florida, replaced a 60-ton unit with three Inverter Scroll Chillers. The school reported an 18 percent drop in energy consumption and quieter HVAC performance, enhancing the surrounding learning environment.

“LG’s latest Inverter Scroll Chiller is designed to deliver high energy efficiency and flexible system management, allowing customers to meet real-world HVAC demands with confidence,” said James Lee, president of the LG ES Company.
