The new High-Side Shell (HSS) scroll inverter compressor and BLDC concentration motor coil optimizes part load efficiency,

with the 50% reduction in weight and increase in high-frequency operation of 120Hz to 150Hz.

LGs 4thGeneration Inverter Compressor

*Operation available up to 160 Hz dependent upon operating conditions

Vapor Injection- Maximize heating capacity via two-stage compression

- Provide powerful heating in low temperature conditions

- Improve energy efficiency and heating performance

Extended Compressor Speed 150Hz- Rapid operation response

- Capable of reaching required temperature quickly

- Increase part load efficiency

HiPORTM(High Pressure Oil Return)- Resolve compressor efficiency loss caused by oil return

- Improve part load efficiency at all operation ranges

Smart Oil Return- Oil level detection in real time

- Oil recovery occurs only when required

- Enhance user comfortb

Expanded Piping Capabilities

MULTI V IV inverter technology and subcooling control circuit technology allows greater piping length and outstanding

elevation differences. A cooling system can be implemented more flexibly in a high-rise building or complex facilities,

reducing the designers work time and providing more efficient design.
