LG’s 4th Generation Inverter Compressor
With a fourth generation inverter compressor, the Multi V IV boasts top-class energy efficiency.
Two-stage compression improves heating efficiency and boosts heating performance even in extremely cold weather (up to -25°C).
Extended Compressor Speed 15~150Hz
Multi V IV compressor elaborately adjusts its speed in respond to required temperature, thus reducing energy loss while providing comfort in a short period of time.
LG’s HIPOR™ (High Pressure Oil Return)
LG’s HIPOR™ technology resolves compressor efficiency loss and improves part load efficiency by directly collecting oil to the inside of the compressor.
Smart Oil Return
Oil level sensor checks and optimizes compressor oil level in real time, thus enhancing compressor reliability and heating performance.
Optimal Heat Exchanger Circuit
Variable Heat Exchanger Circuit intelligently selects the optimal number of heat exchanging paths to increase efficiency.
Smart Load Control
It adjusts indoor discharge air according to outdoor and indoor temperature. This optimizies energy efficiency and maximizes indoor comfort level in cooling/heating modes.
Wide Operation Range
Multi V IV has extended the range of cooling and heating operation through enhanced inverter compressor and control technology.
Continuous Heating in Defrosting Operation
Multi V IV’s advanced defrosting technology provides consistent heating in cold weather.
By adjusting refrigerant flow, Multi V IV maintains comfort indoor environment once it reaches the target temperature.
Upgraded Fault Detection & Diagnosis (FDD)
The whole new FDD quickly diagnoses system errors and provides optimal solution for maintenance.
Expanded Piping Capabilities
Multi V IV boasts long piping capabilities. 1000 meters in total piping length (longest piping length between outdoor & indoor unit is 200 meters).
Lightweight Outdoor Units
Multi V IV is easy to handle and install due to lightweight outdoor units.
Multi V IV’s larger capacity unit significantly saves valuable building space.
