Home Multi V Heat Pump

MULTI V HEAT PUMP

MULTI V series offers outstanding energy savings, easy installation and connection to many different types of indoor units, making it easy to design.


World’s First Class, Rated and Part Load Efficiency


LG’s 4th Generation Inverter Compressor

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.




World’s First Class, Rated and Part Load Efficiency

* Comparison between 20HP in cooling mode
* Comparison between 20HP in cooling mode, part load efficiency based on internal test data




HiPOR™ (High Pressure Oil Return)

HiPORTM technology enables oil to return directly into the compressor, instead of returning through the refrigerant suction pipe, to minimize energy losses




Vapor Injection

Vapor Injection uses a two-stage compression effect, which is designed to provide efficient heating in extremely cold environments. Combined with HiPORTM, this system boosts heating performance and enhances heating temperature range.




Active Refrigerant Control

Active Refrigerant Control automatically controls the level of refrigerant amount to maximize efficiency.




Variable Heat Exchanger Circuit

Variable Heat Exchanger Circuit is the world first technology which intelligently selects the optimal path for both heating and cooling.




Flexible Capacity Control

It is possible for the user to control heating & cooling performance and save energy through outdoor capacity control. - 5 Basic steps capacity control - 10 steps control is possible with IO(Input & Output) module (option) - Up to 40% input power reduction through energy saving operation





Easy Design with the Most Convenient Features


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 designer’s work time and providing more efficient design.




Light Weight Outdoor Units

30% lighter weight than major competitors





Always Ahead of the Competition and on the Leading Edge of Innovation with Powerful Heating and Unsurpassed Cooling Performance.


Fast Heating and Cooling via Advanced Inverter

In conventional models, inverter compressor and on/off compressor operate one by one, which taking far longer to reach maximum capacity. Thanks to LG’s all inverter compressor system and high performance cycle design, MULTI V IV delivers fast cooling or heating by operating two compressors simultaneously.




Continuous Heating Operation in Defrost

MULTI V IV uses the split-defrost technology for continuous heating operation, which provides consistent heating for the indoor environment to improve both heating capacity and indoor comfort. * Continuous heating operation can be switched to existing defrost mode depending on environmental conditions.




Cooling Operation Range Down to –10°C (14°F)

LG has expanded the temperature range for continuous cooling from -5°C (23°F) to -10°C (14°F) to provide a better solution for zones that require four seasons cooling such as server rooms.




Wide Operation Range

MULTI V IV extended range of continuous cooling and heating operation through enhanced inverter compressor and control technology.



Easy and Reliable, LG Introduces the Self-regulating Heating and Air Conditioning System.


Upgraded FDD (Fault Detection & Diagnosis)

Newly upgraded FDD elements provide the optimal solution for user reliability and easy maintenance.




Auto Refrigerant Collection

In case of an indoor or outdoor unit replacement for service, refrigerant from the malfunctioning unit is transferred to the outdoor unit by pumping down or to an indoor unit by pumping out for easy service.




Smartphone Monitoring & Control




Auto Compressor Oil Management

Compressor reliability is improved with a oil level sensor that allows for oil balancing and oil return.
