Core Tech: Difference at the Core – Refrigerators

Core Tech, the heart and soul of all LG Home Appliances,

is created through innovative technologies.


At our products' core, performance-defining innovation lies in the technologies of Inverter Linear Compressor™ in refrigerators, Inverter DirectDrive™ in washing machines, and DUAL Inverter Compressor™ in air conditioners.


It's not just about the essential tech and components.

It's what LG is committed to, unwaveringly, for our customers,

It's what we've built from the ground up to set ourselves apart from others.

It's what has earned the trust of our customers over the years.


Now, as we all shape towards sustainable lifestyles,

LG Core Tech, too, evolves with us.


Core Tech is the foundation of our technology representing

our perspectives and philosophy,

and dedicated to culture tech that will create a better environment for all.

Washing machine, refrigerator, and air conditioner come with each key component.

LG Inverter Linear Compressor™, powering refrigeration innovation

The compressor is the beating heart of a refrigerator, circulating refrigerant to produce cold air and deliver differentiated performance and reliability. LG's Inverter Linear Compressor™ delivers motor force to the piston in a straight line without rotating, compressing it to increase energy efficiency. With inverter control for precise motor speeds, LG's compressor technology, first pioneered in 1993, has been powering refrigerators since 2001. The Inverter Linear Compressor™ exemplifies how LG is leading the global refrigerator market based on differentiated core technologies.

Energy efficiency

Year-round energy efficiency and savings

Want to smile over your electricity bill?

LG Inverter Linear Compressor™ pistons move in a straight motion rather than rotating, enabling direct power transfer for 32% more efficiency than constant speed compressors.

One point of friction, high energy efficiency

The LG Inverter Linear Compressor™ delivers motor force to drive the piston in a straight line rather than rotating, improving energy efficiency.

Durable design for lasting performance

Is there a refrigerator that can provide 10 years of peace of mind?

LG's Inverter Linear Compressor™ is durable with fewer moving parts and fewer places for friction and wear. It comes backed by a 10-year warranty, so you can focus on making memories instead of repairs.

Ultimate freshness, preserving the natural goodness of your food

Want to enjoy just-picked freshness all week long?

Take control of temperature fluctuations with LinearCooling™, allowing your refrigerator to keep your favorite food and drinks fresh for longer. Enjoy tastier meals with groceries that retain their freshness.

Keep food fresh for up to 7 days

LinearCooling™ maintains relatively precise inner temperatures within ±0.5℃ over time by circulating cold air more frequently than conventional cooling systems. LG's strategically placed sensor also helps maintain your desired temperature.

A quiet fridge for quality time

Want a quieter kitchen for more enjoyable dinner conversations?

The source of a refrigerator's noise is the compressor. The Inverter Linear Compressor™ has fewer friction points, so it is smoother when starting and stopping. During this quiet operation, you can chat without any distracting refrigerator noises.
