LG Electronics (LG) said it has sold 15 million refrigerators worldwide powered by its proprietary Inverter Linear Compressor, the appliance division’s core technology.
Sales of LG premium refrigerators rose 8 per cent last year compared to the previous year. LG expects to sell 4 million more units this year, an average of seven refrigerators sold every minute.
LG’s Inverter Linear Compressor is a critical component of its premium refrigerator and is considered a core technology behind the company’s appliances. Unlike conventional rotary compressors that utilise circular motion, LG’s Linear Compressor converts linear motion into cooling power, reducing energy consumption and noise level compared to refrigerators with conventional motors.
LG said its fifth-generation Inverter Linear Compressor, introduced in 2014, delivers 55 per cent better energy efficiency and 15 per cent less noise compared its first-generation compressor. The company said it currently holds 981 patents in South Korea for its Linear Inverter Compressor technology, as well as 232 patents in the United States and 52 across Europe.
LG expanded its award-winning line-up last year with its new Centum System refrigerator developed specifically for the European market.
“Our commitment to developing core technologies such as the Inverter Linear Compressor is a key element of the success of LG refrigerators all over the world,” said Song Dae-hyun, president of LG’s and Home Appliance & Air Solutions Company. “Our priority to enhance refrigerator performance, reduce noise levels while using less energy is how we continue to bring value to our customers.”
