LG Electronics announced the sale of its 15th million refrigerator worldwide powered by its proprietary Inverter Linear Compressor, the appliance division’s most successful core technology. LG saw that the sales of its premium refrigerators increased 8 percent last year compared to the previous year and expects to sell four million more units this year. “Unlike conventional rotary compressors that utilize circular motion, LG’s Linear Compressor converts linear motion into cooling power much more efficiently – the company explains -. This process reduces energy consumption and noise level compared to refrigerators with conventional motors”. Since developing the Inverter Linear Compressor 16 years ago, LG has continuously worked to improve its technology. LG’s fifth generation Inverter Linear Compressor, introduced in 2014, delivers 55 percent better energy efficiency and 15 percent less noise compared its first generation compressor. LG 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.
