In recent days, “aluminium copper” has once again become a popular topic in the domestic electricity industry. On the occasion of the announcement by the various air conditioners giants of their accession to the convention on self-regulation of the working group on aluminium-consolidated applications of air conditioning, the chairman of the board of directors of grei electrics, dong myung joo, made a clear statement not to use “aluminium copper” and “aluminium has not yet met the same technical conditions and safeguards as copper”. Dong ming ju said, “we didn't say no, we did, until aluminium was able to replace copper completely, and i would go on.”
Behind the firmness of the industry that insists on “real copper” is the quality promise that glig has made for decades. Growing from air conditioners to a diversified, technology-based global industrial manufacturing group, gwi has over the years continued to innovate in advanced core technologies, leading to higher thresholds for technology upgrading. From the world's premier compressor that has broken -35°c ultra-low-temperature heat limit to the cold-winded "cool king" air conditioner that can also be delivered on the firehill limit hot soil, glugs have been on the road to exploring technology for "ceiling". So far, gwig has accumulated over 130,000 patents and 50 international leading technologies。
In the area of energy efficiency reduction, in 2024, glig introduced the world's largest 1300 tonnes of magnetic suspension compressor, which is equivalent to six of the traditional european and american brands, and achieved 100 per cent self-study and 100 per cent self-manufacturing of key technologies in large central air conditioning。
At the beginning of 2026, the good news was rebroadcast that gwidth had been awarded the china energy conservation association's principal award for the scientific and technological progress of energy saving and reducing emissions for 2025, under the project “a wide area-based, multi-line, high-impact, key technologies and applications”。
In keeping with its technical orientation, gwice also works to promote industry standards. Compressors are the “heart” of air-conditioning. China's refrigeration compressors, which had previously accounted for 82 per cent of the world's total, have dominated the market, yet internationally standardized discourse is still held by western countries. It was not until the end of 2020 that the new international standard-setting for cooling compressors was put on the agenda by dong myung joo, who successfully hanged iso/tc 86/sc 4 (international organization for standardization/technology committee for refrigeration and air conditioning/sub-committee for testing and assessment of refrigeration compressors)。
In june 2025, two iso international standards for refrigeration compressors, iso 18501, a volume compressor performance evaluation, and iso 18483, a centrifuge compressor performance evaluation, were officially released and introduced globally. This is the global area of refrigeration compressors. For the first time, chinese enterprises broke the western monopoly on standard-setting and achieved a historic leap from “products going to sea” to “standard going to sea”。
Hard power casts hard mass. "quality is about two lives, one of consumers and one of businesses. Market recognition and trust can only be truly achieved by building a better life for consumers with quality products. "to pursue perfect quality and to apply it in the spirit of gwig's enterprise. It is understood that a gac requires 8,000 mass inspectors and 862 quality testing procedures to get out of the plant. It was indicated that, under extremely high quality control, the failure rate for gac had been reduced to three per 10,000 air conditioners for each sale, with only three units requiring maintenance. This was also the bottom line for gwig's initiative in 2021 to introduce a 10-year free package。
“ten years free of charge” is the longest period to date promised by the national air-conditioning industry and is consistent with the safe use of domestic electricity, meaning that glig provides users with security covering the entire life cycle of the product. In contrast, a six-year warranty policy is still prevalent in industry. An air conditioner is estimated to cost an average of 400-600 yuan during the 6th to 10th year of operation, while a gwig user is able to achieve the “zero cost” of the expenditure。
From the “obstinacy” of “real copper” to the development of international standards; from the 862 critical points on the production line to the 10-year consumer-oriented bargain, tung myung-ju's groove has been practising a “permanentism” of manufacturing。
