Since the middle and late June, many parts of the country have seen continuous high temperature. According to the statistics of the National Meteorological Center, the average temperature in June is 22.1℃, 0.9℃ higher than that in the same period of the year, which is the highest in history since 1961.
Today, the central meteorological station continues to issue high temperature orange alert: it is expected that during the day of July 28, most of the southern part of China and along the northern Tianshan Mountains and southern Xinjiang basin, western Inner Mongolia and other places will still have high temperature weather above 35℃. The highest temperature in parts of central Zhejiang, central Jiangxi, southern Xinjiang Basin and Turpan can reach more than 40℃.
The hot weather in recent days has made many people call it "hot" and say they cannot sleep without air conditioning at night. Recently, a picture with Gree's logo has been circulated on the Internet, drawing public attention to the use of high-temperature air conditioners.
Will the air conditioner "break down" when the temperature is too high? Gree: That's not true
According to the poster circulating on the network, the temperature will be above 39℃ in the next week, all air conditioners will reach the critical point of design operation range (normal operation range +43℃), the current outdoor temperature ground has exceeded 60 degrees, far beyond the normal application range of air conditioning, the effect of air conditioning will be worse and worse, and even outdoor unit thermal protection shutdown.
In this regard, Gree Electric Appliances (hereinafter referred to as "Gree") responded that: this is false news, Gree air conditioning high temperature resistance performance is good, the current after-sales contact with the refrigeration problem is not much. So even if the outdoor ground temperature has exceeded 60 degrees, Gree air conditioning products are still in the normal operating range.
A Gree staff member said, "This picture has been circulating for many years and can no longer be traced back to its source. "
It is understood that the normal operating temperature range of air conditioning is -7℃ to 43℃. In the case of high temperature does not retreat, the compressor will overheat protection, which is the normal phenomenon caused by the design principle of air conditioning, not the performance of air conditioning failure.
With advances in refrigeration technology, today's air conditioners can operate even beyond that range. Besides Gree, Midea, Haier and other brands also claim that their air conditioners can operate stably at a high temperature of 60℃.
"I am the chairman of the Compressor Sub-committee of the International Refrigeration Committee," Dong Mingzhu, chairwoman of Gree Electric Appliances, said in a live broadcast on July 26. "We set international standards, so Gree air conditioners should have higher requirements for quality. Our products have more than 500 million users in the global market, and these consumers can experience Gree's quality even more."
She also showed wind blades of different materials during the live broadcast. "By comparison, the colored blades cracked and shattered after about 3,500 rotations, and Gree's blades are still intact. This is also Gree's standard. Our raw materials are ten thousand pieces/ton, the colored one is more than two thousand pieces. Assuming a 10-year service life, 5 blades need to be replaced during the period, costing nearly 1000 pieces. Choose Gree air conditioning 10 years free repair, this cost will give you save. I think companies should think about how to be responsible to consumers in this process." She said.
These qualities come from the enterprise's pursuit of technological innovation. According to data provided by Gree, up to now, the company has 16 research institutes, 16,000 R&D personnel and 35 "internationally leading" technologies.
Master the core technology, also master the market. According to data released by Euromonitor International, a market research agency, Gree home air conditioners took up 20.2% of the global market share in 2021, and the brand's retail sales once again ranked first in the world. So far, the market share of Gree household air conditioners has been the first in the world for 17 consecutive years.
