The deep winter has arrived, and whether the heat pump can operate stably in the severe cold is undoubtedly the most concerning issue for users. However, the tests go far beyond this. In northern or coastal areas, what is even more worrying is: can the outdoor unit remain durable year after year in the wind, frost, rain and snow? After all, substances like de-icing agents and salt fog are "invisible enemies" that can significantly shorten the lifespan of a device that is supposed to last for ten years or more.
In response to this issue, during the recent extreme cold challenge that the industry has been focusing on, Haier Smart Building Heat Pumps have provided a positive response: Not only does it perform stably at -40℃ ultra-low temperatures, but the excellent corrosion resistance of the product has also been verified under harsh conditions, achieving a 4-fold improvement. This is attributed to Haier Smart Building's meticulous R&D system and manufacturing capabilities, as well as the confidence it has in launching the industry-leading 6-year warranty.
In order to overcome the durability problem of heat pumps in extreme environments, the R&D team of Haier Smart Buildings sent the products to a more rigorous "extreme examination room" than the real world. In the laboratory, the outdoor unit of the heat pump underwent more than 2,000 hours of intensified salt spray corrosion testing to verify its reliability for long-term use. Eventually, this meticulous refinement enhanced the anti-corrosion ability by four times. But this was not enough. The team also directly took the machines to the extremely cold regions of Mohe and the snowy mountains of Changbai Mountain for on-site tests. In Mohe, the unit operated quietly at -40°C, keeping the indoor temperature warm as if it were spring. In the snow-covered mountains of Changbai Mountain, the unit achieved rapid defrosting in 5 minutes and produced 55°C hot water in 2 hours. These rigorous tests were ultimately aimed at addressing the concerns of users, allowing them to feel at ease with heating every winter.
Behind this technical strength and product performance lies Haier's profound R&D system for intelligent buildings. Leveraging 7 global R&D centers, the world's first smart factory, and a laboratory cluster in 50 countries, the team not only achieved self-production of key components and automated production, but also completed 200 process tests and various simulation scenarios such as snow and sun exposure before the products were introduced to the real environment. At the same time, by leveraging the large model in the HVAC vertical field and the AI selection system, Haier's intelligent buildings integrate digitalization throughout the entire manufacturing process, shortening the R&D cycle by 20%, improving design efficiency by 30%, and achieving full control from experimental verification to scene delivery.
Looking at the development of Haier's smart buildings, every technological breakthrough is based on the actual needs of users. From 2000 hours of corrosion tests, over 200 strict process inspections in the laboratory, to multi-scenario field verifications, the company has always integrated users' real needs and quality assurance throughout the entire product manufacturing process. It is this user-centric R&D concept that has enabled Haier's full range of heat pump products to gain widespread trust in the market and maintain the top position in the industry for five consecutive years.
