Siemens and Bosch are from the same school, but their popularity and sales are far superior to Bosch's. In the Chinese market, the sales of Siemens refrigerators basically remained in the top three, the largest among foreign brands.
 
The Siemens refrigerator and Bosch refrigerator on the market are both from BSH, and they are almost the same in terms of origin, technology, materials, functions and market channels, and many refrigerator models can be found in the same model in both brands. In contrast, Bosch products are more mid-to-high-end, and flagship models always come out of Bosch refrigerators first, and then Siemens refrigerators.
 
Freshness and hydration
 
Siemens also proposed the concept of "zero-degree vitamin preservation", which is similar in essence to Panasonic's micro-freezing technology, allowing food to be stored in a state of frozen but not frozen, and finding a new balance between loss of nutrients in freezing and inability to withstand storage in refrigeration. This preservation zone can be subdivided into a high-humidity zone for vegetables and fruits and a low-humidity zone for meat.
 
The high humidity zone is not achieved by actively adding water, but by minimizing water loss. Siemens has added a filter membrane to the cabin to allow the cold air circulating by air cooling to pass through, but prevent water vapor from entering and leaving, which can increase the relative humidity in the cabin to 90%, which is more conducive to the storage of fruits and vegetables.
 
Alarm function for not closing the door
 
Forgetting to close the refrigerator or not closing it tightly can cause a lot of loss of electricity bills and affect the preservation of food, and Siemens has caused a lot of criticism because of these obvious design flaws. In response to this everyday detail, Siemens has now launched an unclosed door alarm function, which will sound a ticking alarm to remind the door to close if the refrigerator door is not closed tightly for more than 1 minute. Most Siemens refrigerators come with this feature. Even in order to save the reminder, some Siemens 10,000-yuan products have launched an auxiliary door closing system, which automatically closes the door to avoid the situation of false door covering.
 
Mixing and after-sales service
 
Siemens has a handful of direct-cooled refrigerators, partially air-cooled and more than half mixed-cooler refrigerators, which are unique among all brands. Japanese and Korean refrigerators are all air-cooled refrigerators, and domestic brands are mostly low-end direct cooling, mid-to-high-end air-cooling, and there are no hybrid refrigeration products. Mixed cooling refrigerators can give full play to the advantages of air-cooled without frosting and direct cooling without blow-drying.
 
Compared with Japanese and Korean brands, Siemens' mid-range products are more cost-effective, especially the 4,000-7,000 yuan mixed cooling multi-cycle refrigerator. Among the flagship products, Siemens' top technology is slightly thin, not as powerful as Japan and South Korea, and even Haier. Siemens' after-sales and maintenance network is perfect, which is generally higher than that of Japanese and Korean brands. The warranty time of the refrigerator is 1 year for the whole machine and 3 years for the main components.
