After years of development, the refrigeration theory and technology of refrigerators have become mature, and it is difficult to improve. In order to avoid disorderly competition, manufacturers with high brand awareness and large scale have been maintaining high R & D, trying to occupy market share through new products and improve their profitability. Manufacturers mainly update and upgrade existing refrigerators in terms of function, performance, appearance, etc., and at the same time develop in the direction of multi-function, intelligence, energy saving and environmental protection.
In particular, it is worth noting that intelligence has become one of the main pursuits of consumers for refrigerators. The release of the smart home index and the promotion of the smart home concept indicate that smart home appliances will gradually enter life. With the maturity of chip and network solutions, it is expected that smart refrigerator products will usher in rapid development in the future.
Home appliance glassThe technical level and characteristics
The core technology of the home appliance glass industry focuses on deep processing and overall manufacturing processes. Among them, it is usually a customized product, and its technical level is mainly reflected in the design, manufacturing and integration of the overall product. In the application process of end products, it is mainly reflected in various performance indicators such as heat insulation, heat preservation and emissivity. At present, the deep processing and manufacturing technology of home appliance glass has been relatively mature.
The main indicator to measure the insulation performance of hollow home appliance glass is the K coefficient. K is the heat transfer coefficient of the material, which is used to express the thermal insulation performance of the material. The larger the K value, the more heat is transferred and the worse the thermal insulation performance. The smaller the k value, the less heat transfer and the better the thermal insulation performance. The thermal conductivity of home appliance glass is about half lower than that of single-layer glass, which is mainly due to the effect of gas barrier. Due to the low thermal conductivity of the gas, the thermal insulation performance of the insulating glass is improved.
Home appliance glassWith outstanding heat insulation performance, it is an important material to improve the energy saving level of the door. In recent years, it has been widely used in construction. With the continuous improvement of energy-saving standards and the special requirements of some users, ordinary can no longer fully meet the needs. Therefore, thermal insulation performance is a measure of the key technical indicators of production enterprises, but also an important standard for downstream home appliance enterprises to select qualified suppliers and products. There are many factors that affect the energy saving performance, such as material, structure, environment and so on. At present, the technologies to improve the energy-saving performance of home appliance glass mainly include the use of coated glass, vacuum structure, filling inert gas, improving edge heating technology and sealing technology.
Coating is to plate one or more layers of metal, alloy or metal compound film on the surface of home appliance glass to change the optical performance and meet some specific requirements. Since the heat transfer is two-way and simultaneous, the radiation heat transfer of the inner surface accounts for 58%. Therefore, by changing the properties to reduce the loss of thermal energy, it is effective to suppress the radiation of the inner surface.
