The application of vacuum glass in the field of household appliances

Due to the transparency and beauty of glass material, it has been widely used in high-end refrigerators, wine cabinets, display cabinets and other home appliance fields. At the same time, ordinary glass materials have undeniable problems: on the one hand, due to their high heat transfer coefficient and poor insulation effect, they have always been a weak link in reducing energy loss and consumption; On the other hand, the use of electroplating film to prevent condensation on glass doors also increases power consumption to a certain extent. In the context where energy conservation, emission reduction, and green environmental protection have become the trend, vacuum glass that is insulated, energy-efficient, and less prone to condensation provides a perfect solution to this contradiction.

According to the definition of heat transfer coefficient, the difference in ambient temperature on both sides of a glass door causes heat to transfer from the higher temperature side to the lower temperature side. The larger the temperature difference between the two sides, the more energy is lost. For the energy efficiency of glass, the lower the heat transfer coefficient, the less heat is lost, and vice versa. The heat transfer coefficient U value of vacuum glass is very low, especially tempered vacuum glass Landy V glass. The high vacuum cavity effectively blocks heat transfer, and the U value can be as low as 0.4W/(┫ · K). The insulation effect of 8.3mm thick V glass exceeds that of 1.5m thick brick wall, effectively preventing heat from outside the cabinet from entering the cabinet, playing a good "cold insulation" role and excellent energy-saving effect. At the same time, the "cooling" function of V-glass can reduce the start-up time of household appliance compressors, decrease the working coefficient of compressors, and significantly extend the service life of products.

At present, the glass doors of refrigerators widely used in the market are single or double hollow structures. In order to prevent condensation of the hollow glass, a layer of electroplating film is usually applied to the surface of the glass, which invisibly increases power consumption. The high vacuum chamber of the Randy V glass does not have internal condensation problems, and its high thermal resistance greatly reduces the surface dew point. It does not condense even at minus 50 ℃, and the ultra-low dew point gives the home appliance freezer a transparent visual effect. In addition, the 8.3mm thick V-glass weighs only 20kg/┫, with a lightweight structure that not only reduces the overall weight of the freezer, but also reduces the material of the door frame, thereby lowering the overall cost.
