The transparency and appearance of glass make it a perfect fit for a wide range of home appliance applications such as high-end freezer, refrigerator, wine cabinet, and display cabinet. However, ordinary glass material has its disadvantages that cannot be overlooked: on the one hand, because of its high thermal transmittance coefficient, the thermal insulation effect is poor. It has always been the weak link for reducing energy loss and consumption; on the other hand, to prevent condensation on the door, the use of electroplating film increases the energy consumption to a certain degree. In the context that emission reduction and environment protection have become the general trend, the vacuum insulated glass with thermal insulation, energy saving, and condensation free properties provides the ideal solution to this problem.
By the definition of thermal transmittance coefficient, the ambient temperature difference between the two sides of the glass will cause the heat being transferred from the side of higher temperature to the side of lower temperature. The bigger the temperature differences between the two sides, the larger the loss of energy. As to the energy efficiency of glass, the lower the thermal transmittance coefficient, the less the loss of heat, and vice versa. Vacuum insulated glass, especially the tempered vacuum insulated glass LandVac® made by LandGlass has a very low U-value. While the heat transfer is effectively blocked by the high level vacuum chamber, its U-value can be as low as 0.4W/(㎡·K). The thermal insulation effect of an 8.3 mm thick LandVac is better than that of a 1.5m thick brick wall. It effectively keeps the heat outside the cabinet from getting in, resulting in a great “coldness maintaining” effect with tremendous energy saving. In addition, the “coldness maintaining” effect can reduce the start-up time for the home appliance compressor and its working coefficient, significantly extending the service life of the appliance.
At present, a large number of glass doors used on freezers are dual-pane or triple-pane insulated glass. In order to prevent condensation, they generally place a layer of electroplating film on the glass surface which in turn increases the energy consumption. While the high vacuum chamber of LandVac vacuum glass effectively eliminates the dew condensation, the high thermal resistance property of LandVac vacuum insulated glass significantly lowers the surface dew point. It can maintain condensation free under the temperature of 50 below zero. The ultra-low dew point gives the freezer and household appliances a transparent visual effect. In addition, the 8.3mm thick LandVac weighs only 20kg/㎡. The lightweight structure reduces not only the overall weight of the freezer but also the material for the door frame, therefore, the total cost.
As one of the new generation energy saving materials heavily promoted by the State, LandVac vacuum glass offers apparent advantages such as low thermal transmittance coefficient, condensation free, light weight and thin structure that have great significance and potential to the development of energy efficient home appliances. Successfully commercialized LandVac is being known by more and more renowned domestic and international enterprises. Besides the home appliances field, it has demonstrated outstanding performance in military, construction, agriculture, and many other fields. In the future, it surely will make even greater contribution to energy conservation, green and environmental protection worldwide.
