What are the main functions of double-layer vacuum glass?
Function 1: Warm and comfortable, improve the environmental comfort. Keep the room comfortable and cool during the hot summer months and keep the room warm during the cold winter months. The double-layer vacuum glass relies on the special structure of the vacuum layer to effectively block the indoor and outdoor cold heat conduction, and the thermal conductivity K value can reach 0.48 w/m2·k-0.9w/m2·k. When the outdoor temperature is below 20 °C, the inner surface temperature of the double-layer vacuum glass is only 3-5 °C lower than the indoor air temperature, which eliminates the cold and heat radiation phenomenon of the insulating glass. Even if you stand in front of the window, there will be no feeling of coolness, which will improve the comfort of the indoor environment.
Function 2: Energy saving and environmental protection, significantly reducing the cost of cooling and heating. The double-layer vacuum glass has superior thermal insulation properties and the heat transfer coefficient K can be as low as 0.48W/m2K. Far more than the international level 10 standard. Its ability to block heat transfer is 8 times that of single glass, which is 3-5 times that of insulating glass. Energy saving effects and economic benefits are very obvious. Energy saving means reducing the consumption of coal for power generation, reducing emissions of CO2 and other gases, and reducing environmental pollution.
Function 3: Sound insulation and noise reduction Double-layer vacuum glass effectively blocks the transmission of sound due to the existence of vacuum layer, especially for medium and low frequencies with strong penetration. The weighted sound insulation of double-layer vacuum glass is above the international level 3, and the effective sound insulation can reach 35 decibels to 42 decibels, which meets the requirements of the green building evaluation standard. The combined vacuum glass can reach more than 5 grades, fully meeting the special requirements of five-star hotels and hospitals.
Function 4: Prevent condensation, make people feel the natural scenery outside the window. Double-layer vacuum glass relies on its strong thermal insulation performance, so that the dew condensation temperature is reduced below minus 22 ° C, which can reach minus 51 ° C, and there is no possibility of condensation inside the vacuum layer.
Function 5: Multi-purpose can be used in various fields such as green building, energy-saving home appliances, and scientific research.
The tempered vacuum glass V-glass has a life expectancy of more than 25 years. It has a high vacuum inner cavity, which makes the gas heat transfer negligible. At the same time, high-performance Low-E glass is used to greatly suppress the radiation heat transfer and ensure the heat transfer coefficient of V glass (U value). ) as low as .4W/(m2·K). At the same time, V glass insulation performance is 2-4 times that of insulating glass, 6-10 times that of single glass. It can meet the requirements of international passive room for door and window heat transfer coefficient when used independently.
