Analysis of why the glass door of the refrigerator adopts transparent glass

2022/12/13

Why tempered vacuum glass is used more in freezer glass doors, seven advantages of tempered vacuum glass:

1. Tempered vacuum glass. It adopts low-temperature sealing technology, which avoids the loss of safety function caused by tempered glass annealing caused by traditional high-temperature technology, and completely retains the impact resistance and wind pressure resistance of tempered glass. Capable of meeting safety glass specifications without lamination.

2. The heat insulation function of V-shaped glass is 2-4 times that of insulating glass. The high vacuum inner cavity can neglect the heat transfer of the gas. At the same time, high-performance low-e glass is used to greatly suppress radiation heat transfer, and ensure that the heat transfer coefficient (U value) of V glass is as low as 0.4W/(M2·K).

At the same time, the thermal insulation performance of V glass is 2-4 times that of insulating glass, and 6-10 times that of single-layer glass.

3. The expected service life of V-shaped glass can reach more than 25 years. It has a high-vacuum cavity, so it can ignore the heat transfer of the gas.

At the same time, the use of high-performance Low-E glass can greatly suppress radiation heat transfer, and ensure that the heat transfer coefficient (U value) of V glass is as low as 0.4W/(M2·K). At the same time, the thermal insulation performance of V glass is 2-4 times that of insulating glass, and 6-10 times that of single-layer glass.


4. The thickness of V-shaped glass is only one-sixth of its thickness, and the weight of V-shaped glass per square meter is less than 10 kg.

At the same time, V-shaped glass uses less Low-E glass, the glass is more transparent, and has a good lighting effect.

5. Eliminates internal condensation of V-shaped glass. Compared with the condensation problem caused by the temperature difference inside and outside the insulating glass, the high vacuum V-shaped glass can eliminate the condensation phenomenon.

At the same time, the excellent thermal insulation ability prevents condensation on the inner surface of the glass even when the outdoor temperature drops to -40°C.

6. Effective noise reduction V-shaped glass has obvious sound insulation effect on medium and low frequency noise with strong penetrating power. The high-vacuum cavity of the V-shaped glass effectively blocks the transmission of sound.

For every 5 dB difference, the hearing sensitivity of the human ear changes by 3-4 times. According to the professional weighted sound insulation loss rate, the sound insulation function of V glass can reach 39 dB when the outdoor noise is 75 dB, which is far better than the specification of 29 dB for insulating glass, especially for the interference of medium and low frequency noise on people, such as traffic The effect of noise and construction noise is obvious.

7. V glass is not affected by the application area, height and installation angle in various environments.

Even if there is a large height difference between the production site and the application site, the high vacuum inside the V-shaped glass will not cause the inner cavity to expand or contract. At the same time, the heat transfer coefficient of v-glass is stable when used horizontally or obliquely. It can be installed on the top of the building and on the sloped roof to ensure energy saving.
