Known for its high vacuity and ability to provide excellent heat insulation, condensation resistance, and sound insulation, vibrating insulated glass (IGU) (VIG) is used in a variety of applications around the world.
sunblock that provides protection from UV radiation from the sun
With regard to the structure of the VIG, the edge is soldered together and the center is separated by supports, resulting in the formation of a vacuum chamber. As a result of its design, the coefficient of heat transfer in its center is significantly lower than that in its edge, and when considering actual practice in the real world, the heat transfer coefficient in the edge is associated with the window frames. Therefore, the U value in the central area of the quisure insulated glass is solely measured for the purpose of parameter comparison and is not used for any other purpose.
When the VIG is positioned in the center of the room, heat transfer is accomplished through a variety of mechanisms, including radiation, support contact, and residual gas, among others. According to Jianzheng Tang's The Vacuum Insulated Glazing Heat Transfer Coefficient and the Calculation of the Condensation Temperature, when the vacuity is less than 0.1 Pa, it is possible to ignore the heat transfer from residual gas. In the case of VIG, the heat transfer coefficient is determined by the emissivity of the glass, which is shown in Formula 1.
It is necessary to consider both air heat transfer and glass radiation during the heating and cooling processes, with air heat transfer taking precedence over display cabinet insulated glass door radiation in the vast majority of cases. Comparing the coefficient of heat transfer of insulated glass to the same emissivity of the original glass on which it is based, the coefficient of heat transfer of insulated display cabinet door is significantly higher than the coefficient of vibrational induction from the insulated glass.
According to Table 2, if the temperature outside is 25 degrees Celsius, the temperature inside the vacuum observation box remains at 60 degrees Celsius for an hour; the surface temperature of the VIG (2 # observation window) measures 25.3 degrees Celsius, which is almost exactly the same temperature as the outside temperature. Vacuum observation boxes have been shown to be more effective at insulating than other types of observation boxes when compared to those of other types.
Nota bene: The values of R1 and R2 represent the thermal resistance of the inside glass and the outside glass, respectively. The values of Rradiation and Rradiation represent the thermal resistance of the radiation and the thermal resistance of the inside glass, respectively, represent the thermal resistance of the inside quisure insulated glass. Among the thermal resistances represented are Rsupport, Rair, Rvacuum, and Cvacuum, which represent the thermal resistance of the support, the thermal resistance of the gas residual, Rsupport, Rair, Rvacuum, and Cvacuum, which represent the thermal resistance of the vacuum, and the conductivity of the vacuum, which represents the conductivity of the vacuum.
The performance of insulating glass and VIG in terms of condensation is compared, and it is discovered that VIG outperforms insulated glass on this metric. Under the conditions of 25 degrees Celsius inside and 75% relative humidity, the temperature outside must be at least -69.5 degrees Celsius in order for the VIG to begin condensing; however, with insulated glass, the critical temperature only needs to be reached at -4 degrees Celsius before condensation can begin.
noise isolation provided.
As shown in Figure 4, the acoustic insulation performance is relatively poor in the frequency range of 160-6300 Hz for frequencies less than 500 Hz. This is especially true for frequencies less than 500 Hz. This is especially true for frequencies that are less than 500 hertz in frequency. Because low frequencies are more likely to cause the glass to vibrate, and because sound energy is transferred from one side to the other through the pillars, it is necessary to use low frequencies.
When operating in the frequency range of 500Hz to 3150Hz, the sound insulation properties of glass are considered to be moderately good. Specifically, the maximum level at 1250Hz is 42.5dB, and the lowest level is 35dB in this case. Based on the evidence presented above, VIG provides significantly better sound insulation properties than laminated glass and insulated glassFive-point-three-point-five-point-five VIG, for example, has a sound transmission loss of only 26dB, while the sound transmission loss of five-point-nine-point-five insulated glass is only 32dB, and the sound transmission loss of five-point-six-point-five laminated glass is only 32dB.
