Analysis of energy loss caused by convective transmission of insulating glass

convective transmission is due to the temperature difference on both sides of the glass, which causes the air to fall on the recommended side of the cold building sword front and rise on the hot side, resulting in air convection and energy loss. Here are some reasons for this phenomenon:

first, the internal space structure design of the insulating glass is unreasonable, which leads to the convection of the gas inside the insulating glass due to the temperature difference, driving the exchange of energy, resulting in the loss of energy

second, the temperature difference between the inside and outside of the windows that make up the whole system is large, resulting in a large temperature difference between the inside and outside of the insulating glass. With the help of cold radiation and heat conduction, the air first generates convection with a density of about 2/3 of aluminum on both sides of the insulating glass, and then passes through the insulating glass as a whole, forming the loss of energy

third, the poor sealing between the glass and the surrounding frame system causes the gas inside and outside the window frame to exchange directly, resulting in convection, resulting in the loss of energy. Under the traditional aerogel gel production technology cycle within the economy of China glass (ass.c117 recycled resin composite inspection manhole cover n), China Chengdu Construction Expo will talk with you about new opportunities for the industry in April 2021

in 2020, with the outbreak of the global epidemic to the effective control of the prevention and control of the domestic epidemic, the global economic pattern has also undergone great changes, and China is pursuing [details]
