What is the principle of hotel glass ironing?

Heat-absorbing glass Heat-absorbing glass is a glass body doped with metal ions to selectively absorb solar energy and present different colors at the same time. Heat absorbing glass can also be produced by coating. Energy-saving of heat-absorbing glass is to convert 30% ~ 40% of light energy when sunlight passes through the glass into heat energy, which is absorbed by the glass, and the heat energy is emitted in the form of convection and radiation, thus reducing solar energy from entering the room.

Insulating glass separates two pieces of glass with effective sealing material and spacer material, and desiccant is installed between the two pieces of glass to absorb moisture, thus ensuring that the inside of insulating glass is a dry air layer for a long time, without moisture and dust; At the same time, insulating glass is easy to produce in large quantities, so insulating glass is widely recommended in new buildings. Therefore, the heat-absorbing glass has good heat insulation performance. If the insulating glass adopts heat-absorbing glass, the heat insulation effect will be more obvious.
