Abstract

The invention discloses composite cooling glass which comprises a first glass layer and a second glass layer that is arranged in a manner of being separated from the first glass layer. A sealed chamber is formed between the first glass layer and the second glass layer. The first glass layer comprises at least one piece of radiating refrigerating glass. The radiating refrigerating glass has high infrared radiance in a wave band of 7-14 [mu]m. The composite cooling glass can control the indoor temperature and transmits the indoor heat to outside in an infrared radiation manner, thereby reducingindoor refrigeration cost and satisfying an energy-saving and environment-friendly requirement.

Description

technical field [0001] The invention relates to a composite cooling glass. Background technique [0002] Glass is an important building material. With the continuous improvement of decorative requirements for buildings, the use of glass in the construction industry is also increasing. However, when people choose glass roofs today, in addition to considering its aesthetics and appearance features, they pay more attention to the thermal insulation effect of the glass. At present, there are three main ways to insulate glass: first, apply heat insulating glass film; second, use Low-E glass; third, use sunshade products. Although insulating glass can prevent the indoor temperature from being too high to a certain extent, it does not have the function of cooling. [0003] In the patent application number 201710601686.3, a radiative cooling glass curtain wall is disclosed, which includes ordinary glass layer, nano-radiative cooling composite material coating, air-tight interlayer...
