Intelligent anti-condensation and frost-proof glass

Abstract

The invention discloses a piece of intelligent anti-condensation and frost-proof glass. The intelligent anti-condensation and frost-proof glass comprises a first glass plate and a second glass plate, wherein one surface of the first glass plate is provided with an ITO (indium tin oxide) membrane; one surface with the ITO membrane of the first glass plate is bonded with the second glass plate through a PVC (polyvinyl chloride) adhesive sheet; the ITO membrane is divided into a plurality of independent open annular areas which are circumferentially nested together. According to the intelligent anti-condensation and frost-proof glass, the heating process is controlled according to an analysis result, and the refrigeration load of a low-temperature exhibition cabinet, a refrigerator and the like can be reduced while the demisting and defrosting can be guaranteed.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to an intelligent anti-condensation and frosting glass. Background technique [0002] Due to the low temperature of the outer surface of the cabinet doors of low-temperature display cabinets and freezers, it is easy to fog or even frost in humid environments such as supermarkets and canteens, which affects the display effect. The temperature of the outer surface of the glass can be increased by electrically heating the glass to prevent condensation and frost. At present, the electric heating glass can be realized by heating wire and conductive film coating, as described in the patent CN99113594. However, the existence of the heating wire will affect the line of sight, resulting in a decrease in the transparency of the display cabinet door; patent 201220506470.1 uses an ITO-coated conductive film, but it heats the entire glass surface, but in reality, due to the faster heat transfe...

[0002] Due to the low temperature of the outer surface of the cabinet doors of low-temperature display cabinets and freezers, it is easy to fog or even frost in humid environments such as supermarkets and canteens, which will affect the display effect

The temperature of the outer surface of the glass can be increased by electrically heating the glass to prevent condensation and frost. At present, the electric heating glass can be realized by heating wire and conductive film coating, as described in the patent CN99113594. However, the existence of the heating wire will affect the line of sight, resulting in a decrease in the transparency of the display cabinet door; patent 201220506470.1 uses an ITO-coated conductive film, but it heats the entire glass surface, but in reality, due to the faster heat transfer at the glass edge of the cabinet door, the temperature is relatively Lower, easy to condense and frost, so the overall heating will inevitably lead to a decrease in efficiency, and conflict with the cooling effect
