Problems solved by technology
The traditional hollow glass dew detection device uses dry ice (solid carbon dioxide, temperature lower than -70°C) as the cold source to cool the cold end. The structure is simple, but it is difficult to control the temperature of the cold end, and the accuracy of the test results is low.
Moreover, dry ice cannot be purchased in many areas of the country, which makes it impossible to conduct the dew condensation performance test of insulating glass

The invention discloses a condensation detector for hollow glass, and belongs to the field of detection of condensation of hollow glass. The detector includes a cold end and a refrigeration unit. The cold end includes a refrigeration part having a hollow structure, and the refrigeration unit includes a condenser, a primary compressor, a heat exchanger, a secondary compressor. The primary compressor is connected to the condenser through a first pipe to form a first loop. The primary compressor is connected to the heat exchanger through a second pipe to form a second loop. The secondary compressor is connected to the condenser through a third pipe to form a third loop. The secondary compressor is connected to the refrigeration unit through a fourth pipe to form a fourth loop. The first and second compressors are filled with a refrigerant. Whether dew is formed in hollow glass can be detected in a temperature range from 0 DEG C to -60 DEG C. The detector is independent from dry ice, so that the detection is not limited by areas and time. The detection precision of the detector is improved.
Description
technical field [0001] The invention relates to the field of dew condensation detection for hollow glass, in particular to a dew condensation detection device for hollow glass. Background technique [0002] Insulating glass is a CCC certified (compulsory quality certification) product in my country. The national standard "Insulating Glass" GB / T11944-2012 requires the dew condensation temperature of insulating glass to be lower than -40°C, and the experimental sorting temperature should be lower than -60°C. The traditional insulating glass dew detection device uses dry ice (solid carbon dioxide, temperature lower than -70°C) as the cold source to cool the cold end. The structure is simple, but it is difficult to control the temperature of the cold end, and the accuracy of the test results is low. Moreover, dry ice cannot be purchased in many areas of the country, which makes it impossible to carry out the dew condensation performance test of insulating glass. Contents of th...
