1、 Product Name and Model
1.1 Product Name | Insulated glassUltraviolet (UV) Radiation Test Chamber |
1.2 Model No. | ZK-Z/02 |
2、 Principle of the Test Box | |
This test evaluates the hollow glass's resistance to ultraviolet radiation. After irradiation, if there are volatile substances like organic matter, water, or oil in the sealing adhesive, they can be adsorbed onto the inner surface of the glass through a cooling water tray. It also checks the creep of the sealant strip under ultraviolet radiation.Situation. | |

5.3 Refrigerant 5.4 Condenser Condensing Evaporator | Utilizing environmentally friendly refrigerants Shell and tubeHeat Exchanger Finned heat exchanger |
5.5 Cooling evaporator | Utilizing copper coil, positioned within the water tank of the test box |
6、 Electrical Control System | |
6.1 Temperature Control Instrument
6.2 Sensor 6.3 Execute electronic components
6.4 Control Instrumentation Section |
Pt100 Platinum Resistance Element Schneider contactors and residual current protectors from FranceIntegratedBrand Solid State Relay This control system meets the functional requirements of climate cycle test chambers, including: 1) Automatically completes the UV radiation resistance test for hollow glass as specified in GB11944-2012. 2) Automatic temperature control 3) Real-time display of test data. |
7、 Safety Protection Device | |
7.1 Test Chamber | Total power phase sequence and phase failure protection Leakage Protection Fan motor overheating Overcurrent Protection Water Shortage Alarm Over-temperature Protection |
7.2 Safety Mechanism | The heating cannot be activated when the recirculating pump is not running; heating can only begin after the recirculating pump is started. Over-temperature Protection for Enclosure: Once this over-temperature protection is activated, it will cut off the main power supply to the enclosure. |
