I. Overview of Xenon Lamps Aging Test Chamber:
Dongguan Hongjun Instrument & Equipment Co., Ltd.'s HJ/CQ-Series Xenon Lamps Aging Test is a comprehensive climatic test device. In addition to climate aging tests, it can also conduct tests on the refractive index resistance of high-performance materials. This involves evaluating the material's refractive index resistance by exposing high polymer materials to artificial light sources simulating sunlight passing through glass. The test simulates and intensifies the main climatic factors such as light energy, temperature, rainfall or dew, and humidity. It uses xenon arc lamps capable of simulating the full sunlight spectrum to reproduce destructive light waves present in different environments. The Xenon Lamps Weathering Test Chamber provides environmental simulation and accelerated tests for scientific research, product development, and quality control. It can be used for tests such as selecting new materials, improving existing materials, or evaluating changes in durability after material composition changes. It is suitable for plastics, rubbers, paints, coatings, inks, papers, food, textiles, automotive parts, packaging materials, construction materials, electronic and electrical products, etc.
The Xenon lamp test chamber employs a xenon arc lamp capable of simulating the full solar spectrum to reproduce destructive light waves present in various environments, providing environmental simulation and accelerated testing for scientific research, product development, and quality control.
The SN Xenon lamp test chamber is used for tests such as selecting new materials, improving existing materials, or evaluating changes in durability after material composition alterations. It effectively simulates the changes materials undergo when exposed to sunlight under various environmental conditions.
Simulate full sunlight spectrum:
SN measures the material's resistance to optical rotation by exposing it to ultraviolet (UV), visible light, and infrared light. It utilizes filtered xenon arc lamps to produce a full sunlight spectrum with a high match to natural sunlight. The use of properly filtered xenon arc lamps is a method for testing the sensitivity of products to longer wavelengths of UV and visible light in direct sunlight or sunlight passing through glass.
Optical Rotation Resistance Test for Indoor Materials
Due to long-term exposure to fluorescent lights, halogen lights, or other illuminating lamps, products placed in retail points, warehouses, or other environments will also undergo significant photo-degradation. The SN Xenon Light Test Chamber can simulate and reproduce the destructive light in such commercial lighting environments, and can accelerate the testing process with higher intensity.
Simulated climatic environment:
In addition to the photo-degradation test, the SN Xenon Lamps Test Chamber can be converted into a climate aging test chamber by adding a water spray option, simulating the effects of outdoor humidity on materials.
Relative Humidity Control
Some models of SN Xenon Lamps Test Chambers offer relative humidity control functionality, which is also crucial for many moisture-sensitive materials, and many testing protocols require humidity control.

It includes a mechanical speed device for the sample frame, an Xenon lamp condensation water tank, and various actuating devices such as a pump. The electrical control cabinet is located on the right side of the test chamber for easy operation.

The refrigeration system features a compressor as its core, and in this solution, we utilize a single Tecumseh fully enclosed compressor from France to ensure the cooling requirements of the workspace.
The refrigeration system design employs energy regulation technology, an effective approach that ensures normal operation of the refrigeration unit while also adjusting the energy consumption and cooling capacity of the system, thereby reducing the operation costs and failure rates to a more economical level.
※Cooling Evaporator: The evaporator is located within the air duct interlayer at one end of the test chamber, forced-ventilated by a blower motor for rapid heat exchange.

Refrigerant: R404a; (Environmentally friendly refrigerant)
Heating Section:
Heating method: Direct heating inside the test chamber.
Stainless steel finned heating tubes are used, ensuring a stable heating rate and maintaining consistent internal temperature without sharp fluctuations. They offer advantages such as corrosion resistance, high and low-temperature tolerance, no leakage, and easy installation.
With SSR (Solid State Relay) output control, offering noiseless operation, reliable performance, long lifespan, strong anti-interference capability, fast switching speed, minimal external interference, and ease of use.
Drizzle System
The rain system is mainly composed of nozzles, solenoid valves, water supply sources, and connecting hoses.
Lighting System:
The lighting system is primarily composed of Xenon lamp tubes, lampshades, Xenon lamp igniters, and various control devices. Energy compensation for the Xenon lamps is achieved by adjusting the distance between the frames and regulating the voltage and current.
Air Duct System
The duct system is located in the middle layer at the rear of the test chamber, housing devices such as heaters, fan blades, evaporators, and PT100 temperature sampling sensors. As the fan rotates at high speed, it draws air from the top of the work chamber into the duct, where it is thoroughly mixed with the heat from the heater and the coldness from the evaporator before being blown out from the bottom. The air, after exchanging heat with the test sample inside the work chamber, is then drawn back into the duct for mixing. This process is repeated to achieve the desired temperature, while also ensuring the test chamber maintains high humidity levels.
Refrigeration/Dew Point Control System
※Selected the "Thermokool" fully enclosed industrial refrigeration compressor from France. Mainly used for cooling Xenon lamp tubes and maintaining a constant indoor temperature and humidity level in the workspace.
Humidifier section:
Steam Generator: Device for producing steam by vaporizing water.

Gas Recirculation Section:
※Equipped with an internal recirculating air duct and fan, utilizing high-efficiency refrigeration units and energy regulation systems, the effective heat exchange is achieved through high-efficiency fans, to accomplish temperature changes. By improving the air's blowing airflow, the air flow and the heat exchange capabilities of the heating, humidifying, and air-cooling units are enhanced. Through the adjustable air damper at the exhaust outlet, the uniformity of temperature and humidity in the test chamber is significantly improved.
