Xenon arc lamp aging test chamber GB-OXD-15P
1.Profile
Xenon lamp aging test chamber simulates the full spectrum lamp with Xenon arc lamp to reappear the destructive wave. It serves for the environmental simulation and accelerated test for research and development, product development and quality control. Besides, the chamber also applies to the choice of new material, weathering test after composition of material and improvement for the current material. It simulate different environment, and show the material changes under the explosion of sunlight.
The chamber meets the standard: GB/T16585-1996 , GB14522-93 , GB/T16422.3-97, ASTM D2565 and so on.
The Chamber is to determine the color fastness, aging resistance of textiles, plastics, coatings, rubber products or other materials by objecting to the simulated conditions of nature weather (sun, rain, temperature and humidity, etc.).

7.Working section of chamber
Condensation section of compressor.
a.Cooling system: as the core part of cooling system, we adopt one set of compressor of Tecumseh from France in this case to ensure the cooling requirement in the working room.
b.For adjustment technology and design of cooling system, we take an efficiency processing way to ensure the adjustment for the cooling amount and consumption of cooling system under the normal running, to make the failure rate down to the economical statue.
c.Cooling evaporator: it locates in interlayer at one side of chamber which ventilate by force from blast motor to exchange heat fast.
d.Cooling method of cooling system: forced air cooling Cooling refrigerant：Environmental R404a；
Heating system
a. Heating method: heating directly in the chamber;

c. With SSR (solid relay)output control, without noise, reliable working, long service life time, fast switching, low interference from outside, and easy operation etc..
Rain system.
it consists of nozzle, solenoid valve, water-supplying and connecting pipe.
Lighting system.
It consists of xenon lamp, lamp cover, lamp contactor and other controlling parts. Energy compensation is got by adjusting samples distance, pressure and current.
Wind system
It locates in the interlayer at the back of chamber, there are heater, fan blade, evaporator, PT100 temperature samples sensor etc.. when wind machine running, the air is intaken to the channel from working room, and blow out from the bottom after cooled; the air exchanged in the working room with samples is intaken again to the channel and mix; after several circulation, it will reach the purposed temperature, and ensure the high index of temp. and humid in the chamber at the same time.
Cooling dehumidification system
take the compressor of world brand Tecumseh from France to keep constant temperature, decrease the humidity in the working room and cool the xenon lamp.
Humidification
Steam generator: to generate steam from water
Water level control: control the water inlet by solenoid valve, and water level by liquid level switch to provide the signal for water-supply and warning.
Air circulation section
Cycling channel and winding machine inside the chamber, it uses the high efficiency cooling machine and energy adjusting system, efficiency heat exchange to reach the aim of temperature change, which also improves the airflow and heat exchange between airflow, heating and humidification, as a result, it improves the humidity uniformity in the working room.
