Solar radiation chamber



Solar radiation chamber
Main Technical Parameter
Temperature range 10℃~+70℃(without lighting) Remark:
1 All tested in empty chamber condition (except indicated), according to GB/T5170-2008
2 Data for air cooling chamber is tested when the room temperature is 25℃, with good ventilation; normal use in the event of room temperature between 25℃ and 35℃, with some influences on low-temperature range, cooling down rate and thermal load capacity.
3 Data for water cooling chamber is tested under the conditions that water temperature is no more than 28℃, water pressure is between 0.2MPa and 0.6MPa and the pressure difference between in and out water is no less than 0.2MPa
Temperature fluctuation ≤±0.5℃(without lighting)
Temperature
uniformity
≤2℃(without lighting)
Temperature deviation ±2℃(without lighting)
Humidity range 40%~98%RH(without lighting) (See Humidity Range Drawing)
Humidity deviation +2~-3%(>75%RH),
±5%(≤75%RH)(without lighting)
Heating up time ≤60min(room temp. ~+70℃)
Illumination intensity (700~1120)±10% W/m2(adjustable)
Illumination time 0~99h99min adjustable
During the illumination, the temperature in the chamber should rise to the setting temperature control value with an almost linear speed and keep it stable (the typical setting value is + 55 ℃ and 40 ℃). During no illumination, the temperature in the chamber should drop to the setting temperature control value with an almost linear speed and keep it stable (the typical setting value is +25℃). Under different test procedures, the relations between the temperature, irradiation and time during testing are shown in Chart 2.
Spectral energy and tolerance: should meet the requirements in Table 1
Test duration Can adjust in the range of 0~999h, and the test can be performed automatically according to the following test procedures:
Test procedure A: 24 hours a cycle, 8 hours illumination and16 hours no illumination. Test cycle can be set.
Test procedure B: 24 hours a cycle, 20 hours illumination and 4 hours no illumination. Test cycle can be set.
Test procedure C: Continuous illumination. Test cycle can be set.
Light tube cooling Air cooling(The effective use life of metal halide lamp tubes is 800~1000 hours under normal use)
Air speed The air speed of chamber is adjustable in the range of 0.5~1.5m/s via the converter.
The comparison tables for air speed and converter are attached to the equipment instruction book.
