5. The humidification system piping is separated from the control circuit board to enhance safety.
6. Waterways and circuit systems are door-opened for easy maintenance and repair.
7. The box body insulation adopts ultra-fine fiberglass insulation cotton to reduce energy loss.
8. The left side of the box is equipped with a test hole for external test lines.
9. The temperature and humidity control instrument is a 7.0-inch large screen, which supports Chinese and English interfaces and real-time Linear dispersion display.
10. The controller has a capacity of 100 programs and 1000 segments of 999 cycle steps, and supports screen locking and RS-232/RS-485 communication.
11. Automatic calculation function corrects temperature and humidity changes for accurate and stable control.
12. The refrigerator adopts the original French "Taikang" fully enclosed Compressor, and the refrigeration system is a unit or binary low temperature circuit design.
13. Multi-wing blower with strong air supply circulation, uniform temperature and humidity distribution, wind pressure and wind speed meet standards.
14. The heating, cooling, and humidification systems are independent, reducing test costs and failure rates.
Principle
The test chamber simulates high and low temperature or heating and humidity environment through temperature and humidity control system, uses refrigeration system to achieve cooling, heating system to achieve heating, humidification system to adjust humidity, and ensures uniform distribution of temperature and humidity in the test area through air circuit circulation system. The controller automatically calculates and corrects temperature and humidity changes to maintain a stable environment.
Applications
Aerospace Products, Information Electronic Instruments, Materials, Electrical, Electronic Products, Various Electronic Components
Standards
GB/T10592－2008、GB/T10586－2006、GB/T2423.1－2008、GB/T2423.2－2008、GB/T2423.3－2006、GB/T2423.4－2008、GJB150.3A-2009、GJB150.4A-2009
Steps
Connect the power supply to ensure that the voltage meets the requirements of AC220V +/- 10% 50Hz or AC380V +/- 10% 50Hz three-phase five-wire system.
2. Open the control instrument, select the Chinese and English interface, and edit or select the test program.
3. Set temperature and humidity parameters, such as temperature range -20~ 150 ℃, humidity range 30~ 98% R.H.
4. Start the equipment and monitor the real-time operation of Linear dispersion to ensure stable temperature and humidity.
5. After the test is completed, turn off the device and disconnect the power.
Notice
• Operating Environment Temperature should be 5 ℃~ 30 ℃, humidity ≤ 85% R.H.
• Avoid touching the controller screen artificially to prevent accidental shutdown.
• Regularly check the replenishment tank to ensure that the water source is sufficient and avoid triggering water shortage protection.
• Pay attention to the safety of waterways and circuit systems during maintenance, and follow the door opening operation.
• The test hole is closed in time after use to prevent energy loss.
• Do not open the door frequently when the equipment is running, so as not to affect the stability of temperature and humidity.
• Pay attention to safety protection functions, such as leakage, short circuit, over temperature, etc., and deal with abnormalities immediately.
