3. Large observation window with lighting, using heating element embedded tempered Glass, easy to clearly observe the situation in the box
4. The humidification system pipeline is separated from the control circuit board to avoid failure due to leakage of the humidification pipeline and improve safety
5. The piping circuit system of the water system adopts door opening, which is convenient for maintenance and repair
6. The box body insulation adopts ultra-fine fiberglass insulation cotton to avoid unnecessary energy loss
7. The left side of the box is equipped with a 50mm diameter test hole, which can be used for external test power cord or signal cable
8. The temperature and humidity control instrument adopts a 7.0-inch large screen screen, which is easy to operate and easy to edit programs
9. The controller operation interface is available in Chinese and English, and the real-time operation Linear dispersion diagram can be displayed on the screen
10. With the capacity of 100 sets of programs and 1000 stages of 999 cycles, the MAX Maximum is set to 99 hours and 59 minutes per period
11. With screen lock function to avoid shutdown due to human touch
12. With RS-232 or RS-485 communication interface, you can design programs on the computer, monitor the test process, and perform functions such as automatic switch
13. With automatic calculation function, the temperature and humidity change conditions can be corrected immediately, making temperature and humidity control more accurate and stable
14. The refrigerator adopts the original French "Taikang" fully enclosed Compressor
15. Adopt a multi-wing blower for strong air circulation to avoid any dead ends and ensure uniform temperature and humidity distribution in the test area
16. The air path circulates the air outlet and return air design, the wind pressure and wind speed meet the test standards, and the temperature and humidity stabilize quickly at the moment of opening the door
17. The heating, cooling, and humidification systems are completely independent, which can effectively reduce testing costs, increase lifespan, and reduce failure rates
Principle
The test chamber realizes temperature and humidity control through a fully independent system of heating, cooling, humidification and dehumidification systems. The heating system adopts a nickel-chromium alloy electric heating heater, the refrigeration system adopts the original French "Taikang" fully enclosed Air-Cooled compression refrigeration method, the humidification system adopts a built-in isolated all-stainless steel shallow surface evaporative humidifier, and the dehumidification system adopts an evaporator coil dewpoint temperature laminar contact dehumidification method. Through a multi-wing blower strong air supply cycle, the temperature and humidity distribution in the test area is ensured to be uniform.

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
1. 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. Check the water level of the replenishment tank to ensure that the water source is sufficient
3. Set temperature and humidity parameters and test procedures through 7.0 inch Touchscreen
4. Select the Chinese and English operation interface and edit the test program
5. Set the test time (adjustable from 0 to 9999 minutes or hours)
6. Start the test program and monitor the real-time operation Linear dispersion
7. After the test is completed, the device automatically stops running
Notice
• Operating Environment Temperature should be maintained at 5 ℃~ + 30 ℃, humidity ≤ 85% R.H
• Regularly check the water level of the replenishment tank to avoid water shortage operation
• Pay attention to the door opening operation of the pipeline circuit system of the waterway system during maintenance and repair
• Avoid human touch of the controller screen to prevent unplanned downtime
• Pay attention to the safety protection functions of the equipment, including leakage, short circuit, over temperature, water shortage, motor overheating, Compressor overvoltage, overload, overcurrent protection
• Use the 50mm diameter test hole on the left side of the box when connecting the external test line
