2. The replenishment tank is placed in the lower right part of the control box body, with an automatic water shortage protection function, which is convenient for the operator to replenish the water source.
3. The large observation window is equipped with lighting, and the heating element is embedded with tempered Glass, which can clearly observe the situation in the box.
4. The humidification system piping is separated from the control circuit board to avoid malfunctions due to water leakage and improve safety.
5. The piping circuit system of the waterway 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 or signal wires.
8. The temperature and humidity control instrument adopts a 7.0-inch large screen screen, which is easy to operate, easy to edit programs, and supports Chinese and English interface selection.
9. With a 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.
10. The controller has a screen lock function to avoid human touch shutdown.
11. With RS-232 or RS-485 communication interface, you can design programs on the computer, monitor the test process, and perform automatic switching.
12. With automatic calculation function, it can immediately correct the temperature and humidity change conditions, making the control more accurate and stable.
13. The refrigerator adopts the original French "Taikang" fully enclosed Compressor.
14. The refrigeration system is designed with a unit or binary cryogenic loop system.
15. Adopt a multi-wing blower for strong air circulation to avoid dead ends and distribute temperature and humidity evenly.
16. The air passage 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, effectively reducing testing costs, increasing lifespan, and reducing failure rates.
Principle
The test chamber precisely sets the temperature and humidity parameters through a programmable controller. The refrigeration system uses the original French "Taikang" fully enclosed Compressor to achieve low temperature control. The heating system uses a nickel-chromium alloy electric heating heater to heat up. The humidification system uses a built-in isolated all-stainless steel shallow surface evaporative humidifier to increase humidity. The dehumidification system uses an evaporator coil dewpoint temperature laminar contact dehumidification method. The multi-wing blower has a strong circulation air path to ensure uniform distribution of temperature and humidity in the test area, and corrects the conditions in real time through the automatic calculation function to achieve accurate and stable environment simulation.

4. Set the test time, adjustable from 0 to 9999 minutes or hours.
5. Start the test, the controller automatically calculates and corrects the temperature and humidity conditions, and monitors the real-time operation of Linear dispersion.
6. During the test, the conditions in the box can be observed through the large observation window lighting, and if necessary, the external circuit of the test hole can be used.
7. After the test, turn off the power supply and conduct maintenance inspections.
Notice
• Operating Environment Temperature should be maintained at 5 ℃~ 30 ℃, humidity ≤ 85% R.H.
• Avoid touching the controller screen artificially to prevent accidental shutdown.
• Regularly check the humidification system piping to prevent water leakage failures.
• During maintenance, the door opening design is used to facilitate the maintenance of waterways and circuit systems.
• Pay attention to safety protection functions, including leakage, short circuit, over temperature, water shortage, motor overheating, Compressor overvoltage, overload, overcurrent protection.
• Power frequency stability to avoid overvoltage or undervoltage operation.
