2. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate, and the outer shell of the box is sprayed with A3 steel plate, which increases the Appearance, texture and cleanliness
3. The replenishment tank is placed in the lower right part of the control box body, and has automatic protection for water shortage, which is more convenient for the operator to replenish the water source
4. The large observation window is equipped with lights to keep the box bright, and the use of tempered Glass embedded in the heating element can clearly observe the situation in the box at any time
5. The humidification system pipeline is separated from the control circuit board, which can avoid failure due to humidification pipeline leakage and improve safety
6. The piping circuit system of the water system adopts door opening, which is convenient for maintenance and repair
7. The box body insulation adopts ultra-fine fiberglass insulation cotton, which can avoid unnecessary energy loss
8. The left side of the box is equipped with a test hole with a diameter of 50mm, which can be used for external test power cords or signal cords
9. The temperature and humidity control instrument adopts a (7.0 inch) large screen screen, which is easy to operate and program edit
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. After the data and test conditions are entered, the controller has a screen locking 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 the function of automatic calculation, the temperature and humidity change conditions can be corrected immediately, making the 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 can be stabilized at the moment of opening the door
Principle
The test chamber uses the original French "Taikang" fully enclosed Compressor to achieve low temperature control through the refrigeration system, and the refrigeration system adopts a unit or binary low temperature circuit system design. The heating system adopts a fully independent system and a nickel-chromium alloy electric heating heater to achieve temperature rise. The humidification system adopts a built-in isolated, all-stainless steel shallow surface evaporative humidifier to achieve humidity control. The dehumidification system adopts an evaporator coil dewpoint temperature laminar contact dehumidification method. Through a multi-wing blower strong air supply circulation, the temperature and humidity distribution in the test area is uniform, and an accurate temperature and humidity alternating test environment is realized.
