9. Total installed capacity: approximately 30KW

10. Box material: Made of storage plate, with SUS304 # stainless steel on the inner wall and color steel plate on the outer wall

11. Insulation material: Hard flame-retardant polyurethane foam, thickness 50mm

12. Box door: single door, equipped with a 400mm × 500mm conductive film tempered glass anti condensation observation window on the door

13. Floor: 50mm thick insulation board is used, and the bottom of the studio is about 200mm above the ground;

14. Install anti reverse lock door locks and ventilation devices indoors.

15. Configure RS-232 computer connection port for printing reports and outputting data

The technical data for the operation of the above equipment are all measured at room temperature of 20 ± 5 ℃, relative humidity ≤ 85% R.H. Under the non-linear condition of no load in the test chamber, the temperature and humidity remain constant for two hours. ）

3、 Air conditioning system:

1. Working principle: Forced ventilation and internal circulation, balanced temperature and humidity control: The control system amplifies, converts, and non linearly corrects the temperature signal collected inside the box, compares it with the set temperature value (target value), and obtains a deviation signal through PID calculation. The output adjustment signal automatically controls the output power of the heater/humidifier, so that the heating and heat dissipation in the laboratory reach a dynamic balance, ultimately achieving the goal of constant temperature

2. Air circulation device: Extended shaft centrifugal fan, long shaft external motor drive

3. Air heating method: using a dedicated spiral nickel chromium alloy resistive electric heater with a large heat dissipation area; PID+SSR drive control

4、 Humidification system:

1. Built in boiler steam humidifier.

2. Equipped with automatic water level compensation and water shortage alarm system.

3. Stainless steel high-speed humidification (18KW/380V) humidification tube.

4. Humidity control adopts P.I.D control.

5. Equipped with a tap water filtration device.
