4、 Box structure

1. Structural form of the test chamber: adopting an integrated combinationStructural design, usingThis method has a small footprint, compact structure, and beautiful appearance. The refrigeration unit is placed in an independent unit box to reduce the impact of vibration and noise during the operation of the refrigeration unit on the test box, and to facilitate the installation and maintenance of the unit. The electrical control panel is placed on the right side panel of the test box for easy operation

2. Outer wall material of the box: cold-rolled steel plate, surface treated with electrostatic spraying;

3. Inner wall material of the box: stainless steel plate (SUS304);

4. Insulation material: high temperature resistantfire preventionHard polyurethaneFoam or high temperature resistant and fire-resistantultrafinefiberglassinsulationCotton;

5．Test box doorEquipped with dual silicone sealing and sealing strip heating device, with self limiting heating belt to prevent condensation and frosting during testing;

6. Sample rack:Mesh styleStainless steel sample holder；

7. Cable testing hole: A sliding cable conduit is installed at the upper part of the sample rack and the top of the high-temperature test box;

5、 Refrigeration system

1. Refrigeration system and compressor: To ensure the cooling rate and low temperature requirements of the test chamber, the refrigeration system of this test chamberadoptThe original French "Taikang" fully enclosed compressor unit has the advantages of reasonable matching, high reliability, and easy use and maintenance;

2. The design of refrigeration systems applies energy regulation technology, which is an effective processing method that can ensure the normal operation of refrigeration units while effectively adjusting the energy consumption and cooling capacity of the refrigeration system, reducing the operating costs of the refrigeration system to a more economical state;

3. High quality oxygen free copper tube, nitrogen filled welding;

7. Refrigerant: Environmentally friendlyType refrigerantR404A、R23；

8. Refrigeration auxiliary components: The main refrigeration accessories and control components are all used, such as SPORLAN expansion valves from the United States, CASTEI solenoid valves from Italy, globe valves, and filters; RANCO pressure controller from the United States, etc.

6、 Heating system

1.The heater adopts a porcelain frame nickel chromium wire electric heater, which has low thermal inertia and long service life. The instrument outputs a controllable pulse duty cycle PID signal, which is controlled by a solid-state relay for smooth and reliable control.

7、 Control system

1. Control device: The human-machine interface adopts a color large screen (5.7 inches) LCD touch display screen, and the control interface adopts a fully Chinese display,canSet experimental parameters, curves, total operating time, segment total operating time, heater working status and time, etc. The programming of the control program adopts a human-machine dialogue method, with a user-friendly interface, and the automatic operation function of the refrigeration machine can be achieved by simply setting the temperature.

2. The control system uses an intelligent control software system, which has the ability to automatically combine the working conditions of subsystems such as refrigeration and heating, ensuring high-precision control throughout the entire temperature range, while achieving the goal of energy conservation and consumption reduction. The complete detection device can automatically display and alarm detailed faults. For example, when an abnormality occurs in the test chamber, the controller displays the fault status in Chinese characters. At the same time, it has the storage function of historical data table trend charts and historical fault records.Equipped with a communication interface, it can be directly operated by connecting to a computer, as shown in the following figure:
