Fourth, the box structure
1. The inner liner is imported (SUS304) high quality mirror stainless steel plate;
2, insulation material: high density glass fiber cotton. Insulation thickness is 80mm;
3, the use of no reaction door handle, the operation is easier;
4. The bottom of the machine is made of high quality fixed PU movable wheel;
5. The outer shells are made of high-quality (t=1.2mm) A3 steel plate CNC machine tools, and the surface of the outer casing is sprayed, which is more smooth and beautiful.
6. Stirring system: long-axis fan motor, high-low temperature resistant stainless steel multi-wing impeller, to achieve vertical convection vertical diffusion cycle;
7. Double-layer high-temperature resistant high-strength sealing strip is used between the door and the box to ensure the sealing of the test area;
8. The observation window adopts multi-layer hollow tempered glass and inner glued sheet type conductive film (the test process can be clearly observed);
9. Test hole (left side of the machine) 50mm (imported original) can be used for external test power line or signal line (the aperture or number of holes must be increased).
V. Control system The temperature and humidity control instrument adopts the “Korean original TEMI880†large screen-liquid crystal display-programmable microcomputer PID control SSR output operation, all imported large LCD color touch screen screen, the screen operation is simple, the program editing is easy;
Accuracy: 0.1 ° C (display range);
Resolution: ±0.1 °C;
Temperature sensor: PT100 platinum resistance temperature measuring body;
High-intensity heating (2KW×1) electric heater using far-infrared nickel-chromium alloy;
The main parts of the electrical control are imported (Schneider) components to better control the temperature.
Compressor: fully enclosed French Taikang brand refrigeration method: the superimposed compression refrigeration and insulation system adopts ultra-fine glass fiber filled insulation zone, and the inner and outer bile connection parts are made of non-metal resistant high and low temperature materials, effectively reducing the temperature conduction box door seal using refined silicon. Rubber, so there is no aging and hardening under high and low temperature. The refrigeration system is overloaded, the refrigeration system is overpressured, there are leakage, operation indication, automatic shutdown after fault alarm, etc.
Sixth, protection / humidification system
1. The refrigeration system is overloaded and the refrigeration system is overpressured;
2. The overall equipment is over temperature, the overall equipment is out of phase/reverse phase, and the overall equipment is timed;
3. Others have leakage, water shortage, operation indication, automatic shutdown after fault alarm, etc.
4. Humidity control adopts P?I?D+S?S?R, and the system coordinates control with the channel.
5. The external boiler steam humidifier has the function of energy saving and consumption reduction, which can save 70% energy consumption;
7. Far-infrared stainless steel high-speed heating nickel-chromium alloy heater;
