Ii. System configuration and technical description:

1. Box structure

1) The box is made of CNC equipment, advanced technology, smooth lines, beautiful and generous

2) The inner box is made of 1.2mm thick 304SUS advanced stainless steel wire drawing plate, and the outer box is made of 1.5mm thick high-quality cold-rolled steel plate electrostatic spraying

3) The insulation material between the inner box and the outer box is high-quality ultra-fine glass fiber insulation cotton, which has good temperature insulation effect. Imported sealing materials and unique silicone sealing structure are used between the door and the door frame, which has good sealing and aging resistance

4) The air duct in the box adopts a double circulation system, which is composed of two long-axis axial flow fans, two stainless steel multi-wing centrifugal wind turbine and circulating air duct. The temperature in the upper air outlet and the lower air inlet bellows is uniform, which improves the air flow, heating and cooling ability, and greatly improves the temperature uniformity of the test chamber

5) The air outlet is adjustable shutter type air outlet

6) The heater is made of stainless steel 316L fin heat dissipation heating tube, which has fast heating and long life

2, refrigeration system

1) Using French "Taikang" or Danfoss "Meyoule" cascade refrigeration compressor unit (air cooling)

2) Refrigeration compressor: In order to ensure the cooling rate and the minimum temperature requirements of the test chamber, the test chamber uses a cascade refrigeration system

3) The design of the refrigeration system should have energy regulation technology, an effective treatment method can ensure the normal operation of the refrigeration unit and can effectively adjust the energy consumption and cooling capacity of the refrigeration system, so that the operating costs and failure rate of the refrigeration system are reduced to a more economic state.

4) Refrigeration accessories: air-cooled coil condenser, fin type multi-stage evaporator, the main refrigeration accessories and control devices are imported originals, such as: the United States "Aigao" filter dryer; Italian "Castor" solenoid valve;

5) Refrigerant: imported R404R23

6) Cooling method: air cooling

3. Measurement and control system

Using cold and heat shock tester controller, liquid crystal touch screen double temperature programmable, high precision, stable control, the controller uses 7.0 inch LCD LCD display touch screen, set value, measurement value, time, heater and other working states can be visually displayed, and has automatic test operation and PID

1) Parameter self-tuning function. The setting of control parameters adopts the human-machine dialogue mode of the Chinese interface, the interface is friendly, and the automatic operation function of the refrigerator can be realized only by setting the temperature. The control system uses intelligent control software system, with automatic combination of refrigeration, heating and other subsystems working conditions, so as to ensure high precision control in the entire temperature range, to achieve the purpose of energy saving and consumption reduction. The perfect detection device can automatically carry out detailed fault display and alarm, such as when the test box is abnormal, the controller will automatically display the fault state. Optional RS232 computer interface and communication software.
