This method not only refers to the case of continuous refrigeration system, the control system according to the temperature set point of the heater to control the output of the PID automatic operation by the results of the output, and ultimately achieve a dynamic equilibrium. ◆ air circulating means: built between the air circulation fan duct and the long axis of the stainless steel, the use of energy efficient refrigerators and regulating system for efficient heat exchange through efficient fan, to achieve the temperature change of the object. By adjustable air outlet adjustment bolt, thereby significantly improving the temperature uniformity of the chamber; ◆ air cooling method: multi-stage diaphragm type air heat exchanger. Fourth, high and low temperature manufacturer Qingdao Features: 1. Product appearance, reasonable structure, advanced technology, sophisticated material, with a simple and convenient operation and reliable performance of equipment performance. 2. The equipment is divided into hot box, cold boxes in two parts, picking off the unique structure and regenerative thermal storage heat effect, the test analytes move up and down through the basket in the cold box, in order to achieve thermal shock testing purposes. 3 . uses the most advanced measuring device, the controller uses a large color LCD touch man-machine interactive LCD human interface controller, simple, easy to learn, reliable, in English and the full system operating conditions, implementation and Setup program curve. 4. with 96 test specifications set independently, the impact time of 999 hours 59 minutes, cycle times can be set from 1 to 999, enabling automatic chiller operation, to achieve the greatest degree of automation, reduce operator workload, may at any Time ﹑ stop working automatically start running; 5. box on the left with a diameter of test holes 50mm, wiring for external power load test components. 6. can be independently set high and low temperature and thermal shock three functions of different conditions, and in execution thermal shock conditions, choose cold punch, punch the functional impact of the heat, with high and low temperature testing machine functions. 7. with a fully automatic, high-precision system loop, any mechanical movement, entirely PLC lock handle, all with automatic calculation PID control, temperature control and high accuracy. 8. advanced science airflow circulation design, the indoor temperature uniformity, avoid any dead ends; complete security protection devices, avoiding any possible security risks, ensure long-term reliability of the equipment can be set 9. defrost cycles and the number of automatic (manual) 10. Thermal Shock defrost temperature recovery time. for 5 minutes to complete. 11. The operation status display and the curve shows an abnormal condition occurs, and the cause of the fault and troubleshooting methods provide immediate automatically displayed on the screen, and the discovery of the input power is unstable, with an emergency stop device. 12. cascade refrigeration system using low-temperature loop system design efficient, refrigeration compressors imported European and American units, and using the coefficient of zero ozone green (HFC) refrigerants R507, R23. 13. Within the box material SUS304 stainless steel, Carton Material SUS304 stainless steel or cold rolled steel paint. Fifth, temperature measurement and control system ◆: Pt100 platinum resistance. ◆ control devices: the controller uses to independent research and development (KW-890) color LCD touch screen dual-loop temperature control system, which controls the display of imported color LCD touch screen (7 inches) to control the display of the controller with Chinese Operation Display Interface display, can display, set test parameters, the curve, the total running time, total running time segment, the heater working condition and calendar time. Preparation of the control program using interactive mode, user-friendly, just set the temperature can be achieved Autorun feature refrigerator. ◆ control system uses intelligent control software system, with automatic combination of refrigeration, heating and other subsystems working conditions, thus ensuring high-precision control over the entire temperature range, while achieving energy saving, saving purposes, improve the detection device can automatically detailed fault display, alarm, if an exception occurs when the chamber, the controller displays a fault condition with Chinese characters, along with historical trends and historical data sheets fault records storage.
