Overview
JIANGKAI NBC-LC-80 (-60 ℃) Thermal Shock Test Chamber is mainly used to test the tolerance of materials under the instantaneous impact of extremely high temperature or extremely low temperature. It simulates the situation that materials are not continuously in high and low temperature environments, and can complete the test in a short time. The equipment adopts a PID Control system to ensure the accuracy and Reliability of the test. It is used to detect chemical changes or physical damage caused by thermal expansion and contraction. The products are divided into two-box and three-box, which meet a number of national standards and industry specifications.
Features
1. Adopt programmable color screen TEMI8226S Touchscreen controller imported from Korea, with intuitive operation and strong data saving function.
2. It has functions such as booking the switch machine, ending the planning setting, and automatically saving the data during power outages. Linear dispersion.
3. Support real-time experimental Linear dispersion analysis, equipped with RS232, USB Data storage interface.
4. At the end of the test, the product to be tested will automatically return to normal temperature to avoid frost and dew condensation protection mechanism.
5, the use of servo refrigerant Flow rate control technology, effective energy saving of more than 30%.
6. The experiment was carried out in a cycle, and it was effective to defrost once every 5 days. It only took 2 hours to defrost, which did not affect the impact time.
7. Adopt pure aluminum fin evaporator to effectively reduce energy storage time and Energy consumption.
8. With Dual-Box and Three-Box testing capabilities, meeting test specifications.
9. Adopting new PWM cold control technology can reduce energy consumption by about 40% under low temperature conditions.
10, Equipped with a complete Safety protection system, including overtemperature, overvoltage, overload, leakage and other multiple protection.
Principle
The test chamber adopts the forced ventilated equilibrate temperature control method (BTC). Under the condition of continuous operation of the refrigeration system, the Control system controls the output of the heater through PID operation according to the set temperature point to achieve dynamic equilibrate. The refrigeration system adopts a binary cascade Water-Cooled refrigeration system composed of imported fully enclosed Compressors, which includes two refrigeration cycles of high temperature and low temperature. The energy transfer is carried out through evaporation condenser, and the thermal energy in the working room is transferred out to achieve cooling. The refrigeration cycle is based on the principle of reverse carrot cycle, and the purpose of cooling is achieved through the process of compression, condensation, expansion and evaporation.

Steps
1. Set the required Temperature Impact Program, Temperature range and time parameters through the Touchscreen controller.
2. Place the sample to be tested in the sample testing area.
3. Start the equipment and the program runs automatically to realize the alternating impact of the high temperature heat storage area and the low temperature cold storage area on the test area.
4. The equipment completes the temperature conversion within 5 minutes and cycles the test according to the set program.
5. After the test, the equipment automatically warms the sample back to normal temperature to avoid frost and condensation.
6. View, save or export experimental data and Linear dispersion through the controller.
Notice
• Ambient Temperature of the equipment should be maintained between 5 ° C and 40 ° C, Environmental humidity ≤ 80% R.H.
• To ensure performance (e.g. minimum temperature -65 ° C), it is recommended that Ambient Temperature ≤ 30 ° C and no condensation.
Equipment is equipped with multiple Safety protection, but the operation still need to pay attention to observe the running state, if there is any abnormal alarm need to be dealt with in time.
• Perform regular equipment maintenance, such as defrosting operations according to equipment prompts.
• Sample placement should not hinder air circulation in the box to ensure Temperature uniformity.
• Non-professionals should not disassemble or repair core systems such as refrigeration and electrical.
