Overview
JIANGKAI NBC-LC-50 (-60 ℃) Thermal Shock Test Chamber is mainly used to test the tolerance of materials in extremely high temperature or extremely low temperature instantaneous alternating environment, simulating chemical changes or physical damage that may occur due to thermal expansion and contraction of products. The equipment adopts a PID automatic Control system to ensure the accuracy and Reliability of the test, and is suitable for evaluating the performance of material structures or composites under temperature Impact. The products are divided into two-box and three-box types, which meet a number of national standards and industry specifications.

2. Equipped with servo refrigerant Flow rate control technology and PWM cold control technology, effective energy saving is more than 30%, and energy consumption can be reduced by 40% under low temperature conditions.
3. The dual cascade Water-Cooled refrigeration system composed of French Taikang fully enclosed Compressor ensures rapid cooling and low temperature requirements of -60 ° C.
4. Equipped with Dual-Box and Three-Box test functions, in line with test specifications, the experiment cycle is carried out, and the defrosting cycle is long without affecting the Impact time.
5. Adopt pure aluminum fin evaporator, multi-wing centrifugal circulating fan and forced ventilated equilibrating temperature regulation method to improve Temperature uniformity and heat exchange efficiency.
6. Safety protection system includes multiple protection mechanisms such as overtemperature, overvoltage, overload and leakage.
7. At the end of the test, the product to be tested will automatically return to normal temperature to avoid frost and dew condensation and provide a sample protection mechanism.
Principle
The test chamber performs rapid temperature impact on the test area through the high temperature heat storage area and the low temperature cold storage area. The refrigeration system adopts a binary cascade cycle, including two refrigeration cycles of high temperature and low temperature. Energy transfer is carried out through evaporative condenser, and heat transfer in the working room is carried out to achieve cooling. The air conditioning system adopts the forced ventilated equilibrate temperature control method (BTC). Control system controls the heater output through PID operation according to the set temperature, and combines the energy adjustment of the refrigeration system to realize dynamic temperature equilibrate and rapid temperature conversion.

Steps
1. Set test parameters: Set the temperature Impact range, time and other programs through the Touchscreen controller.
2. Place the sample: Place the sample to be tested on the sample rack in the test area.
3. Select the running mode: Select the program running or constant running mode.
4. Start test: Start operation, the equipment automatically performs high and low temperature Impact cycle.
5. Monitoring process: Observe the set parameters, test Linear dispersion and running status through the controller.
6. End the test: After the test, the device automatically returns the sample to normal temperature.
7. Data storage: Save experimental data through RS232 or USB interface.
Notice
* The equipment should be used under the conditions of Ambient Temperature 5~ 40 ℃, Humidity ≤ 80% R.H and no condensation to ensure performance.
* Power supply voltage is AC380V 50~ 60Hz, Power 10~ 15KW, and connected correctly.
* Safety protection is provided, but the status of refrigerant, Compressor and electrical system should be checked regularly.
* Sample placement should not block the circulating air duct to ensure Temperature uniformity.
* The defrosting cycle is approximately once every 5 days and takes about 2 hours, without affecting the normal impact test time.
Before operation, please familiarize yourself with the controller function and the fault display alarm information to ensure that the PID parameters are set correctly.
* When moving the sample, pay attention to the way the sample holder stands to avoid colliding with the liner wall.
When not in use for a long time, turn off the device and disconnect the power supply according to the procedures.
