2. It has the functions of booking the switch machine, ending the planning setting, and automatically saving the data of the power failure. Linear dispersion.
3. Real-time experimental Linear dispersion analysis, equipped with RS232, USB Data storage connection 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. Using 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, and the defrosting only took 2 hours, 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. The dual cascade Water-Cooled refrigeration system composed of imported French Taikang fully enclosed Compressor has high refrigeration efficiency.
Principle
The equipment adopts the forced ventilated equilibrate temperature control method (BTC). When the refrigeration system works continuously, the Control system controls the heater output through PID operation according to the set temperature point to achieve dynamic equilibrate. The refrigeration system adopts an inverse carro cycle, which is composed of two refrigeration cycles at high temperature and low temperature. Energy is transferred through evaporation condenser to transfer heat in the working room to achieve cooling. The air circulation device exchanges heat through the built-in fan to improve the airflow to increase Temperature Uniformity.

Steps
1. Setting program: Set temperature, time and other parameters through the Touchscreen controller.
2. Place the sample: Place the sample to be tested in the sample chamber.
3. Start running: Select program running or constant running mode to start the test.
4. Monitoring process: Linear dispersion and status are monitored through the observation window and controller display.
5. End the recovery: After the test, the equipment automatically returns the sample to normal temperature to avoid frost and dew condensation.
6. Data storage: Save or export test data through RS232 or USB interface.
Notice
* Ambient Temperature should be kept at 5-40 ℃, Environmental humidity ≤ 80% R.H.
* Guaranteed performance conditions are Ambient Temperature ≤ 30 ° C and no condensation.
* Safety protection including over-temperature in the studio, overpressure/overload/oil pressure in the refrigerator, short circuit/overload in the heater, overload in the blower motor and leakage protection in the system.
* Power requirements are AC380V, 50~ 60Hz, Power 10~ 15KW.
The sample chamber is left standing, and it is necessary to ensure that the sample is placed firmly during testing.
Regularly check the refrigeration system and electrical components to ensure the normal operation of the equipment.
