What are the precautions for using a thermal shock Test Chamber?

Abstract: 文章《使用冷热冲击试验箱有哪些注意事项?》提供了操作冷热冲击试验箱时的重要注意事项。首先,应避免试验箱频繁启停,以减少对制冷系统的机械负荷,并延长设备寿命。严禁测试易燃、易爆、易挥发或腐蚀性物质,以免造成事故和设备损坏。测试对象的放置要确保不影响气流平衡,且总面积应小于工作室横截面面积的1/3。在操作前需确保试验室门紧闭,以防气体泄漏。操作过程中避免直接触摸机器部件,以防触电或事故。低温试验时应尽量避免开门,以防蒸发器和制冷系统结霜。完成低温试验后,应将温度设定为30℃进行干燥处理。高温高湿条件下,严禁开门以防烧伤、烫伤或引发火警。

1. Try to avoid frequent start and stop of the thermal shock test room (try not to restart the operation within 5 minutes after the stop of the thermal shock test room), so as not to increase the mechanical load of the refrigeration system compressor and affect the service life of the unit.

2. It is strictly forbidden to test flammable, explosive, volatile, and corrosive substances in the thermal shock Test Chamber indoors, otherwise it will cause accidents, damage the machine, and invalidate the test results.

3. The placement of the test object should not affect the airflow balance and the test equipment in the environment. Otherwise, it will affect the performance of the thermal shock Test Chamber and the accuracy of the test. On any cross-section perpendicular to the wind direction of the internal circulating airflow, the total area of the test object shall not be greater than 1/3 of the cross-sectional area of the working chamber.

4. The door of the test room must be closed tightly before operation, otherwise it will cause gas leakage in the work room, and the test does not meet the performance requirements.

5. During the operation of the thermal shock Test Chamber , please do not touch and check the system components of the machine with your hands to avoid accidents such as electric shock or motor impact. So please stop the machine and turn off the power before repairing.

6. If the thermal shock Test Chamber operates below 0 ℃ during the low temperature test, try to avoid opening the Test Chamber door, because opening the Test Chamber door during the low temperature test will easily cause frosting on the evaporator and other components of the refrigeration system. The lower the test temperature, the more serious the effect. If it is necessary to open the door, the opening time should be shortened as much as possible.

7. After using the thermal shock Test Chamber to complete the low temperature test operation, the test temperature condition should be set to 30 ℃, and dry for about half an hour (return to normal temperature, the thermostat can be set to automatic function), then close and open the test box. After the temperature returns to room temperature, the test products can be picked and placed so as not to affect the test performance.

8. When the thermal shock Test Chamber is operating under high temperature and high humidity conditions, it is strictly forbidden to open the door, otherwise it may cause the following adverse consequences:

(1) The high-temperature and high-humidity gas rushes out of the high-Temperature Test Chamber sharply, which may easily cause burns;

(2) The inside of the door, the test area and the surface of the sample are still at high temperature, which is easy to burn your hands;

(3) High temperature air may trigger a fire alarm and cause malfunction.
