In summer, the following points should be paid attention to when using environmental test equipment such as high and low temperature test chambers, constant temperature and humidity test chambers, thermal shock test chambers, rapid temperature change test chambers, and three comprehensive test chambers:
1. Use environment: Keep the air conditioner temperature in the surrounding environment of the test box suitable, the ventilation should be good, and there should be no obstacles blocking the heat dissipation port of the test box. If the indoor temperature is too high, an external fan can be used to assist cooling.
2. Humidity control: Humidity also has a great influence on the high-precision test work. In summer, you should pay attention to the humidity inside the test box and the physical cabinet to ensure the stability of the test box temperature.
3. Refrigeration system: The weather in summer is hot, and the temperature in the air-conditioned room is generally relatively high. It should be preheated in advance to ensure the normal working range of the refrigeration system.
4. Pay attention to safety: the test chamber will emit heat in a high-temperature state, and you need to pay attention to safety indirectly. If the test chamber is in place, the time for opening the door should not be too long, and the instrument door should not be opened too frequently.
5. Maintenance: Maintenance is the key to the use of the test chamber, so after the equipment has been in operation for a long time, it is necessary to check and maintain the equipment. Improper maintenance or faults will lead to inaccurate experimental test results. Many test chambers need to inspect or replace internal parts after several years of use to ensure stable operation of the equipment.
To sum up, the use of environmental test equipment such as high and low temperature test chambers in summer requires maintaining a suitable air-conditioning environment, paying attention to humidity control, setting refrigeration, and paying attention to safety and maintenance.
