Walk-in climate chambers play an important role in environmental testing and product development. To ensure the proper operation of the equipment and the accuracy of test results, correctly using the walk-in climate chamber is crucial. This article introduces some key usage precautions to help users avoid common problems when operating the walk-in climate chamber, improving work efficiency and safety.
Before conducting tests, make sure the door of the walk-in climate chamber is securely locked. This measure helps prevent the indoor temperature from leaking, thereby maintaining the set environmental conditions. However, before locking the door, ensure that no other operators are inside, as not all walk-in climate chambers can be opened from the inside. If the door is not securely locked, it may affect the accuracy of the test results.
During the testing process, if you need to open the door of the walk-in climate chamber for inspection or adjustment, be sure to take protective measures to avoid exposure to cold or hot air from outside. Operators also need to ensure adequate oxygen inside to avoid work efficiency reduction or safety hazards due to insufficient oxygen.
The power connection of the walk-in climate chamber must be stable to ensure the safe operation of the equipment. Before each use, carefully check the power cord and other electrical parts of the walk-in climate chamber to ensure there are no damages or abnormalities. If problems are found, they should be addressed immediately to prevent electric shock or other electrical safety hazards.
After completing low-temperature operations, it is recommended to perform drying at 60℃ for about 30 minutes before opening the door. This can avoid affecting the accuracy of subsequent tests or causing the evaporator to freeze. Ensure this type of temperature humidity control chamber is reliably grounded during operation to prevent safety risks from static induction.
During the operation of the walk-in climate chamber, avoid opening the chamber door unless absolutely necessary. Unauthorized openings may lead to the following adverse consequences:
High-temperature steam might escape, affecting the surrounding environment.
High temperatures inside the door may cause unstable test conditions.
Hot air might trigger fire alarms, causing false alarms.
Frequent switching operations might damage the compressor, affecting the equipment's lifespan.
When operating the walk-in climate chamber, ensure the wet gauze is installed correctly to obtain accurate relative humidity. During equipment operation, avoid touching the inside of the chamber with your hands to prevent electric shock or fan injuries. The maintenance and inspection of the walk-in climate chamber should be carried out by dedicated personnel, especially electrical system inspections, which should be completed by professional electricians to prevent electric shock due to uninformed personnel's mishandling.
Although the electrical parts of the walk-in climate chamber have perfect anti-electric shock measures, caution is still required during operation. Do not touch the electrical components during work to avoid electric shock accidents. During high-temperature testing, the temperature inside the walk-in climate chamber is very high. Be cautious when opening the door to prevent scalding. When the refrigerator is working, the temperature of the exhaust copper pipe is also very high, so avoid direct contact during operation.
During low-temperature tests, the temperature inside the walk-in climate chamber is extremely low. Be cautious when opening the door to avoid frostbite. The equipment power supply should use a three-phase five-wire system, and the cable should be four-core, including three-phase lines and a neutral line. Ensure safe power connections, and do not use the walk-in climate chamber in flammable, explosive, strong magnetic field, or strongly vibrating environments. It is not advisable to move or repair the equipment during power-on or operation to ensure safety.
In summary, correct use of the walk-in climate chamber not only improves the accuracy of test results but also ensures the safety of the operators. By following the above precautions, you can better utilize the functions of the walk-in climate chamber and achieve the desired testing effect.
