When operating a constant temperature and humidity test chamber, it is important to be aware of potential issues during the process and ensure proper operation. Improper handling can easily lead to equipment malfunctions. However, over time, some faults will inevitably occur. In this article, we will discuss several common faults and their solutions.
Fault: If the temperature does not reach the set value during high-temperature testing, the first step is to check the electrical system and troubleshoot each component. If the temperature in the constant temperature and humidity test chamber rises too slowly, check the air circulation system to ensure the adjustment damper is functioning properly. If the temperature rises too quickly, adjust the PID settings. If the temperature rises too quickly and triggers the over-temperature protection, the controller may be faulty; in this case, replace the control panel or solid-state relay.
Fault: If the constant temperature and humidity test chamber fails to meet the low-temperature test requirements, investigate whether the temperature drops very slowly or if it stabilizes at a certain point before rising again. If the temperature drops very slowly, check if the chamber was dried before the low-temperature test to maintain dryness. Ensure the samples are not placed too densely to prevent inadequate air circulation. After ruling out these issues, consider whether the refrigeration system is malfunctioning; in such cases, seek professional repair from the manufacturer.
Fault: If the constant temperature and humidity test chamber malfunctions during operation, with the control panel displaying a fault message and an audio alarm, the operator can refer to the troubleshooting section of the equipment's user manual to identify the type of fault. Professional maintenance personnel should then perform the necessary repairs to ensure the test proceeds smoothly. Other environmental experimental equipment will have other conditions in use, which need to be dealt with according to the current situation.
