Troubleshooting for Some Problems during Application

Climate explains some frequent questions of temperature and humidity chamber during application:.
First, the constant temperature and humidity test chamber in the course of a sudden test failure, the control instrument appears on the corresponding fault display prompts and voice alarm tips. The operator can quickly check out which type of failure is in the chapter on the troubleshooting of the operation of the device. The operator can quickly troubleshoot to ensure that the test is performed normally. Other environmental testing equipment in use there will be other phenomena, it is necessary to specific phenomena, specific analysis and exclusion.
Second, in the high temperature test, such as temperature changes can not reach the test temperature value, you can check the electrical system, one by one troubleshooting. Such as constant temperature and humidity chamber temperature is very slow, it is necessary to view the wind circulation system, look at the wind circulation adjustment baffle is open normally, on the contrary, check the wind cycle motor running is normal. Such as the temperature overshoot so you need to set the PID set parameters. If the temperature rises directly, then the controller fails to replace the control instrument.
Third, the constant temperature and humidity test chamber in the hot and humid test, the actual humidity will reach 100% or the actual humidity and the target humidity difference is very large, the value is much lower, the former phenomenon: the wet bulb sensor may be caused by drying, It is necessary to check the wet bulb sensor water tank is water, the water level in the tank is controlled by a water level controller, check the water level controller water supply system is normal water supply, water level controller is working properly. Another may be the wet ball gauze due to the use of a long time, or water quality purity of the reasons, will make the gauze hard, so that gauze can not absorb moisture and dry, as long as the replacement or cleaning gauze can rule out the above phenomenon. The latter phenomenon is mainly the constant temperature and humidity chamber humidification system does not work, check the humidification system of water supply system, water supply system, whether there is a certain amount of water to control the humidifier boiler water level control is normal, humidification boiler water level is normal The If everything is normal, it is necessary to check the electrical control system, which requires professional maintenance personnel to repair.
Fourth, constant temperature and humidity test chamber low temperature can not reach the test indicators, then you have to observe the temperature changes, it is clear that the temperature drop is very slow, or the temperature to a certain value after the temperature has rebounded. The former will check whether to do before the low temperature test studio drying, so that the studio to keep dry after the test sample into the studio to do the test, the studio test sample is placed too much, so that the studio The wind can not be fully circulated, in the exclusion of the above reasons, we must consider whether the refrigeration system failure, and this will ask the manufacturers of professionals to repair. The latter phenomenon is the use of constant temperature and humidity chamber equipment, such as the environment is not good, the device placed in the ambient temperature, place (the distance between the box and the wall) to meet the requirements (in the equipment operating instructions are provided ).
