Operation manual of constant temperature and humidity chamber
The constant temperature and humidity test chamber, also known as the constant temperature and humidity test machine, or programmable heat and humidity test chamber, is used to test heat resistance, cold resistance, dry resistance, and moisture resistance of materials under a variety of environments. Constant temperature and humidity test chamber simulate high and low temperature, hot and humid environment for testing the performance of instrumentation, electronics, parts, and various materials in storage, and transportation when they are in an environment with high humidity and temperature or low humidity and temperature. Meanwhile, it is reliable testing equipment for quality control engineering.
Selection principles of the constant temperature and humidity chamber
For every environmental or reliability test, there are some strict regulations on the category of environmental factors, value, and tolerance. Moreover, environmental factors which are not needed in the test should be prevented from the test for providing the exact evidence to analyze the product failure and failure mode. As a result, the test product is only allowed to be put in the specified environment instead of any other environmental stress interference.
Environmental test equipment may carry out multiple tests of the same type of product while an engineering product under test may be put into different environmental test equipment for testing. The environmental conditions created by the environmental test equipment are required to be repeatable in order to ensure the test results are comparable which are all about the same product in the same test specification under the specified environmental test conditions.
A constant temperature and humidity chamber must accurately or similarly simulate the process of the use, storage, shipping, and other aspects of engineering products. Additionally, it must satisfy the demands of the uniformity of the temperature field and the accuracy of the temperature control in accordance with defined test specifications, requirements of test value for high temperature and low temperature, and the time of test which are specified by various types of products. We can guarantee a precise reproduction of environmental conditions in the environmental test only by doing this.
Safety and reliability
The test cycle of environmental testing, especially reliability testing, is long. Sometimes, the machine will test military products with a very high value. In the test process, the testers need to carry out the operation or test around the scene. Therefore, the environmental test equipment is required to be characterized by safe and easy operation, reliable use， long working life, and so on for the normal operation of the experiment.
Measurability and controllability
The environmental conditions provided by any environmental condition must be observable and controllable, which is not only set to limit environmental parameters to a certain tolerance range, but also for the safety of the experiment in order to eliminate the unnecessary loss caused by the uncontrolled environmental condition.
Here are some regulations for the place where the constant temperature and humidity chamber is installed to facilitate the heat dissipation and maintenance of the box.
There should be 300mm between it and the nearby wall or object.
We should identify a location where the average annual temperature ranges from 15 to 35 °C and the relative humidity reach more than 85%.
There should not be a sharp change in the ambient temperature of the installation place.
It should be mounted on a smooth surface (when installing, we should confirm that it is placed horizontally by using the level).
It ought to be set up in an area with minimum dust, good ventilation, freedom from combustible or explosive items, high-temperature heat sources, or without direct sunshine.
As much as possible, it should be installed close to the power source.
How to deal with the high-pressure alarm of the temperature and humidity test chamber?
1, Check whether the site ambient temperature is too high. If the site temperature is above 30 ℃, open doors and windows or exhaust system ventilation, open air conditioning to reduce the ambient temperature;
2, Ensure that the distance between the environmental box and other objects (or walls) is greater than 60 cm for better heat dissipation. (If the air is exhausted upwards, it is necessary to install an exhaust pipe to direct the hot air outdoors.)
3, Check whether the compressor is at normal pressure value. (If the pressure is too high, discharge part of the refrigerant to make it reach the normal pressure value.)
4, Check whether the condenser is dirty and blocked. If the condenser is dirty and blocked, it will easily absorb dust and impurities, which will affect the ventilation and heat dissipation, and the condenser should be cleaned up.
5, Check whether the condensing fan is running normally. If the condensing fan is damaged and affects the wind circulation, the condensing fan should be replaced.
