What is a Test Chamber and How Does It Work?

  • December 29, 2021

    The health industry, consumer goods industry, construction industry and many others have to evaluate the materials they use for various purposes. One of the ways to do that is with the help of a test chamber.Get more news about Cab Test Chamber,you can vist our website!

    Specific products have to resist external factors to prove functional and useful and therefore need to pass a series of tests. In this article, we’ll explain what a test chamber is and how it works.

    What is a Test Chamber?
    A test chamber, an environmental chamber or a climatic chamber is a type of enclosure that mimics the effects of environmental conditions. Experts in the industry use it to see how their products, materials or components can withstand harsh conditions before going into large-scale production.

    They use the chamber for some other purposes, such as:

    preparation for additional tests on products
    stand-alone tests for different material combinations.
    How a Test Chamber Works
    If you want to understand how a test chamber works, it’s essential to understand two physical parameters: temperature and humidity.
    Temperature control is the first factor for the functionality of a test chamber. The chamber has to perform two tasks: heating and cooling. Moreover, the temperature has to distribute through space inside of the chamber evenly.

    Unique technical settings make it easier for the air to circulate within the compartment, regardless of the item that’s put to the test. The chamber also has a closed circuit mechanical cooling scheme with the following elements:The second parameter, humidity, allows for an equal distribution of moisture within the compartment. However, for the chamber to do its job, the system must perform both humidification and dehumidification.

    An electric humidifier lets the steam into the chamber when there’s a hole in the air flow. A special algorithm controls the humidifier for optimized performance.

    Dehumidification, on the other hand, is done by a mechanical system. Once you expose an object with a lower temperature to a different setting (higher temperature), the surface of the object becomes moist because of the condenzation process.

    An evaporator then lowers the humidity inside the chamber since it has the lowest temperature. It turns on only when you have to take out the excess moisture from the compartment.
