Introduction to environmental chamber:
An environmental chamber is an enclosed space where environmental conditions such as temperature and humidity can be controlled.
Some chambers can also simulate corrosion by introducing salt spray into the chamber.
The dimensions of these chambers can vary greatly depending on the type of product that needs to be tested.
Sizes range from 20 liters to 400,000 liters, enough to test an entire truck!
What is a climate chamber used for?
The main function of the environmental testing chamber is to test the behavior of the products we use every day under extreme climatic conditions.
For example, a car that runs well in a dry climate may not run well in a high-humidity environment.
Environmental chambers allow manufacturers to stress test their products in a single environment.
The environmental chamber allows testing of products in continental climates with cold winters and hot summers, as well as in Mediterranean climates with higher temperatures.
If properly calibrated, environmental chambers can produce reliable results that simulate how a product will perform during its actual life cycle.
Proper calibration of the test chamber is critical to obtaining reliable results.
Various test chambers have different calibration procedures depending on how the environmental chamber works and the area in which the chamber is used, so before starting the calibration process it is necessary to contact the chamber manufacturer to find out the correct procedure.
How do environmental chambers work?
Environmental chambers work on the principle that all conditions can be managed manually through various mechanical processes.
The temperature is controlled by an electric heater to heat or a refrigeration unit to cool the chamber.
For example, to simulate the corrosive effects of seawater, researchers sprayed a salt solution through nozzles in the chamber, creating a fine mist that covered the entire product.
Humidity in the test chamber can be simulated in two different ways: evaporating water via a heat source or ultrasonic technology.
"Water vapor is usually introduced into the test chamber through a steam generator, which heats the water and produces steam. This steam rises to the top of the environmental chamber where it cools again, increasing the overall humidity in the test chamber. This method is useful, Because it can create high humidity fairly quickly in a large room.
