Do You Really Know About Constant Temperature And Humidity Test Chamber

With the development of The Times and the progress of science and technology, people have higher and higher requirements for the environment of industrial production, and the application field of temperature and humidity control equipment is more and more extensive. Constant temperature and humidity test chamber is a kind of test equipment that can simulate the temperature and humidity under different environmental conditions. It is mainly used for product performance testing in electronic appliances, aerospace, automotive, medical instruments and other industries to assess the reliability and durability of products in different environments.

Working principle of constant temperature and humidity climate chamber

Climate chambers create specific climate conditions by controlling parameters such as air temperature, humidity and flow speed. Specifically, the constant temperature and humidity climate chamber is usually composed of the following parts

Heaters and refrigerators

Used to control air temperature. Heaters and refrigerators can control temperature by controlling the flow of current or refrigerant.

Humidifier and dehumidifier

used to control air humidity. Humidifiers increase air humidity by spraying water vapor, while dehumidifiers reduce air humidity by condensing water vapor.

Air circulation and filtration systems

Used to ensure the flow and quality of air. Air circulation systems can be implemented by fans or fans to ensure uniform air flow throughout the climate room. The filter system can clean the air through the filter to prevent dust, pollutants and microorganisms from affecting the test results.

Control system

Used to monitor and control temperature, humidity and air flow speed and other parameters. The control system is usually composed of sensors, controllers and actuators, which can automatically adjust the climate parameters in the climate test chamber to maintain a constant temperature and humidity condition.

When using the constant temperature and humidity climate chamber, the user can set the required temperature and humidity range according to the need, the climate chambers will automatically control the environmental parameters, to maintain a constant climate conditions. In this way, users can conduct various tests and experiments in a controlled environment to evaluate the performance and stability of products or equipment under different climatic conditions, thus guiding product development and production.

Application field of constant temperature and humidity climate chamber

Electronic products testing

Temperature and humidity control test chamber can be used to test the performance and reliability of electronic products in different temperature and humidity conditions, such as mobile phones, computers and other electronic products of high temperature resistance, humidity resistance and other performance testing.

Material performance test

Simulate various climatic conditions, used to test the performance and stability of materials in different temperature and humidity conditions, such as metal, plastic, rubber and other materials weatherability test.

Medical product testing

the environmental climate chamber can simulate the temperature and humidity conditions in the human body, and is used to test the performance and stability of medical products in different climatic conditions, such as stability testing of drugs and instruments.

Agricultural science and technology

 Climate testing chamber can simulate different seasons and climate conditions, used to study the growth and yield performance of various crops under different climate conditions, such as the growth test of vegetables, fruits, etc.

Aerospace

 Used to test the adaptability and performance of aerospace equipment in different climatic conditions, such as hot chamber tests of aircraft, satellites, etc.
Automobile industry: Used to test the performance and durability of auto parts in different weather conditions, such as brake system, engine, high temperature resistance, humidity resistance and other tests.
In short, temperature and humidity control chamber plays an important role in various fields, providing important technical support for product development, production and quality control.

Maintenance and maintenance of constant temperature and humidity test chamber

First of all, the internal impurities should be removed before running the constant temperature and humidity test chamber. The distribution room should be cleaned at least once a year. When cleaning, use a vacuum cleaner to remove indoor dust. Also wash the outside of the body once * more than once. Wipe with soap and water before cleaning.

The second is the humidifier inspection and maintenance. The water stored in the humidifier should be replaced once a month to ensure clean water. The humidifying disk should be cleaned once a month to ensure smooth water flow. In addition, pay attention to the constant temperature and humidity climate chamber test cloth replacement. When the surface of the test cloth becomes dirty or hard, or after the temperature control is completed, the test cloth must be replaced before the temperature and humidity sphericity control can continue. The test cloth should be replaced once every three months, when replacing the temperature measuring body with a clean cloth, the test cloth should be cleaned before replacement.
 
After that, we should emphasize the inspection and adjustment of the water level of the floating ball in the constant temperature and humidity chambers. The water level of the water tank should not be too high, so as not to overflow the water tank or too low, so that the wet ball test cloth absorbs water abnormally, affecting the accuracy of the wet ball. Just keep it a full six. The water level of the tank can be adjusted to adjust the height of the tank.
 
Constant temperature and humidity test chamber condenser dust removal: condenser should be regularly maintained on a monthly basis. Use a vacuum cleaner to remove the dust attached to the condenser cooling net or spray the dust with high pressure air.
