Understanding the Technology behind High and Low Temperature Chambers

The two main functions of a high and low temperature chambers are refrigeration and heating. During the heating and cooling process, accurate, efficient, and uniform heating of various parts of the tested object is the main measurement standard of this equipment.

Due to the special nature of the test chamber work, safety protection must be carried out to ensure the smooth completion of the entire test process. Safety protection includes two aspects: the personal safety of operators and self troubleshooting and repair of equipment faults. If there are safety risks or operational errors, there will be an automatic alarm system to alert operators.

The manufacturing materials should have characteristics such as high temperature resistance, low temperature resistance, corrosion resistance, oxidation resistance, etc., and the thickness and strength should also be relatively high, making it easy to clean. The overall design should be simple and generous, with exquisite material selection and rich texture.

Only scientifically reasonable and humanized design can produce good high and low temperature test chambers. For example, there is no reaction door handle, the laboratory structure is reasonable, the shelves are easy to adjust, the display screen is simple and intelligent, the observation window is not easy to fog, and the equipment should be perforated to provide convenience for employees to operate. There is a compression device or sealing strip inside the chamber to ensure continuous insulation in the laboratory during operation.

The fan inside the chamber should be equipped with a noise reduction device to minimize the noise during the use of the test box and provide a good working environment for operators.

How to handle software and hardware issues in high and low temperature test chambers:
In the high and low temperature test chamber, there are hardware configurations for refrigeration components such as compressors and relays. Then, our users can grasp the damage situation of hardware configuration based on hearing and touch.

If it is a common fault of a refrigeration compressor, the noise of the refrigeration compressor may appear abnormal or not start, or the temperature of the refrigeration compressor itself is much higher than normal, making it difficult for users to grasp the common faults of relays and refrigeration components.

The damage to another control board and the operation of the refrigeration unit, as well as the damage to electronic components, can also cause the high and low temperature test chamber to not cool down and not cool down.

This hardware configuration also has common faults. When the kinetic energy pairing of the high and low temperature test chamber is not scientific, such as excessive installation of heating output power, and when the heating element is damaged, it will immediately lead to inconsistent cooling and heating capacity of the air conditioning. Although the cooling capacity of the air conditioner is large, its heating capacity is offset, and the heating capacity is much higher than the cooling capacity of the air conditioner, so the temperature does not seem to decrease at this time.

The key to common software faults refers to the common faults of the control board of the high and low temperature test chamber, including main internal parameters, data signals from the control point IS of the control relay, etc.

System abnormality refers to the original design concept of the refrigeration unit being not very good, and also includes the phenomenon of non cooling caused by refrigerant leakage, which is caused by transportation and the operation of high and low temperature test chambers, vibration during the entire process, or poor welding and processing technology of cold copper pipes.

Temperature Humidity Chamber | Thermal Chamber | Climate Chamber is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2), IEC60068-2-78, IEC60598-1, GB/T2423.17, GB/T5170.2, GB/T5170.5. The climate chamber is used to test the CFL/LED which meets IES LM-80-08, electricity products, automative cars, home appications and mobiles.

What is Climate Chamber?

Climate chambers is used to simulate a temperature enviromental condistions, it may also be called environmental chambers or Thermal Chamber or Temperature Chamber. You can click the below videos to learn the details and also how to operate it.
