Why is the constant Temperature Humidity Chamber blocked

Why is the constant temperature humidity chamber blocked?
1. During the test, the door was opened, and there was icing in the working room.
2. The dryer is aging and fails, and the drying and water absorption function is lost.
3. When the cryogenic compressor is pressurized for leak test, the water in the air is condensed into water droplets and injected into the pipeline, resulting in ice blockage.
4. Too much water in the refrigerant will cause ice blockage.
5. After the refrigeration evaporator is damaged, it is still in the startup state for a long time, which brings the moisture in the cold room and the moisture in the air into the compressor together, resulting in ice blockage.

6. The process pipe of the constant temperature humidity chamber is sealed after being opened, and it is not handled in time. In addition, the water in the air will be brought into the machine from the gate when the machine is occasionally turned on. There are also compressors that have not been sealed and have been placed for a long time and are put on ice and frost without drying treatment, which will also cause ice blockage.

Special precautions in the operation of constant temperature humidity chamber:
1. In order to prevent electric shock or misoperation and fault, please do not connect the power supply before installation and wiring.
2. Check whether the power supply is stable before starting.
3. To avoid machine failure in the constant temperature humidity chamber, please provide power supply within the rated voltage range.
4. In order to prevent electric shock or misoperation and fault, please do not connect the power supply before installation and wiring.
5. Please note that the machine must be grounded safely and reliably to avoid electrostatic induction.

What is the maintenance of constant temperature humidity chamber? Professional maintenance shall be carried out every year.
1. Clean the water circulation system, clean the water filter, replace the filter screen, check the operation of the water pump, including whether the water flow switch acts well, adjust the water circulation flow, and test the operation.
2. Replace the fresh air filter screen.
3. Check all electrical circuits and components to ensure reliable operation and good contact.
4. Replenish refrigerant according to working conditions: check whether the system refrigerant needs to be replenished to ensure effective cooling power.
5. Refrigeration system cleaning: replace the refrigerant oil and clean the oil filter screen.
6. Inspection of vulnerable parts of refrigeration system: check the sealing condition of compressor and connecting components, and replace all filters.
7. Leakage inspection of refrigeration system: check all connecting parts of refrigeration system and valve plate for leakage and tighten them.
8. Comprehensive operation of the system: check whether all running parts are in good condition.

Daily maintenance of high and low temperature test chamber:
1. Water circuit and humidifier cleaning: if the water circuit is not smooth and the humidifier is prone to scale, the humidifier will be damaged by dry burning, so the water circuit and humidifier should be cleaned frequently.
2. Adhere to setting the temperature close to the ambient temperature after each test, cut off the power supply and clean the inner wall of the workshop after working for about 30 minutes.
3. If the machine is not used for a long time, the product shall be powered on regularly every half month, and the power-on time shall not be less than 1 hour.

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.
