What is an Aging Room?

An aging room is a large‑scale environmental test equipment.

It is a type of test chamber designed for mass production and large‑scale reliability testing. Due to its high cost, proper daily maintenance is extremely important — correct routine maintenance can effectively extend its service life.Its maintenance methods are similar to those of general environmental test chambers, and optimal performance can be maintained through regular inspection and upkeep. The following key points are provided for reference.

1. Establish operation and maintenance records

Create operation documents for easy maintenance management.Records should include:

• System startup date and time

• Test type

• Ambient temperature settings

• Detailed description of any fault symptoms when system failures occur

• Full details of all system maintenance and repair work

2. Regular operation and reasonable switching

Long‑term shutdown will shorten the service life of the system.

• Power on and run the system at least once every 10 days.

• Avoid repeated startup and shutdown in a short period: limit startups to fewer than 5 times per hour, with each shutdown interval longer than 3 minutes.

• Do not open the door of walk‑in aging rooms under low‑temperature conditions, to avoid damaging the door sealing strip.

• 

3. Dedicated operation and standardized procedures

Operation and maintenance must be performed by authorized personnel only.Strictly follow the system operating procedures to prevent unauthorized or improper operation.

4. Protect the main cabinet body

During use, avoid strong impact from sharp or blunt objects on the main housing to prevent deformation and damage.

5. Monthly test of main power switch (earth leakage circuit breaker)

Regularly test the main power switch to ensure it provides proper load capacity and leakage protection.Procedure:

• Confirm the main power switch is ON (system powered up).

• Press the TEST button.

• If the breaker trips and the operating lever drops, the function is normal.

6. Do not arbitrarily adjust leakage protection settings

The leakage, overload, and short‑circuit protection characteristics of the aging room’s leakage circuit breaker are factory‑set.Do not adjust them arbitrarily, as this may impair performance.If the breaker trips due to a short circuit, inspect the contacts. Repair or replace them if burned or dented.

7. Maintain cooling water system

To ensure normal and clean cooling water supply:

• Clean the chiller cooling water filter approximately every 30 days.

• Clean the cooling water tower once a month.

• If local air quality is poor with high dust levels, clean the cooling tower reservoir about every 7 days.

8. Test over‑temperature protector

Perform an over‑temperature protection function test:

• Set the over‑temperature protector to a temperature lower than the chamber’s actual temperature.

• If an E0.0 alarm and buzzer sound occur, the function is normal.

• After testing, reset the temperature protection setpoint appropriately to avoid unwanted interruptions.

9. Maintain air circulation

To avoid obstructing airflow, keep test products placed in the aging room at a proper distance from the air intake and outlet of the air conditioning duct.

10. Regular cleaning

• Clean dust from the electrical control room and water circuit room once a year using a vacuum cleaner.

• Wipe dry the water tray of air‑cooled chiller units with a dry cloth once a month.
