Constant Temperature And Humidity Chamber

1. Poor air circulation

Poor air circulation inside the test box will affect the distribution of moisture, resulting in uneven humidity. The test box has poor sealing, which causes poor air circulation and prevents humidity from rising. The moisture-proof plate, sealing strips, and elastic contact parts contribute to this issue.

2. Monitoring control system failure

The test box humidity setting is inaccurate, or humidity sensor failure, monitoring, control software failure, etc., may lead to the test box humidity not going up. This is because when the monitoring and control system fails, the humidity inside the test box can not be monitored and adjusted in a timely manner.

3. Removal of incomplete reasons

If there is dust, moisture, or other contaminants in the test box, it will affect air circulation. This situation can lead to uneven humidity, preventing humidity from increasing. To prevent this, clean the test box promptly to maintain a clean and dry internal environment.

4. Humidifier failure

Test box humidifier failure, or humidifier and control system mismatch, will also lead to the test box humidity does not go up. Humidifier failure refers to the humidifier sensor, sprayer, and other parts being damaged or aging, so you need to contact the supplier to overhaul or replace the humidifier.

5. The ambient temperature is too low.

The ambient temperature of the test chamber is too low, which will also affect the rise of humidity. When the temperature difference between the inside and outside of the test box is too large, it will lead to insufficient atmospheric humidity, thus affecting the rise in humidity. At this time, it is necessary to increase the temperature inside the test box to enhance the rate of rise in humidity.

1. High-temperature Test:

   The test chamber can test high temperatures up to 150 °C. If you need higher temperatures, customization is available upon request. This chamber is mainly used to assess how electronic products withstand high temperatures.

2. Low-temperature Test:

   It can also perform low-temperature tests, capable of reaching minus 70 °C. If you need lower temperature testing, please contact the editor for customization!

3. Humidity Test:

   The programmable constant temperature and humidity test chamber can conduct humidity tests. It can simulate humid climates, with the standard humidity range between 20% and 98% RH.

4. Constant Temperature and Humidity Test:

   This chamber can carry out constant temperature and humidity tests, including high-temperature/high-humidity and low-temperature/low-humidity scenarios. A common example is the Double 85 test, where the chamber is set to 85°C with 85% humidity conditions to assess the reliability of test samples.

5. Hot and Humid Test:

   It can do hot and humid test (alternating hot and humid test, also known as the hot and humid test,) that is to simulate the harsh environmental climate of spring, summer, autumn and winter to test the product is resistant to complex and abnormal changes in the climate, if a long time in such an environment, the product needs to have sufficient resistance to alternating hot and humid capabilities.

6. Other Tests:

Issue Analysis:

1. Compressor Water Ingestion Causes
   When ice blockage occurs in the constant temperature and humidity test chamber, the technician suggests addressing the heating element’s susceptibility to blockage. This involves releasing fluorine, purging nitrogen-filled drying lines, and re-pumping fluorine. If ice blockages persist, it’s likely due to incomplete evacuation or excess fluorine-contaminated water. Notably, many of these failures stem from the compressor drawing in water.
2. Chamber Sealing Problem:
   Inadequate sealing of the constant temperature and humidity test chamber liner allows a significant amount of airborne water to penetrate the insulation layer. Leakage occurs during refrigerant leakage events. Prolonged operation without compressor shutdown results in negative pressure on the equipment’s low-pressure side, causing substantial water suction into the compressor through leakage points and leading to recurrent ice blockages.

Solution:

Method 1: Carefully apply heat to the compressor and evaporator using an electric stove or light bulb. This facilitates the evaporation of water within the compressor and the system. Subsequently, use a vacuum pump to remove the water along with the air.
Method 2: Weld opens the high-pressure pipe and filters the drier. Allow the compressor to idle 2 to 3 times, utilizing the temperature rise of the compressor to evaporate and discharge water. Each idle session should be around four hours to prevent compressor damage.

⑥ Bad heat dissipation, the use of equipment at the site to install the appropriate power of the air conditioning cooling or open the doors and windows so that the air can circulate

1. First, its direct evaporative cooler surface frost or ice conditions, thus increasing the heat transfer thermal resistance to affect the heat transfer effect, thus making the evaporation temperature gradually reduced so that the evaporation pressure is reduced.
2. Second, in the constant temperature and humidity test chamber of the refrigeration system is a dirty blockage, and especially for the Freon system, and because of the dirt will make the filter drier and the finer piping clogged, so the system will exist in the water to affect the expansion valve to produce the phenomenon of ice blockage.
