The constant temperature and humidity test chamber is constructed with a robust shell design. It employs an imported digital display instrument for precise control of both temperature and humidity, as well as for clear readings of these parameters. The interior of the chamber features high-grade, mirror-polished 304 stainless steel, while the exterior is coated with electrostatic spray paint for enhanced durability. The insulation layer is highly efficient, utilizing a steam-based humidification method, and includes an automatic water circulation system and replenishment function. This ensures ease of use and reliable performance.
The refrigeration system of the test chamber uses a top-tier, closed air-cooled compressor for optimal cooling efficiency. Standard models range in size from 1 cubic meter up to 100 cubic meters. However, if larger, non-standard sizes are required, custom solutions can be tailored to meet specific customer needs. There are numerous success stories showcasing our ability to deliver such bespoke equipment.
For instance, in the electronics sector, circuit boards can undergo rigorous testing within this chamber. They might be subjected to high temperatures of up to 150 degrees Celsius for heat resistance testing or cooled down to 0 degrees Celsius for cold stress evaluation. Specific temperature and humidity settings can also mimic humid conditions, helping assess how environmental factors impact the board's functionality and reliability. This helps determine if the board meets quality standards and is suitable for real-world applications.
When operating the constant temperature and humidity test chamber, several precautions should be taken into account:
Firstly, after completing a low-temperature test cycle, it is advisable to run a drying process at 60°C for approximately 30 minutes before opening the chamber door. This prevents any potential issues that could arise from prolonged freezing of the evaporator or affect future measurements.
Secondly, avoid opening the chamber door unnecessarily during operation unless absolutely essential. Doing so could lead to several undesirable outcomes including the sudden release of hot, humid air, leaving residual high temperatures inside the chamber, triggering false alarms, or damaging the compressor. Frequent door switches are discouraged except when specifically required by the test protocol.
Thirdly, ensure proper grounding of the chamber to eliminate risks associated with static electricity buildup. Additionally, regularly inspect circuit breakers and over-temperature protection devices to safeguard both the equipment and operators. Personal protective gear should always be worn by users handling the machinery.
Fourthly, correctly positioning the wet bulb wick is crucial for accurate humidity readings. While the chamber is active, keep hands away from it to avoid accidental shocks or injuries caused by moving parts like fans.
Lastly, unauthorized personnel should refrain from attempting repairs or inspections. Only authorized technicians, preferably accompanied by certified electricians and circuit specialists, should conduct maintenance activities. This minimizes risks of electrical hazards due to lack of knowledge or improper handling.
By adhering to these guidelines, the constant temperature and humidity test chamber can provide reliable and safe service, ensuring consistent and accurate results across various industrial applications.
