FAQ:

1. Under extreme temperature and humidity conditions, such as when approaching the extreme values of the equipment's temperature and humidity, how can the stability and accuracy of the temperature and humidity control algorithm be ensured? What unique control strategies does the equipment adopt to avoid overshoot or undershoot phenomena caused by large fluctuations in temperature and humidity?

Our equipment uses an adaptive fuzzy PID control algorithm. This algorithm can automatically adjust control parameters based on the real - time changes in temperature and humidity and their deviations from the set values. When approaching the extreme values of temperature and humidity, the algorithm will intelligently reduce the adjustment intensity to avoid overshoot caused by excessive adjustment. At the same time, through high - precision sensor feedback and a fast data processing system, the changes in temperature and humidity can be monitored in real - time. Once an undershoot trend appears, the adjustment intensity will be immediately increased to ensure stable and accurate temperature and humidity control under extreme conditions.

2. When the refrigeration and heating systems and the humidification and dehumidification systems of the equipment work in coordination, how can efficient energy utilization and precise energy distribution be achieved? Is there an intelligent energy management mechanism to reduce energy consumption?

The test chamber is equipped with an intelligent energy management system. When the refrigeration and heating systems and the humidification and dehumidification systems work in coordination, this system will dynamically adjust the power output of each system according to the current temperature and humidity requirements and the operating status of the equipment. For example, when heating and needing to increase humidity, the system will give priority to using the waste heat generated during the heating process for humidification, improving energy utilization. At the same time, by optimizing the start - up and shutdown sequences of each system, unnecessary energy losses are avoided, achieving efficient and precise energy distribution, reducing energy consumption while ensuring the test effect.

3. As the industry's requirements for product reliability testing continue to increase, new testing standards and specifications are constantly being introduced. How can this constant temperature and humidity test chamber ensure rapid adaptation to these changes, especially in relation to complex temperature and humidity cycle curves and special environmental simulations?

We have a professional R & D team that continuously monitors updates to industry standards. The control system of the equipment adopts an open - architecture, which can be easily adapted to new testing standards through software upgrades. For complex temperature and humidity cycle curves, users can use the equipment's built - in programming function to customize and edit cycle steps and parameters. For special environmental simulations, such as the comprehensive simulation of high - altitude low - pressure and temperature and humidity, we can provide customized hardware expansion modules according to customer needs to ensure that the equipment always meets the cutting - edge testing requirements of the industry.

4. In the reliability testing of chips in the electronics industry, there are strict requirements for rapid changes in temperature and humidity and long - term stable maintenance. How can this test chamber meet the requirements of rapid temperature and humidity changes while ensuring a low drift rate during long - term stable operation to meet the high - precision needs of chip testing?

The equipment adopts a dual - refrigeration system and high - precision heating elements, as well as advanced constant - current humidification and condensation dehumidification technologies. During rapid temperature and humidity changes, the dual - refrigeration system can respond quickly to achieve rapid cooling, and the efficient heating elements ensure rapid heating. During long - term stable operation, high - precision sensors and a stable control system will monitor and fine - tune the temperature and humidity in real - time, controlling the drift rate to an extremely low level. For example, the temperature drift rate can be controlled within ±0.1℃/24h, and the humidity drift rate can be controlled within ±1%RH/24h, meeting the extremely high - precision application scenarios such as chip testing.

5. When multiple groups of samples of different materials are tested simultaneously, different samples may have different impacts on the temperature and humidity environment inside the chamber. How can the equipment ensure the consistency of the temperature and humidity environment for each sample and avoid mutual interference between samples?

The interior of the test chamber adopts a partition - independent control technology. Each area is equipped with independent temperature and humidity sensors and micro - controllers. When multiple groups of samples of different materials are tested simultaneously, the system will accurately adjust the temperature and humidity of each area respectively according to the data fed back by the sensors in each area. At the same time, the unique air duct design can ensure uniform air circulation in each area, reducing environmental unevenness caused by differences in sample heat dissipation and moisture dissipation, ensuring that each sample is in a consistent temperature and humidity environment.
