1. Introduction

2. Key Features

2.1 Exceptional Temperature and Humidity Simulation Precision

• Ultra-wide Temperature Range Coverage: The test chamber can achieve an ultra-wide temperature adjustment range from - 60°C to 180°C. This means that it can not only simulate the extremely cold temperatures in the Arctic Circle, subjecting automotive components such as batteries and rubber seals to performance tests in near-extreme low temperatures to ensure their normal operation in cold regions but also simulate the high-temperature environment in the engine compartment. The temperature of up to 180°C can be used to test the heat resistance of components around the engine, such as the stability of plastic intake manifolds and electronic sensors at high temperatures. The temperature control accuracy can reach ±0.3°C, providing a solid guarantee for precise testing.
• High-precision Humidity Regulation: The humidity adjustment range is between 10%RH and 98%RH, with an accuracy control of ±2%RH. In a high-humidity environment, it can simulate the rainy and humid seasons in southern China or the humid climate in coastal areas to detect the anti-corrosion ability of automotive metal components and the moisture-proof performance of electronic devices. The low-humidity environment can simulate the dry climate in desert areas to test the anti-cracking performance of interior materials and the stability of some electronic components sensitive to humidity.

2.2 Highly Flexible Programming Functions

• Construction of Complex Temperature and Humidity Curves: With the help of the advanced programming interface, users can easily construct complex temperature and humidity change curves according to actual needs. For example, simulate the dynamic changes in battery temperature and interior humidity of an electric vehicle under different driving modes. During the fast charging mode, the battery temperature rises rapidly, and at the same time, the operation of the vehicle's air conditioning system changes the humidity. By setting the heating and cooling rates as well as the humidity change rate, this process can be precisely simulated, providing data support for the optimization of the battery thermal management system and the vehicle interior environment control system.
• Multi-stage and Multi-scenario Test Programs: It supports the creation of multi-stage test programs, and each stage can be set with different temperature and humidity parameters, durations, and change rates. For example, for the durability test of automotive parts, a test program including multiple stages such as high-temperature and high-humidity accelerated aging, low-temperature cold start, and rapid temperature and humidity alternation can be designed to simulate various environmental scenarios that the parts may encounter throughout the vehicle's life cycle and comprehensively evaluate their performance changes.

2.3 Innovative Structure and Intelligent Safety Protection

• Optimized Internal Structure Design: The test chamber adopts an innovative air duct design and internal layout to ensure uniform distribution of temperature and humidity inside the chamber. The unique circulating air duct, combined with an efficient fan, enables the temperature and humidity uniformity to reach ±2°C (temperature) and ±5%RH (humidity) when the chamber is unloaded, and it can also maintain a minimal deviation range when loaded, avoiding inaccurate test results caused by local environmental differences. At the same time, the internal space is flexibly designed, and special sample racks and fixing devices can be customized according to the size and shape of automotive parts to ensure that the test samples are fully and evenly exposed to the temperature and humidity environment.
• Intelligent Multiple Safety Protection System: It is equipped with an intelligent multiple safety protection device, including multiple protections such as over-temperature, over-pressure, leakage, and water shortage. When the temperature exceeds the set upper or lower limit by a certain threshold, the over-temperature protection system will be activated immediately, cutting off the heating or cooling power supply and triggering the alarm device. The over-pressure protection can prevent damage to the equipment caused by abnormal pressure. The leakage protection can ensure the safety of the operators. The water shortage protection ensures the normal operation of the humidification system. In addition, it also has an intelligent door lock and door opening warning function. When the test is running, if someone tries to open the door, the system will issue an alarm and prevent the door from opening to prevent the temperature and humidity from getting out of control and the test samples from being damaged.
