Car Testing Climate Test Chamber Meets ISO 16750-4 Standard

1. Product Name and Purpose

2. Product Features

• Robust and Automotive-Grade Construction
  • The chamber is constructed with a heavy-duty framework, typically fabricated from high-strength alloy steel, to withstand the rigors of testing full-sized vehicles and heavy automotive components. The exterior is engineered to be highly durable and resistant to corrosion, ensuring its integrity even after prolonged exposure to harsh weather conditions. The interior is lined with a refractory material that can endure rapid and extreme temperature changes without compromising the testing environment. The door is designed with a reliable sealing mechanism, incorporating a high-quality gasket and a multi-point locking system, ensuring an airtight enclosure. It also features a large viewing window made of toughened, heat-resistant glass, allowing for visual inspection of the testing process while maintaining the chamber's environmental integrity.
• Precision Climate Control Systems
  • Temperature Control: Capable of maintaining a wide temperature range, from -40°C to +85°C, with an outstanding accuracy of ±0.5°C. It utilizes advanced refrigeration and heating technologies, such as cascade refrigeration for extreme cold applications and high-power heating elements for rapid temperature elevation. The control system incorporates a sophisticated feedback loop, with multiple temperature sensors strategically placed throughout the chamber, ensuring uniform temperature distribution and minimal temperature gradients. The user-friendly control panel allows for precise programming of temperature profiles, including ramp rates, dwell times, and cycling sequences, enabling the replication of complex real-world temperature variations, such as the rapid cooling during a cold front or the heat buildup in a traffic jam.
  • Humidity Control: The humidity control system is equally precise, capable of achieving humidity levels from 10% to 95% RH (Relative Humidity), with an accuracy of ±3% RH. It employs a combination of steam humidifiers and dehumidifiers, along with a carefully designed air circulation system. The chamber is equipped with humidity sensors that continuously monitor the internal humidity, and the control system adjusts the humidification or dehumidification processes accordingly. This allows for the creation of stable and dynamic humidity environments, mimicking the diverse moisture conditions that cars may face, from the dry air of a desert to the humid atmosphere of a rainforest. The system also includes a condensate removal mechanism to prevent any water accumulation within the chamber, safeguarding the tested samples and the chamber's internal components.
  • Other Climate Parameters: In addition to temperature and humidity, the chamber can also simulate other environmental factors such as solar radiation, rainfall, and wind. It is equipped with high-intensity UV lamps to replicate the effects of sunlight, a programmable rainfall simulator to test the water resistance of the vehicle, and a variable-speed fan system to generate wind forces. These additional features provide a more comprehensive and realistic testing environment, ensuring that cars are tested under conditions that closely resemble their actual usage scenarios.
• Advanced Instrumentation and Data Acquisition
  • The chamber is outfitted with a comprehensive suite of sensors and instrumentation. Temperature and humidity sensors are supplemented by pressure sensors to monitor any pressure changes that could affect the test results or the performance of the samples. Light sensors can be incorporated to assess the impact of light exposure in combination with temperature and humidity. Additionally, sensors for measuring vibration, acceleration, and electromagnetic interference can be added to evaluate the vehicle's response to various environmental and operational stimuli. These sensors are connected to a state-of-the-art data acquisition system that records and stores all the relevant data. The data acquisition system offers a high sampling rate, typically ranging from 50 to 500 samples per second, ensuring that even the most rapid changes in climate parameters or vehicle performance are accurately captured. The collected data can be accessed and analyzed in real-time or retrieved later for in-depth studies. The system is also compatible with automotive-specific data analysis software and can generate detailed reports and graphs, facilitating the interpretation and communication of test results.
• Compliance with ISO 16750-4 and Safety Features
  • The Customized Climate Test Chamber is designed and manufactured to meet the specific requirements of the ISO 16750-4 standard. It incorporates multiple safety features to protect both the operators and the tested vehicles. The chamber is equipped with an automatic over-temperature, over-humidity, and over-pressure protection system, which shuts down the chamber or activates emergency cooling, dehumidification, or pressure relief processes if the set limits are exceeded. It also has a power failure recovery function, which allows the chamber to resume the test operation automatically once the power is restored, ensuring the integrity of the test sequence. The interior lighting is designed to be explosion-proof and suitable for use in a humid environment. The chamber is also equipped with a fire suppression system, which can quickly extinguish any potential fires that may occur during the test. Additionally, the control panel includes built-in alarms and indicators, which alert the operator in case of any abnormal conditions or system malfunctions.
