TVs / Refrigerators / Air Conditioners Constant Climate Chamber Stainless Steel

1. Product Name and Purpose

2. Product Features

Precise Climatic Control

• Wide Temperature Range
  • The chamber is capable of maintaining a broad temperature range suitable for testing these appliances. It can reach extremely low temperatures, typically as low as - 70°C, which is useful for testing refrigerators' ability to maintain proper cooling in cold storage environments or air conditioners' performance in sub - zero temperatures. On the other hand, it can achieve high temperatures of up to + 150°C, simulating the heat in a poorly ventilated room during a hot summer or the conditions in a sun - exposed area.
  • The temperature control is highly precise, with an accuracy of typically ±0.5°C. This precision is crucial as even small temperature variations can significantly affect the performance of these appliances. For example, a slight deviation in temperature can impact a TV's display quality, a refrigerator's cooling efficiency, or an air conditioner's energy consumption.
• Accurate Humidity Regulation
  • Humidity levels within the chamber can be precisely regulated from as low as 10% relative humidity to as high as 95% relative humidity. High humidity can cause condensation problems in TVs, rusting in refrigerators, and reduced efficiency in air conditioners. Low humidity, on the other hand, can lead to static electricity issues in TVs and affect the moisture - sensitive components of refrigerators and air conditioners.
  • The humidity control accuracy is usually within ±3% relative humidity. This ensures that the test environment closely replicates the real - world humidity conditions that these appliances may encounter, providing reliable and consistent test results.

Spacious and Adaptable Test Volume

• Large Test Volume
  • Given the size of TVs, refrigerators, and air conditioners, the constant climatic test chamber features a large test volume. It typically ranges from 10 m³ to 50 m³, allowing for the easy accommodation of these large - sized appliances. The spacious interior ensures that the entire appliance can be exposed to the uniform climatic conditions without any spatial constraints.
• Adjustable Interior Configuration
  • The chamber's interior is designed with an adjustable configuration to accommodate different types and sizes of appliances. It may include movable shelves, brackets, and fixtures that can be adjusted to securely hold and position the TVs, refrigerators, or air conditioners during the test. This adaptability ensures that the appliances are properly placed and exposed to the desired climatic conditions for accurate testing.

Stable and Uniform Environment

• Uniform Climatic Distribution
  • The interior of the constant climatic test chamber is designed to provide a uniform distribution of temperature and humidity throughout the test volume. Advanced air circulation systems and multiple sensors are strategically placed to ensure that the temperature variation within the chamber is typically within ±1°C, and the humidity variation is within ±5% relative humidity.
  • For large appliances like TVs, refrigerators, and air conditioners, a uniform environment is essential. It ensures that all parts of the appliance are exposed to the same climatic conditions, eliminating any biases in the test results and providing a more accurate representation of the appliance's performance under real - world conditions.
• Long - Term Stability
  • The chamber is capable of maintaining stable climatic conditions over long periods of time. This is crucial for conducting endurance tests on these appliances, which may require continuous operation under specific temperature and humidity conditions for days, weeks, or even months. The chamber's stability ensures that the test conditions remain constant throughout the test, providing consistent and comparable results.

Multiple Test Modes and Customization

• Programmable Test Profiles
  • Operators have the flexibility to create programmable test profiles that simulate the complex and variable environmental conditions that these appliances encounter in real life. These profiles can include cyclic changes in temperature and humidity to mimic seasonal variations, sudden changes to simulate extreme weather events, or custom - tailored profiles based on specific product requirements. For example, a test profile can be designed to simulate the temperature and humidity changes that an air conditioner may experience during a day in a tropical climate, with high humidity in the morning, increasing temperature during the day, and a sudden drop in temperature and humidity in the evening.
  • The ability to create customized test profiles allows manufacturers to test their appliances under specific conditions that are relevant to their intended use. This provides more accurate and meaningful test results, enabling them to better understand how their products will perform in different real - world scenarios.
• Optional Test Accessories
  • The constant climatic test chamber can be equipped with a variety of optional test accessories to meet specific testing requirements. For TVs, lighting systems can be added to simulate different lighting conditions, such as bright sunlight or dim indoor lighting. For refrigerators, temperature and humidity sensors can be placed inside the unit to monitor the internal environment during the test. For air conditioners, external fans can be used to simulate different air flow conditions, and power meters can be installed to measure the appliance's energy consumption.

User - Friendly Operation and Monitoring

• Intuitive Control Interface
  • The chamber is equipped with an intuitive control interface that simplifies the operation process. The interface allows operators to easily set and adjust test parameters, such as temperature, humidity, test duration, and test profiles. It also provides a clear display of the current test status, including the actual temperature and humidity values, elapsed test time, and any error messages.
  • The user - friendly design ensures that even operators with limited technical expertise can efficiently conduct tests on TVs, refrigerators, and air conditioners.
• Remote Monitoring and Control
  • Many models of the constant climatic test chamber offer remote monitoring and control capabilities. This feature is highly beneficial for manufacturers and quality control teams, as it allows them to monitor the test progress and adjust the test parameters from a remote location, such as an office or a control center. This is especially useful for long - term tests or when multiple tests are being conducted simultaneously.
  • Remote monitoring and control enable timely intervention in case of any issues, ensuring the smooth and efficient operation of the testing process.

6. Application Areas and Success Stories

• TV Testing
  • A leading TV manufacturer was developing a new series of high - end smart TVs. The TVs were tested in the constant climatic test chamber to evaluate their performance under different environmental conditions. The testing revealed that the TVs' display had issues with color accuracy and contrast at high humidity levels. Based on this result, the manufacturer improved the display's anti - humidity coating and optimized the color calibration algorithms, resulting in better - performing TVs that could maintain excellent picture quality even in humid environments.
• Refrigerator Testing
  • A refrigerator manufacturer was conducting endurance tests on a new model. The refrigerators were placed in the constant climatic test chamber and subjected to cyclic temperature and humidity changes to simulate real - world usage over several years. The testing showed that the gasket around the refrigerator door was prone to wear and tear at low temperatures, leading to air leakage and increased energy consumption. The manufacturer then improved the gasket material and design, enhancing the refrigerator's energy efficiency and durability.
• Air Conditioner Testing
  • An air conditioner company was developing a new energy - efficient model. The air conditioners were tested in the constant climatic test chamber to measure their cooling and heating capacity, energy consumption, and noise levels under different ambient temperature and humidity conditions.
