  • The humidity range of 10% to 95% RH, with an accuracy of ±2% RH, allows for a comprehensive evaluation of the effect of moisture on home appliances. High humidity can affect the performance of components such as compressors and condensers, while low humidity can cause drying and cracking of certain materials. The ability to precisely control the humidity level is essential for understanding and mitigating these potential issues.
• Testing Volume and Payload Capacity
  • The chamber offers a spacious testing volume, typically ranging from 10 m³ to 50 m³, depending on the specific model. The payload capacity can handle large home appliances, with a maximum capacity of up to several tons, allowing for the testing of full-sized refrigerators, freezers, and other similar appliances.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 200 Hz, providing a highly detailed record of the temperature and humidity changes. The resolution of the temperature data is 0.1°C, and the humidity data is 0.1% RH. This high-resolution data is invaluable for identifying even the slightest trends and potential failure points, allowing for a more accurate assessment of appliance performance.

4. Product Functions

• Accurate Simulation of Environmental Conditions
  • The primary function of the chamber is to provide a precise and reliable simulation of temperature, humidity, and other environmental conditions. By subjecting home appliances to controlled environmental stresses, it allows manufacturers and researchers to evaluate their performance and durability. This is crucial for ensuring the quality and safety of home appliances, as any degradation or failure during use could lead to food spoilage, energy inefficiency, or even safety hazards.
• Product Design Optimization and Quality Control
  • Through a series of tests on different appliance prototypes, the data obtained from the chamber can be used to optimize product designs. Engineers can analyze the behavior of various materials and components under different temperature and humidity stresses and make modifications to enhance the overall performance and integrity. The chamber also serves as a vital tool for quality control, ensuring that each batch of appliances meets the required environmental resistance standards. For example, in the manufacturing of refrigerators, testing in the chamber can help ensure the proper functioning of the cooling system, the insulation quality, and the durability of the appliance's exterior.
