Temperature Humidity Control Walk In Chamber For Home

1. Product Name and Purpose

2. Product Features

• Spacious and Sturdy Construction
  • The walk-in chamber is constructed with a heavy-duty framework, typically made of corrosion-resistant stainless steel or high-strength alloy. This ensures its durability and stability, allowing for the accommodation of large and bulky home appliances. The interior is designed to provide a controlled and isolated environment. It is lined with a non-reactive and heat-insulating material to prevent any interference with the testing process. The door is engineered with a reliable sealing mechanism, incorporating a high-quality gasket and a multi-point locking system, ensuring an airtight enclosure. The chamber also features a large viewing window made of toughened glass, allowing for visual inspection of the testing process without compromising the integrity of the test environment.
• Precision Environmental Control Systems
  • Temperature Control: Capable of maintaining a wide temperature range, from -30°C to +60°C, with an accuracy of ±0.5°C. It utilizes advanced refrigeration and heating technologies, such as industrial-grade compressors and high-capacity heating elements. The control system incorporates a feedback loop, with multiple temperature sensors strategically placed throughout the chamber, ensuring uniform temperature distribution. The user-friendly control panel allows for precise programming of temperature profiles, including rapid temperature changes and extended soak times, replicating real-world conditions like the cold environment of a freezer compartment or the heat generated during the operation of a dryer.
  • Humidity Control: The humidity control system can achieve humidity levels from 10% to 95% RH (Relative Humidity), with an accuracy of ±3% RH. It employs a combination of steam injection and dehumidification techniques, along with a carefully designed air circulation system. Humidity sensors continuously monitor the internal environment, and the control system adjusts accordingly to create the desired humidity levels. This is essential for testing the effects of moisture on appliances, such as the rusting of metal parts in a humid bathroom or the performance of electronic components in a humid climate.
  • Dust and Particulate Simulation: To assess the impact of dusty environments on home appliances, the chamber is equipped with a dust injection system. It can introduce controlled amounts of various types of dust, such as silica dust or household dust, into the testing environment. This allows for the study of how appliances like air purifiers, vacuum cleaners, and the cooling fans of electronic devices handle the ingress of such contaminants. The system also includes a filtration mechanism to prevent the dust from escaping and contaminating the surrounding area.
  • Chemical Exposure Testing: The chamber can also simulate chemical exposures that appliances may face in a household setting. It can introduce common household chemicals, such as detergents, cleaning agents, and even food and beverage spills, in a controlled manner. This enables the evaluation of how appliance surfaces, seals, and internal components resist corrosion and degradation caused by these chemicals. The chamber is designed with proper ventilation and drainage systems to manage the chemical residues and fumes.
• Advanced Instrumentation and Data Acquisition
  • The chamber is outfitted with a comprehensive suite of sensors and instrumentation. In addition to temperature and humidity sensors, it includes sensors for measuring power consumption, vibration, and noise levels of the tested appliances. 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 environmental conditions or appliance 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 appliance industry-specific data analysis software, enabling the generation of detailed reports and graphical representations of the test results.
• Safety and Compliance Features
  • The Customized Walk-In Environmental Chamber is designed with multiple safety features. It has an automatic shutdown system in case of any critical malfunction, such as overheating, over-humidity, or excessive power consumption. The chamber is also equipped with a fire suppression system, which can quickly extinguish any potential fires that may occur due to electrical faults or chemical reactions. The ventilation system is designed to remove any harmful gases or fumes generated during testing, protecting the operators and the surrounding environment. Additionally, the chamber complies with relevant appliance testing standards and regulations, ensuring that the testing procedures are reliable and recognized within the industry.

3. Specific Parameters

• Chamber Size and Capacity: The walk-in chamber is available in various sizes, with interior volumes ranging from a few cubic meters to larger configurations suitable for testing multiple large appliances simultaneously. For example, a smaller chamber might have an interior volume of 5 cubic meters, while a larger one could be 20 cubic meters or more. The interior dimensions are optimized for proper air circulation and uniform environmental parameter distribution, ensuring that all parts of the tested appliances are effectively exposed to the simulated conditions.
• Temperature Cycling Rate: Can perform temperature cycles at a rate of 2 to 4 cycles per day, depending on the specific test requirements. For example, it can rapidly cool from +40°C to -10°C in a matter of minutes and then heat back up, subjecting the appliances to significant thermal stress, which is essential for evaluating thermal fatigue resistance.
• Humidity Cycling Rate: The humidity can be cycled within 20 to 40 minutes, allowing for the simulation of rapid changes in moisture conditions, such as transitioning from a dry living room to a humid kitchen environment.
• Dust Concentration and Exposure Time: The dust injection system can introduce dust concentrations ranging from 10 milligrams per cubic meter to 1000 milligrams per cubic meter, and the exposure time can be set from a few hours to several days, depending on the desired test severity.
• Chemical Concentration and Application Method: The chamber can introduce chemical concentrations ranging from 1% to 10% (by volume) of common household chemicals, and the application method can be adjusted to mimic spills, sprays, or long-term exposures.
• Data Acquisition Rate: The data acquisition system samples sensor data at a rate of 200 samples per second, ensuring that even the most minute and rapid changes in temperature, humidity, power consumption, vibration, or other parameters during the test are accurately recorded and can be analyzed in detail. This high sampling rate provides valuable insights into the performance and potential failure modes of the home appliances.
• Compliance with Appliance Standards: Complies with a range of appliance industry standards, such as IEC 60335 for safety and performance testing of household and similar electrical appliances. This ensures that the testing is conducted in a consistent and recognized manner, facilitating market access and compliance with regulatory requirements for home appliances.
