Walk-in Environmental Test Chamber

The walk-in environmental test chamber is a test device that can simulate various environmental conditions,it is used to evaluate the performance of products or materials in different environments.

• •Design features : It has a large internal space, and personnel can directly enter the box to operate or observe .
• •Temperature and humidity control technology : Equipped with advanced temperature and humidity control system, it can accurately simulate various extreme environments through precise sensors and intelligent controllers to help test the performance and reliability of samples.
• •Monitoring and alarm system : Equipped with a multi-point temperature and humidity monitoring system, it can trigger an alarm when the temperature or humidity exceeds the preset range to avoid equipment damage or test data distortion .
• •Convenience of operation and maintenance : The operation interface is simple and usually equipped with a smart touch screen, remote monitoring system and automatic control program

Walk-in test chambers are widely used in several industries such as aerospace and defense , automotive industry , large-scale electronics and telecommunications due to their versatility and wide range of testing capabilities .

• •Aerospace and Defense:It can effectively simulate extreme environmental conditions such as high pressure, high temperature, and high humidity, conduct rigorous reliability tests on spacecraft, satellites, and avionics equipment, and provide strong support for aircraft performance verification.
• •Automotive Industry:Walk-in test chambers are used to test the performance of automotive parts and complete vehicles under extreme temperature and humidity conditions, such as the temperature resistance, moisture resistance and long-term stability of components such as batteries, electronic control units, lamps, and vehicle systems .
• •Electronics and Telecommunications:Walk-in test chambers help evaluate the reliability and functionality of electronic equipment, telecommunications equipment, and electrical components by subjecting them to controlled temperature, humidity, and other conditions.

In addition, walk-in environmental testing rooms are also used in fields such as materials science, food science, and biomedicine to evaluate the performance changes of materials, foods, biological samples, etc. under different temperature and humidity environments.

A walk-in test chamber is a device used to simulate different environmental conditions for testing. Its test standards usually involve the following aspects:

• •EN 60068-2-2, IEC 60068-2-1, etc., specify the test methods and standards for walk-in test chambers at different temperatures.
• •EN 60068-2-30, IEC 60068-2-30, etc., specify the test methods and standards for walk-in test chambers at different humidity levels.
• •IEC 60068-2-78, GB/T 2423.22, etc., specify the test methods and standards for walk-in test chambers under different pressures.
• •IEC 60068-2-6, GB/T 2423.8, etc., specify the test methods and standards for walk-in test chambers under different vibration conditions.
• •IEC 60068-2 series, GB/T 10589, etc., specify the test methods and standards for the adaptability of walk-in test chambers under different environmental conditions.

At the same time, manufacturers of walk-in test chambers will also design and produce equipment according to relevant standards and technical specifications to ensure the accuracy and reliability of test results.

The controller system of Sanwood test chamber adopts world leading hardware and software systems to ensure that the test box operates under preset conditions, providing accurate and reliable experimental data to help users achieve precise control and data collection of various experimental conditions.

• •Controller: The TEMI 1500 controller imported from Sanwontech in South Korea and the self-developed Siemens control system are used, equipped with RS232, RS485, and Ethernet communication ports. 
• •Programmable control: supports setting experimental programs, such as heating, cooling, holding time, etc., and executing multiple program settings.Support advance reservation for power on function.
• •Multiple languages optional: English, Korean, Russian, Chinese, and Japanese.
• •Precise control: able to accurately set and maintain specific temperature ranges and humidity levels, accurately simulate various environments.
• •Remote monitoring: Using SAMWON-EZNET network remote technology to achieve remote control, the test chamber can be monitored at any time and emails can be sent to users' PCs and phones, enhancing convenience.

The specific control system of the test chamber may vary depending on the model, so it is necessary to carefully read the Sanwood Environmental Test Chamber Manual and follow safety operating procedures before use.

The refrigeration system of the test chamber is a complex and important system, and the quality of the refrigeration system is crucial for the accuracy and reliability of the test results.

• •Sanwood has developed hot air refrigerant defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant vapor into the heat exchanger inside the test chamber. This not only ensures that the evaporator does not frost, but also greatly reduces the energy consumption of the equipment.
• •The refrigeration unit adopts international famous brands and cooperates with Japan's Eginomiya and the US Sporan to develop EPV series and XUP series quick opening solenoid valves for energy-saving systems, with an all-weather service life of over 15 years. And began to develop the new Danfoss AKV series throttling electronic expansion valve system, which is more efficient and energy-saving.
• •Optimizing the layout of the refrigeration system adopts VRF (refrigerant flow control) technology based on PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.
• •The refrigeration system adopts modular design, achieving low failure rate,less welding joints, high refrigeration efficiency, good reliability, simple maintenance, and low repair costs.
