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

• •Controller: It adopts the controller imported from South Korea Sanwon and the self-developed control system, which can be equipped with Siemens control system and equipped with RS232, RS485 and Ethernet communication ports.
• •Programmable control: It supports setting experimental programs, such as heating, cooling, constant temperature time, etc., and can execute multiple program settings, and supports advance reservation startup function.
• •Multiple languages optional: English, Korean, Russian, Chinese and Japanese.
• •Remote monitoring: Using SAMWON-EZNET network remote technology to achieve remote control, the test chamber can be monitored at any time, and the current data can be viewed through the user's PC and mobile phone, which improves the convenience of testing.

The specific control system of the test chamber will vary depending on the model. Please read the "Sanwood Environmental Test Chamber Manual" carefully before use and comply with the safety operating procedures.

The refrigeration system of the test chamber is a complex and important system. The stability of the refrigeration system is crucial to the accuracy and reliability of the test results.

• •Sanwood Technology has developed a refrigerant hot gas defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant steam into the heat exchanger in 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 an internationally renowned brand. In cooperation with Japan's Saginomiya and the United States' Sporlan, the EPV series and XUP series energy-saving system quick-opening solenoid valves have been developed, with an all-weather service life of more than 15 years. And began to develop a new Danfoss AKV series throttling electronic expansion valve system, which is more efficient and energy-saving, and reduces noise.
• •Optimize the layout of the refrigeration system, and adopt VRF (refrigerant flow control) technology based on the 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 a modular design, with low failure rate, few welding points, high refrigeration efficiency, good reliability, simple maintenance, and low maintenance cost.
