Walk-in constant temperature and humidity test chamber is an important tool for RD and quality control in many industries, which helps to improve the reliability and market competitiveness of products. Walk-in constant temperature and humidity test chamber is widely used in many fields due to its superior control performance and large-capacity design, mainly including the following aspects:

• •Electronic and electrical industry: Test the reliability and stability of electronic components and equipment in high temperature and high humidity environment. Widely used in life testing and quality control of mobile phones, computers, household appliances, etc.
• •Automotive industry: Evaluate the adaptability of vehicles and their components under extreme climatic conditions. For example, environmental adaptability tests are conducted on automotive electronic equipment, interior materials, etc. to ensure their durability.
• •Aerospace: Test the performance of aerospace equipment under extreme conditions such as high temperature, high humidity, and air pressure changes. Used to test components of satellites, aircraft and spacecraft to ensure their reliability in space environments.
• •Material science: Study the performance changes and durability of materials under different temperature and humidity conditions. Used to test the aging and corrosion behavior of materials such as plastics, rubber, and metals to evaluate their reliability in long-term use.
• •Batteries and energy storage devices: Test the performance and life of batteries under different temperature and humidity conditions, and conduct environmental adaptability tests on lithium batteries and other energy storage devices to verify their reliability in actual use.

When conducting tests in a walk-in constant temperature and humidity test chamber, some international and industry standards are usually required to be followed. These standards ensure the scientificity, accuracy and repeatability of the test. The following are some common test standards:

• •IEC 60068-2-30: This is an International Electrotechnical Commission (IEC) standard that mainly involves the tolerance test of equipment under specific humidity and temperature conditions. It is suitable for reliability testing of electronic products, components and systems.
• •MIL-STD-810: This is a US military standard that contains multiple environmental test methods, including damp heat testing. It is widely used in the environmental adaptability evaluation of military equipment and related industrial products.
• •ISO 9001: Although the quality management system standard is not specifically for temperature and humidity testing, it emphasizes the necessity of quality control to ensure the quality management of products during production and testing.
• •JIS C 60068-2-78: Japanese Industrial Standard for performance testing of equipment and materials in damp and hot environments. It is widely used in reliability assessment of electronic products, automobiles and other fields.

The walk-in temperature humidity test chamber also complies with IEC 60068, ASTM D 2247, BS EN 61300-2-48, JIS Z 0202 and other test standards

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. 
• •Protection system: protects the safety of machines and users through overheating and overcurrent cut-off mechanisms.
• •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.

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.
