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 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 are available: 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.
