Three-layer Temperature Humidity Test Chamber

Three-layer temperature and humidity test chamber adopts three sets of independent refrigerant system, heating humidifying system and control system, which greatly reduces the operating cost, it is the mandatory test equipment for aviation, automobile, home appliance, scientific research and other fields.

• •With rogrammable control function, which can set fixed value/program, can set different temperature and humidity change curves and test time.
• •Can customized the chamber’s volume, temperature and appearance on demand.
• •The volume, temperature and appearance of the test chamber can be customized.
• •Optional more environmentally friendly, efficient and safe CO2 refrigeration system (GWP=1, ODP=0).
• •Designed and manufactured in accordance with international standards, with performance of higher reliability and better stability.
• •Local installation and commissioning team can be arranged for commissioning and installation.

Three-layer temperature humidity test chamber is widely used in electronics, electrical appliances, cell phones, telecommunications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other fields. For example:

• •Scientific research institutions: for basic research, technology development and product testing, especially in climate simulation and environmental adaptation research.
• •Food industry: used to test the shelf life and quality change of food packaging materials, finished products and raw materials under different environmental conditions.
• •Electronic Semiconductor Industry: used to test the performance and stability of electronic components and devices, such as chips, cell phones, computers and other consumer electronics, under different temperature and humidity conditions.
• •Materials science: for evaluating the physical and chemical properties of materials in high humidity and high temperature environments, especially polymers, coatings, composites and etc.

Three-layer temperature humidity test chamber through the simulation of different temperature and humidity environment, it can help enterprises and research institutions to carry out product reliability assessment, improve product quality and reliability performance.

The test standard of three-layer temperature humidity test chamber usually varies according to the industry and products, the following are some common standards and regulations:

• •IEC 60068-2-78: "Environmental tests Part 2-78: Tests Test Cab: Constant humidity and heat test": Detailed the specification for the constant humidity and heat test.
• •ISO 16750: International Organization for Standardization (ISO) standard for automotive electronic equipment, which includes test requirements for environmental conditions.
• •MIL-STD-810: A military standard developed by the U.S. Department of Defense that covers a variety of methods for environmental testing, including high temperature and high humidity testing.
• •JIS Z 0202: Japanese Industrial Standard concerned with testing the resistance of materials and equipment under environmentally simulated conditions.

The three-layer temperature humidity test chamber also complies with IEC 60068,MIL-STD-810, 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 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.
