The application of temperature humidity test chambers in these fields not only improves the quality and reliability of products, but also promotes the development of scientific research and technological innovation.

The Test Standards Of The test Chamber

The temperature humidity test chamber can accurately control temperature and humidity and provide stable environmental conditions. At the same time, it can also simulate some extreme environments, such as high temperature, low temperature, high humidity and low humidity, to test the durability and reliability of the product. The following are some common standards and specifications for desktop constant temperature and humidity test chambers:

• IEC 60068-2-1 “Environmental testing Part 2: Test methods Test A: Low temperature”: specifies the methods and requirements for low temperature tests.

• 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 environmental testing methods, including high temperature and high humidity testing.

The temperature humidity test chambers also comply with test standards such as JIS Z 0202, ANSI/TIA/EIA 455-162, MIL-STD-810, ASTM D 2247, BS EN 61300-2-48, etc.

Control System Of The Test Chambers

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, 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.

Refrigeration System Of The Test Chamber

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.
