IEC 6008 Rapid Temperature Change Test Chamber Laboratory High Low Temperature Climatic Box
Equipment Overview:
1.1 Product Overview
This test chamber can be used to determine the suitability of electronic products, automotive components, and materials for use and storage under conditions such as high humidity, low humidity, constant humidity and heat, rapid high and low temperature cycling, and humidity and heat conditions that cause condensation on surfaces.
This test chamber utilizes the most rational structure and stable and reliable control method available today, resulting in an attractive appearance, easy operation, safety, and high-precision temperature and humidity control. It is ideal for rapid temperature change testing,constant temperature and humidity testing, and cycling humidity and heat testing.
1.2 Product Advantages and Technical Features
1.2.1. Utilizes a multi-path, environmentally friendly, energy-saving (low-noise) mechanical compression refrigeration system.
All materials, parts, components, and raw materials, whether domestically produced or imported, are environmentally friendly. Based on the characteristics of mechanical compression refrigeration, the equipment utilizes a two-stage, multi-path main and bypass system. Multiple main and bypass paths can be adaptively activated based on different operating conditions. The entire system is automatically controlled by an intelligent control system based on operating conditions, eliminating the traditional method of using a thermostat to control the cooling capacity by offsetting the cooling capacity of the heater. This achieves energy savings, not only consuming only 80% of the energy of similar products. It also reduces the operating load of the refrigeration compressor, minimizes equipment vibration and noise, and improves control accuracy. To further achieve this energy-saving effect, variable frequency technology is employed to adapt the refrigeration compressor's cooling output to the varying temperature change rates required in the laboratory, while also controlling power loss to achieve energy savings. Sound absorption and muffler features are incorporated throughout the structure and at various locations during mechanical operation to reduce overall equipment noise.
1.2.2. Independently developed multi-path, multi-stage throttling system (refrigeration system).
This equipment's refrigeration system features capillary main and bypass circuits designed to adapt to varying system operating conditions. This capillary throttling system automatically adjusts to the operating conditions through an intelligent control system, ensuring adjustable flow rates and achieving uniform temperature field changes with minimal temperature fluctuations.
1.2.3. A broadband pressure-balanced temperature control system is employed, achieving rapid temperature control through a fast-converging PID adaptive algorithm. A forced air duct system, comprised of a temperature-regulating chamber, a static pressure chamber, and centrifugal fans, ensures sufficient heat exchange and evenly distributes air through the top perforated plate to every space in the workroom (experimental area), achieving temperature uniformity. To achieve rapid temperature convergence, our company collaborated with South Korea's Samwon Corporation to develop a dedicated, custom-designed PID adaptive algorithm. This control method continuously adjusts control based on temperature conditions, achieving rapid convergence, minimal temperature overshoot, and high stability.
1.2.4. Remote Visual Control.
The equipment features a human-machine interface and a touch-mode automated control system for automatic control. It also connects to a remote computer for remote monitoring via an RS485 communication interface. The entire system utilizes a graphical interface, enabling simple and rapid control and management. Fault notifications are automatically displayed, providing graphically-guided troubleshooting and solutions, guiding users through quick troubleshooting.
