Equipment technology advantages
1. It adopts a 7 "TFT true color LCD touch screen (as shown in the bottom right picture), which is larger, more intuitive, easy to operate, stable in operation, and more energy-efficient than other screens.
2. The evaporator adopts a water immersion leak detection method to check for leaks and ensure stable operation of the equipment.
3. Adopting modular refrigeration units can ensure manufacturing quality, and maintenance and replacement are very convenient.
4. Adopting a high uniformity positive pressure air duct system, the temperature is uniformly high.
5. Adopting new automatic defrosting technology to shorten defrosting time and greatly increase the efficiency of equipment use.
6. It has multiple safety protection measures, fault alarm display, and display of fault causes and troubleshooting methods.
Shell: Made of high-quality cold-rolled steel plate with electrostatic spraying, it has good appearance and protective performance.
Inner box: usually made of stainless steel plate, with the characteristics of corrosion resistance and easy cleaning.
Insulation layer: High density glass fiber cotton is used to ensure good insulation effect and reduce heat loss.
Observation window: equipped with multi-layer insulated tempered glass observation window, convenient for observing the internal situation of the test chamber.
Door: Adopting double-layer sealed doors to ensure good sealing performance and prevent temperature leakage.
Control panel: located on the front of the test chamber, convenient for operation and setting test parameters.
Different temperature range impact: correspondingly cut off by the multi-stage evaporator structure, control the evaporation area to match the refrigeration expansion valve, use the refrigeration system output to reasonably reduce the output of the heater neutralization, and achieve constant energy saving; There is also an independent ventilation valve that operates to introduce ambient air during exhaust (room temperature recovery).
The air intake draws in outside air when exposed to ambient temperature.
The exhaust port is designed to discharge hot air from the mechanical room and testing area at a predetermined time.
Set the start time of the experiment in advance, and the test box will automatically start and prepare to start the experiment.
Exposure time shortening function.
After the downwind temperature of the experimental area reaches the exposure temperature, it switches to the next exposure function.
Pre processing/post-processing functions.
Before or after the cyclic test, the sample is exposed to a high temperature environment (heat treatment) for a certain period of time.
Dry operation function.
Operate the test piece for a certain period of time.
Main Features
1. Control: The equipment adopts a self-developed control system, combined with the latest fuzzy computing technology, which can automatically analyze the load capacity and adjust the refrigerant flow rate reasonably, making the equipment operate more accurately, stably, and easily.
2. Efficient and energy-saving: Through advanced control systems and refrigeration technology, the equipment achieves up to 20% energy-saving effect while ensuring testing accuracy.
3. Safety protection: The equipment has multiple safety protection measures, such as fault alarm display, fault cause and troubleshooting method display, etc., to ensure the safety and reliability of the testing process.
4. Modular design: By using modular refrigeration units, not only is the manufacturing quality guaranteed, but maintenance and replacement are also very convenient.
5. High uniformity air duct system: A positive pressure high uniformity air duct system is used to ensure high temperature uniformity inside the box and provide a stable testing environment for the sample.
6. Automatic defrosting technology: The equipment adopts the latest automatic defrosting technology, greatly reducing defrosting time and improving equipment efficiency.

The power supply section automatically controls the power supply to compressors, fans, electric heaters, humidifiers, etc. through contactors. It is further divided into temperature, control, and fault protection sections: temperature and control are achieved by comparing the temperature of the return air with the user set temperature and humidity through a temperature and controller, automatically running the compressor (cooling, dehumidification), humidifier, electric heating (heating), and other components to achieve automatic control of constant temperature and humidity.
Experimental standards:
Meet GB/T2423.22 (IEC60068-2-14); ISO16750; Temperature shock test in series standards such as IPC-TM-650.
Refrigeration system
Refrigeration system and compressor: In order to ensure the cooling rate and minimum temperature requirements of the test chamber, this test chamber adopts a binary cascade air-cooled refrigeration system composed of an imported compressor. The compressor adopts the fully enclosed "Taikang" brand compressor imported from France or the semi enclosed "Bizelle" brand compressor imported from Germany.
Cooling system: air-cooled or water-cooled cooling system.
