Double layer constant temperature and humidity test chamber vertically stacked, dual chamber independent temperature control, energy-saving and high-efficiency environmental testing equipment

Description :

  A double-layer constant temperature and humidity chamber is an environmental simulation testing device designed with vertically stacked dual independent chambers, specifically designed for scenarios that require simultaneous testing under different or identical conditions. The device achieves independent setting and synchronous operation of temperature and humidity parameters through two physically isolated independent chambers, effectively solving the pain points of low testing efficiency and large footprint of traditional single cabin equipment. Typical operating conditions include aging testing of electronic components, environmental adaptability verification of materials, and weather resistance testing of small components. As a representative of the multi-layer constant temperature and humidity test chamber, it not only meets the testing requirements of international and domestic standards such as GB/T 2423 and IEC, but also significantly improves the space utilization and energy efficiency of the laboratory through the design concept of "one on top of two", making it an ideal choice for modern quality testing laboratories.

  In terms of specifications and processes, double-layer constant temperature and humidity chambers usually use high-quality stainless steel inner tanks and cold-rolled steel plate spray coated shells to ensure the corrosion resistance and aesthetics of the equipment. The core refrigeration system often uses imported compressors combined with environmentally friendly refrigerants, while the heating system uses nickel chromium alloy electric heaters. The common humidification methods are ultrasonic humidification or steam humidification to ensure the accuracy and stability of temperature and humidity control. The typical temperature range covers -70 ℃ to+150 ℃, and the humidity range is controlled between 20% RH and 98% RH. The fluctuation is usually better than ± 0.5 ℃ and ± 2% RH. The equipment complies with environmental testing standards for electrical and electronic products such as GB/T 2423.1/2/3/4, and has complete over temperature, over pressure, and overload protection functions to ensure the safety of long-term operation. The dual cabin independent control system allows users to program the upper and lower chambers separately, meeting diverse testing needs.

  When selecting, special attention should be paid to the chamber size and load capacity of the double-layer constant temperature and humidity chamber to ensure that the test sample can be placed reasonably and does not affect the air duct circulation. This device is suitable for research institutions, quality inspection agencies, and enterprise laboratories in industries such as electronics, automotive, and plastics. Compared with large walk-in laboratories, dual compartment independent temperature and humidity test chambers save more space; Compared to two standalone machines, it reduces the power interface requirements and overall footprint, and lowers installation complexity. Not applicable scenarios include testing of ultra large volume samples or testing of high-precision instruments sensitive to vibration (unless the equipment is specifically equipped with anti vibration structures). If extreme rapid temperature change testing is required, it should be confirmed whether the equipment is equipped with linear heating and cooling function. Ordinary models may not be able to meet the extreme temperature change rate requirements. Specific testing standards and parameter indicators need to be clarified before procurement.

  When installing a double-layer constant temperature and humidity box, it is necessary to ensure that there is sufficient heat dissipation space around the equipment. It is usually recommended to reserve a distance of more than 60cm on the back and sides, and a space of more than 100cm on the top to ensure the heat dissipation effect of the refrigeration system. In daily maintenance, it is recommended to regularly clean the condenser dust, check the water level and quality of the water tank, and use deionized water or distilled water to prevent humidifier scaling and blockage. Sensor calibration is required every six months to ensure the accuracy of thermal and humidity data. Common malfunctions such as abnormal humidity display are often caused by the hardening or dehydration of wet ball gauze. Timely replacement of gauze can solve the problem. If the compressor has a high pressure alarm, it is necessary to check whether the ambient temperature is too high or whether the condensing fan is working properly. Standardized operation and maintenance can extend the service life of the multi-layer constant temperature and humidity test chamber, ensuring continuous and stable test data output.
