6. The core of the refrigeration system adopts the French Taikang fully enclosed Compressor, and the high-efficiency slope evaporator and SWEP plate cold and heat exchanger are used.
7. With a complete safety protection system, covering Compressor, humidification system, test chamber and power supply and other aspects of fault alarm and protection functions.
8. The observation window is internally illuminated with LED and can be heated to prevent fogging.
9. Adopt nitrogen flushing welding, oxygen-free copper pipe, bending machine and other precision installation processes to ensure system reliability and life.
Principle
The equipment creates the required temperature and humidity environment in a closed working room through a mechanical compression refrigeration system (single stage or cascade) and a heating system, combined with humidification and dehumidification devices. The control system collects the environment parameters in the box in real time through the A-class PT100 armored Thermocouple (temperature) and dry wet-bulb temperature meter (humidity) method, and uses the equilibrate Conditioning control algorithm (BTC/BTHC) to coordinate the actions of the refrigeration, heating, humidification, dehumidification and other executive components, quickly and accurately achieve and maintain the set temperature and humidity conditions, and realize the environment simulation of fixed value or Linear dispersion changes according to the preset program.
Applications
Electronic product reliability testing, automotive parts environmental testing, material research, aerospace parts testing, military products environmental adaptability assessment, chemical product stability testing, biological product storage conditions simulation
Standards
GB/T5170.2-2008、GB/2423.1-2008、GB/2423.2-2008、GB/T5170.5-2008、GJB150.3、GJB150.4、GB2423.3-93、GB2423.4-93
Steps
Connect the device to a 380V power supply and ensure that the water supply is normal (if a humidity test is performed).
2. Set the temperature, humidity, time and other parameters required for the test through the 7-inch Touchscreen or connect to the host computer software, or select the preset program.
3. Put the sample to be tested into the studio and close the box door.
4. Start the equipment and run the test.
5. During the test, the data and Linear dispersion can be monitored in real time through the screen, software or data interface (USB, Ethernet, etc.).
6. After the test is completed, the equipment stops running according to the setting and the sample is taken out.
7. Historical data can be exported via USB interface, or remote data management can be performed via Ethernet.
Notice
The equipment should be installed in a well-ventilated place without direct sunlight and away from heat sources.
• Power frequency is stable at 380V and has sufficient capacity (50A).
Before conducting the humidity test, check the quality of the humidified water and the water supply system to avoid water shortage or abnormal water supply.
When placing the sample, the air duct in the working room should not be blocked, and the total load (calorific value) should not exceed the standard load (200W).
• When the equipment is running, do not open the box door frequently, so as not to affect the stability of temperature and humidity and the life of the equipment.
• Regularly check whether the refrigeration system, filtrating device and safety protection function are normal.
Equipment is equipped with multiple protections such as leakage, short circuit, and over-temperature, but operators still need to abide by electrical safety regulations.
• If not used for a long time, the humidification water should be emptied, and the equipment should be cleaned and regularly powered on for maintenance.
