HZAOC GDJS-150B High and Low Temperature Alternating Damping heat testing chamber is suitable for investigating the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, as well as the adaptability test of storage, transportation and use in high and low temperature environments.
1. The box adopts the overall structure, the inner side is stainless steel plate, the outer side is sprayed Cold rolled steel plate, and the thermal insulation material is ultra-fine Glass thermal insulation cotton. 2. The door is made of double-decked silicone rubber sealing material, and the observation window is made of multi-layer conductive film tempered hollow Glass and is equipped with frost-proof heating wire and lighting. 3. Equipped with test holes with silicone rubber plugs for both thermal insulation performance. 4. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor and uses R404A environmentally friendly refrigerant. 5. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life. 6. The humidification system adopts the steam boiler electric heating humidification method, and is equipped with water level control and dry burning prevention devices. 7. The control system adopts High Accuracy Digital Temperature and Humidity Controller, which does not drift for long-term operation. 8. The control system is equipped with comprehensive safety protection measures, including phase loss, over-temperature, leakage, etc., and is equipped with an independent over-temperature protector. 9. The electrical control system is equipped with an interlock device to ensure that the heating and humidification system cannot be started when the fan is not started or overloaded.
The test chamber adjusts the temperature and humidity in the working room through equipment such as evaporators, electric heaters, humidifiers and fans in the air-conditioning cabinet. The refrigeration system adopts a cascade refrigeration cycle, and the low-temperature grade refrigerant evaporates in the evaporative condenser to absorb the heat of the high-temperature grade refrigerant, thus achieving a low-temperature environment. Heating and humidification are performed by electric heaters and steam boilers controlled by PID respectively. The temperature sensor is placed in a trend monitoring environment, and the control system precisely adjusts according to the set parameters to realize the circulation of upper air supply and lower air return.
Test on moisture resistance and high and low temperature adaptability of electrical and electronic products, components, parts and materials
Connect 380V +/- 10% power supply. 2. Set the required Temperature range (-30~ 150 ℃), Humidity range (30~ 98% RH) and timing time (0~ 999h) through the buttons on the operation panel. 3. Start the equipment and the circulating fan starts to work. 4. The equipment automatically runs the refrigeration, heating or humidification program according to the settings to achieve alternating temperature and humidity. 5. During the test, the inside of the box can be illuminated through the observation window, and test holes can be used if necessary. 6. After the test is completed, the equipment stops running according to the program and the sample is removed.
The device needs to be used under 380V +/- 10% power supply conditions. Make sure the circulating fan is running normally before starting, otherwise the heating and humidification system will fail to start. Pay attention to the water level control device to prevent the humidifier from dry burning. Do not open the door frequently during the operation of the equipment to avoid affecting the stability of temperature and humidity. Regularly check whether the refrigeration system pressure and safety protection devices are effective. When the fault indicator light is on, it should be troubleshooted before continuing to use it. Please disconnect the power supply during maintenance and operate it by a professional.
