Overview
HZAOC GDJS-100C 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.
Features
1. The box adopts the overall structure, the inner side is stainless steel plate, the outer side is sprayed 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 to ensure sealing.
3. The observation window is a multi-layer conductive film tempered hollow Glass, built-in anti-frost heating wire and lighting.
4. Equipped with test holes with silicone rubber plugs for both thermal insulation performance.
5. Adopt the upper air supply and lower return air mode, and the temperature sensor is placed in a trend.
6. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor and uses R404A environmentally friendly refrigerant.
7. The refrigeration system is equipped with multiple safety protections such as high voltage control, overvoltage and overload.
8. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life.
9. Adopt steam boiler electric heating and humidification method, with water level control and anti-dry burning device.
10. High Accuracy Digital Temperature and Humidity Controller for accurate and stable control.
11. The control system is equipped with multiple safety protection and interlocking devices such as phase loss, phase sequence error, over-temperature power failure, and leakage.
12. Equipped with an independent over-temperature protector, it can still reliably protect the equipment when the main controller malfunctions.
Principle
The equipment adjusts the environment in the working room through components such as evaporator, electric heater, humidifier and fan in the air conditioning cabinet. The refrigeration system uses a cascade refrigeration cycle to achieve rapid cooling through components such as Compressor, condenser and evaporator. The heating and humidification systems generate heat and steam through electric heaters and electric heating and humidification boilers respectively. Sensor signals are collected by High Accuracy temperature and humidity controllers, and PID adjustment is carried out through actuators such as solid state relays, so as to achieve accurate control of temperature and humidity and alternating cycle.
