Temperature and humidity cycling in high and low temperature test chambersEquipment composition and working principle

The high and low temperature wet heat test chamber is mainly composed of the following systems:

1. Heating system: It usually adopts electric heating method, which converts electrical energy into thermal energy through electric heating tubes to increase the temperature inside the box. The temperature sensor monitors the temperature inside the box in real time and feeds back the data to the control system. When the temperature is below the set value, the heating system will start to raise the temperature to the desired range.

2. Refrigeration system: used to reduce the temperature inside the box, usually using compressor refrigeration technology to achieve cooling effect through refrigerant circulation.

3. Humidification system: introduce water vapor into the box through spray or humidifier to simulate high humidity environment.

4. Dehumidification system: used to remove excess moisture inside the box to simulate a dry environment.

5. Air circulation system: The air is evenly distributed through fans or blowers to ensure the uniformity of temperature and humidity inside the box.

6. Control system: including temperature controller, humidity controller, PLC controller, etc., used to accurately control the temperature and humidity inside the box and record experimental data.

7. Box structure: usually made of stainless steel or high-quality steel plate, with insulation layer inside to maintain temperature stability inside the box.
