Working Principle of Temperature and Humidity Chamber
Temperature Control
Heating System: The chamber has electric heaters or other elements. They raise the internal temperature. A thermostat or a digital controller controls the heating system. It adjusts the power of the heaters to keep the temperature you want.
Cooling is typically achieved using a refrigeration system. The system includes a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle removes heat from the chamber. The compressor and expansion valve control the temperature.
Temperature sensors track the chamber’s internal temperature. They can be either thermocouples or resistance temperature detectors (RTDs). The sensors provide feedback to the control system. They keep the set temperature accurate.
Humidity Control
Humidification System: Humidity is added to the chamber using a humidification system. This system may involve ultrasonic humidifiers, steam generators, or atomizers. These systems introduce water vapor into the air inside the chamber.
The chamber uses a dehumidification system to reduce humidity. The system is often part of the refrigeration system. The evaporator coil of the fridge cools the air below its dew point. This process condenses moisture and removes it from the air.
Humidity Sensors: Hygrometers or capacitive sensors measure the chamber’s humidity. The sensors provide feedback to the control system. We use this feedback to adjust the humidification and dehumidification processes. They’re adjusted to keep the humidity at the desired level.
Air Circulation
Fans and blowers help keep the chamber’s air at a uniform temperature and humidity. They do this by circulating the air continuously. This helps maintain consistent environmental conditions throughout the chamber space.
Control System
The chamber has a programmable controller. It is a PLC or a microprocessor-based controller. It lets users set and adjust the desired temperature and humidity levels. The controller processes inputs from temperature and humidity sensors. It makes precise adjustments to heating, cooling, humidification, and dehumidification systems.
A user interface is a digital display with buttons or a touchscreen. It lets users input setpoints. They can also create test profiles and track real-time conditions inside the chamber.

Calibration Report: Make a report on the calibration process. Include the instruments used, readings taken, and any adjustments made.
1.Clean the heat sink (condenser) of the cooling unit often. Dusty condensers cause false alarms from high-voltage switch trips. Maintain the condenser monthly. Vacuum the dust from the heat sink. Brush it with a stiff brush or blow it with a high-pressure air nozzle after the machine is turned on.
2. When opening and closing the door, or taking the test object from the furnace, do not let the items touch the rubber edge of the gate. This will prevent the rubber edge from being damaged and will make it wear out faster.
3. Keep the ground around and at the bottom of the machine clean at all times. This will prevent accidents and keep too much dust from getting sucked into the machine.
4. Cooling system is the core of the machine, so inspect all copper pipes once a year for leakage. Notify the company or deal with it directly if there is a leaky in an oil or loudspeaker joint, or a welding port.
5. Clean and repair the high current contacts of the switchboard at least once a year. Loose contacts make the machine dangerous. They can burn the components or cause fire, alarm, or injury. Use the vacuum cleaner to suck out the dust inside.
6. Clean the humidifier and water trays often. This prevents scale, which blocks the steam. Generally, clean after each test. Remove scale timely extends humidification tube life, and ensures smooth water flow. Use copper brushes with water.
7. Clean wet cloth frequently. Hold on when the test cloth surface is not clean or hardened, or under the high heat above 85 ℃ control. Replace the cloth not absorbing water. Do this once every three months. It will improve moisture measurement accuracy. Use a clean cloth to wipe the heat-measuring body using clean hands, and then clean the sink.
8. Inspect and adjust the wet bulb’s water level. Keep the accumulation cylinder at the proper water level. Avoid too much or too little water. These can make the wet ball test cloth soak up water wrong and mess up the wet ball’s accuracy. Keep the water level at about sixth scale. Adjust the screws in two side of the water accumulation box to adjust its water level.
9. Do not debug the set values of two over-heat protectors in the distribution box at random. The values have been adjusted before the factory. A switch protects the heating and humidification tube. It stops empty burning and water shortage. Set point = heat set point +20 ℃ ~ 30 ℃
When the machine is running, the set point of the overheat protector on the panel = heat set point +15℃～20℃. The heater stops as the chamber reaches the set temperature. Then, the “OVER HEAT” alarm turns on. If it runs long and unattended, make sure the over-heat protector is set. Do this before the operation.
10. Water line inspection and maintenance. Water pipes is easy to plug and leak, so check it regularly whether there is water leakage and plugging. If any, promptly eliminate or notify the company. Replace the humidifier’s water once a month. This ensures good water quality and flow.
11. To remove the product when the test is done, make sure the machine is off. Also, make sure the operators wear dry, electric, temperature-resistant gloves.
12. Internal and external cleaning and maintenance. Remove the internal impurities before operating the machine.
13. Clean the distribution room at least once a year using a vacuum cleaner to remove the dust inside. Wipe it externally at least once a year with soapy water.
