Multi compartment formaldehyde release rate constant temperature and humidity chamber formaldehyde test specimen pre-treatment chamber KELUTE

The test chamber is divided into: insulation shell, constant temperature chamber, combined working chamber, equipment chamber, etc. from the outside to the inside.
1. Insulation shell: Metal shell, filled with polyurethane and other insulation materials, with good insulation to prevent energy loss in the test chamber. At the same time, it isolates the impact of the environment on the working chamber and ensures smooth operation of the equipment.
2. Thermostatic chamber: A sealed space formed by the insulation shell, in which the working chamber is placed, and the temperature is indirectly controlled by controlling the temperature of the air.
3. Working compartment: made of inert and smooth mirror stainless steel with good sealing performance. Seal with clean materials such as expanded polytetrafluoroethylene and maintain a certain micro positive pressure to prevent external pollution from entering.
4. Equipment warehouse: Place monitoring devices, temperature control devices, humidity control devices, gas supply components, filtration and purification systems, circuit components, etc.

1. Multi compartment formaldehyde VOC pretreatment cabin air supply system: Cabin air circulation direction: ceiling - indoor - filtering device - upper air duct of the unit, and then flows through small holes in the ceiling to achieve uniform airflow. The air flow power is provided by the internal motor of the unit. Due to different working conditions, the test chamber can set intake frequency conversion to adjust the intake air volume according to different working conditions, achieving energy-saving goals.
2. Fresh air system: The system uses an intake fan to extract air from outside the cabin and enter the cabin. The air inside the cabin is automatically discharged from the exhaust port under pressure, and the fan motor meets energy-saving and environmental protection requirements.
3. Air filtration system: a three-level filtration device installed in the circulating air duct to ensure that the VOC background value inside the box is lower than the design value. The service life of the filter material is 3 years (calculated as 8 hours per day for 360 days), and a filtration schematic diagram is required. The core filter material needs to provide air efficiency certification materials
4. Wind speed control and fresh air (air exchange rate) inside the box: Adopting the ceiling top integrated orifice plate air supply technology, ensuring a large area of low wind speed air supply and large air exchange rate. The surface wind speed of the measured object inside the box is less than 0.3m/s, and a forced air exchange port is used, with an air exchange rate greater than 300m ³/ H.
