1. Automatic electronic flow control: Adopting high-precision and fully automatic electronic flow meters from the United States to control the intake, automatically detecting and feeding back flow losses and timely replenishing flow, the flow control is precise and efficient. Circulating air system: All edges and corners in the test cabin are made into a certain arc, and a full cross-section circulating air system is used to horizontally pass through the entire cabin to avoid any dead corners and ensure uniform distribution of indoor temperature and humidity.
2. Formaldehyde online detection function: The climate box adopts high-precision formaldehyde detection sensors imported from the United States, with a minimum reading value of 0.001ppm. The collection frequency can be set arbitrarily, and the formaldehyde concentration in the cabin can be measured and recorded in real-time.
3. Intelligent touch screen controller: Using UNIQUE LCD touch screen controller from Japan, parameters such as temperature, humidity, dew point temperature, working time, and gas flow can be set through the touch screen; Automatically calculate and control the dew point temperature; Real time display of temperature, humidity, dew point temperature, working time, gas flow rate and other data;
Store and export temperature, humidity, time and other data; Historical fault query and historical data playback function; Various functions such as permission settings, appointment for startup, etc.

VOC detection environment climate warehouse structure
A chamber made of chemically inert materials that can be used to test the release of volatile organic compounds (VOCs) in coatings. It consists of a sealed chamber, an air filter, an air temperature and humidity control and monitoring system, a flow control device, and an air sampling system. The environmental testing chamber has a volume of 20L to 1000L.

The environmental testing cabin can refer to the following technical parameter requirements:
a) Cabin temperature: 20 ℃~40 ℃, fluctuation ± 1 ℃;
b) Relative humidity of the cabin air: 40%~60%, with a deviation of ± 5%;
c) Ventilation rate inside the cabin: 0.5 to 2.0 times/h;
d) Air velocity near the surface of the specimen: 0.1 m/s~0.3 m/s;
e) The cabin leakage air volume is less than 5% of the air supply volume;
f) The cabin should meet a positive pressure of 10 Pa ± 5 Pa;
g) The background concentration of total volatile organic compounds (TVOC) shall not exceed 50 μ G/m3, with a single target volatile organic compound background concentration not exceeding 5 μ G/m3;
h) The average recovery rate of toluene and dodecyl alcohol ester (2,2,4-trimethyl-1,3-pentanediol and its isomers) shall not be less than 80%.

1. Energy saving design: This equipment adopts energy-saving design in the two major energy consumption parts of gas supply and refrigeration, using Roots blower for gas supply, with high gas supply volume, low energy consumption, and low noise. Adopting imported refrigeration compressors from France, oil-free, silent, low energy consumption, with a continuous working life of up to 7 years.
2. A comprehensive safety protection system: circuit system load protection, compressor load protection, control system load protection, humidification system load protection, over temperature load protection, and fault warning light. When abnormal conditions occur, the controller screen will automatically display the fault status, cut off the power source switch, and provide troubleshooting methods.
