|
Fresh air system |
When the temperature of the environmental chamber is 0℃--40C, the air volume is greater than 700m/h, and when the temperature of the environmental chamber is 20℃, the air volume is greater than 2500m*/h. The fresh air blower is a variable frequency motor, and the fresh air unit has manual switch and air volume adjustment functions. |
|
Automobile exhaust emission system |
Provide stainless steel variable frequency fan, pipeline from inside to outside of the cabin and exhaust back pressure control device, so that the static pressure at the outlet of the exhaust pipe does not exceed ±1.25kPa (meeting GB18352.2-2001) during the whole test process; the maximum exhaust air extraction volume is 4000m/h. |
|
Air conditioning system |
|
|
Refrigeration method |
Steam compression refrigeration |
|
Circulating fan |
Circulating air flow rate is about 150,000 m/h |
|
Overall structure |
The environmental test chamber is a three-dimensional layout with upper and lower layers, the lower layer is the environmental chamber, and the upper layer is the circulating air duct. |
|
Floor structure |
The design structure is basically the same as the wall. In addition, an anti-slip layer and a pressure plate are added. |
|
Anti-slip stainless steel thickness |
≥3mm |
