Audited Supplier Scope of application
The vehicle environmental modeling laboratory can reproduce natural conditions and simulate environmental temperature and humidity, sunshine intensity, rain corrosion, driving road conditions, exhaust emissions and fresh air supply. It is of great significance to automobile development, performance evaluation and quality inspection. This system can be used to complete engine cooling tests, air conditioning system development, hot and cold emission tests, heating system development, hot and cold start tests, defrosting and defrosting tests, etc., which can improve the comfort, safety and reliability of automobiles and accessories. Continuously improve to provide an effective platform.
Equipment Features The test cabin is mainly composed of cabin protection structure, air conditioning system, fresh air system, dynamometer system, exhaust emission system, and solar irradiation system.
1. Adopt advanced cold end balance control and PID automatic adjustment technology to achieve energy saving of more than 30% at high and low temperatures and constant temperature.
2. The compressors and accessories of the refrigeration system are all made of internationally renowned brands with long-lasting and reliable operation, excellent workmanship, low failure rate, and environmentally friendly refrigerants, which comply with the requirements of international environmental protection conventions.
| Inner box size (WxHxD) cm | 400X300X700 |
| Temperature range | -40~+80°C |
| Temperature change rate | 25°C←→-40°C, 2.5 hours (no load, average over the entire process) 25°C←→60°C 2 hours (no load, average over the entire process) |
| Temperature control accuracy | ±1°C (measured at the control point, when there is no heat load change)/±1.2°C (measured at the control point, when conducting an emission test) |
| Temperature and humidity deviation | ±2°C (without heat load change)/+3.0%RH (>75%RH) ±5.0%RH (<75%RH) |
| Humidity range | 10%~95%RH |
| Humidity uniformity | ±3.0%RH (no load) |
| Humidity fluctuation | ±2.0%RH |
| Fresh air system | When the ambient temperature is 0ºC~-40ºC, the air volume is greater than 700m?h. When the ambient temperature is 20ºC, the air volume is greater than 2500m'/h. The fresh air blower is a variable frequency motor, and the fresh air unit has a manual switch and Air volume adjustment function. |
| Automobile exhaust emission system | Provide stainless steel variable frequency fans, pipelines from the cabin to the outdoors and exhaust back pressure control devices so that the static pressure at the outlet of the exhaust pipe during the entire test does not exceed ±1.25 kPa (meeting GB18352.2-2001); the maximum Exhaust air extraction volume, 4000m'/h. |
| Air conditioning system | |
| Refrigeration method | Vapor compression refrigeration |
| Circulation fan | Vapor compression refrigeration |
| The whole frame | Circulating air flow is approximately 150.000 mi/h |
| Floor construction | The overall environmental test chamber has a three-dimensional layout of upper and lower floors. The lower floor is the environmental cabin and the upper floor is the circulating air duct. 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 |
| Fulfill the standard | 70/220/EEC, 715/2007/EC and 692/2008/ECEPA Tirel, NLEV and Tire2GB 18352.2, GB18352.3, HJ/T400-2007 and HJ/T390-2007, National 5 regulations |
| Remark | Different vehicle sizes can be customized according to needs |
