Automotive vehicle environment experimental warehouse:
The high and low temperature and humidity environment test cabin of the vehicle is based on the working condition of the vehicle (car, light truck) environmental test performance test. After heat insulation treatment, appropriate ventilation and air conditioning equipment are used to meet the vehicle power matching and economic performance matching. , Vehicle cold start performance matching, vehicle air conditioning performance development, vehicle low temperature adaptability performance, emission performance and other test requirements.
The high and low temperature and humidity environment experimental cabin of the whole vehicle must change according to a certain curve during operation to simulate the changes in temperature and humidity in severe weather. The temperature inside the cabin is between -40 ° C and 60 ° C, and the humidity range is between 10% and 90%. The internal environment of the car's high and low temperature and humidity environment is complicated, and the temperature and humidity are quite different. In addition, due to the large amount of electrical equipment required for the experiment, the benches in each experiment room contained a large amount of oil, diesel, and dangerous gases. These were flammable, explosive, and relatively concentrated. Once these items are burned, they will soon form a fire. If they are not controlled in time, they will ignite the car in the cabin and the corresponding fuel pipeline even explode, which is very dangerous. Nianhai Fire Fighting Co., Ltd. has set up a complete set of high- and low-temperature environment experimental cabin gas fire protection system for the whole vehicle in view of the particularity of the high- and low-temperature humid and hot environment experimental cabin of the entire vehicle.
What we do for our customers:

The system has a high degree of integration and good results, and has systematically analyzed the possible occurrences;
2. According to the on-site conditions of the high-low temperature environment experimental cabin of the vehicle, the fire alarm system is equipped with four sets of enhanced infrared flame detectors in each protective area, and two alarms are adopted, which are controlled by the gas fire controller. The fire source can be detected quickly, accurately and effectively, and the fire disaster can be extinguished in the initial stage.
3. After the installation of the complete gas fire extinguishing system, Nianhai Fire Fighting provided system commissioning and formulated a special automotive high and low temperature humid heat environment experimental cabin gas fire fighting system training program and manual, and conducted many trainings and site operations for operators. Simulate operation, provide telephone guidance in the later stage, and truly achieve the "customer first" service concept.
