The hydrogen-related environmental chamber adopts functional modular design, is explosion-proof and anti-static, and meets relevant test standards. The product has high reliability and comprehensive safety warning features, and is suitable for testing stacks and fuel cell engine systems. Applicable to fuel cell systems with a maximum power of 150KW, low temperature tests (storage, starting, performance), high temperature tests (storage, starting, performance), and damp heat tests (high temperature and damp heat)
The working process of the hydrogen leakage environmental chamber of hydrogen energy vehicles is as follows:
1. Environmental parameter detection:
- Each detection module monitors environmental parameters inside the environmental chamber, including smoke, fire, temperature, and hydrogen concentration.
- Obtain environmental parameters and transmit them to the detection unit.
2. Communication detection:
- The communication detection subunit monitors the data communication between the bench and the environmental chamber to ensure smooth communication.
3. Fault detection:
- The fault detection sub-unit monitors each fault module, including the fault conditions of various equipment in the bench and test cabin, such as over-temperature, circulating fans, refrigeration devices, humidifiers, etc.
4. Safety management execution:
- Execute corresponding safety management instructions based on the monitored environmental parameters and fault conditions.
- The sound and light alarm control module issues green light indication, yellow light alarm or red light alarm according to the situation, and reminds through sound alarm.
- The exhaust fan control module adjusts the ventilation conditions to keep the air in the cabin fresh.
- The in-cabin equipment control module opens, closes or adjusts the equipment as needed.
- The hydrogen supply control module regulates the supply of hydrogen according to the hydrogen concentration.
- The carbon dioxide fire extinguishing control module activates the fire extinguishing system when necessary.
- The bench control module performs relevant operations based on the monitored data.
5. Security management strategy:
- Execute corresponding safety management instructions according to the security policies of the environment detector, communication detector and fault detector.
- Ensure that timely measures are taken to ensure the safety and stability of the environmental test chamber based on the detected data.
Through the above safety system, users can feel more at ease during the test process. If you have any other test questions, you can consult the relevant technical personnel of "Environmental Instrument".
1. Built-in or external main cold start temperature control test device to reduce cold start test time.
2. Built-in or external auxiliary cooling temperature control test device.
3. According to user requirements, the intake and exhaust plateau low pressure simulation system is optional.
4. Thermal balance capability: loading time 5~10min.
5. Dynamic return time of fuel cell thermal equilibrium state: <2min.
