Temperature environment test
In high temperature environments, such as 40℃ and above, the Portable Oxygen Concentrator With Battery faces many challenges. Some tests found that the electronic components of some devices may have overheat protection activated, resulting in a brief shutdown. However, more advanced models can continue to operate for a long time in high temperature environments by optimizing the heat dissipation design, such as adding heat sinks or using special thermal conductive materials. However, the oxygen output concentration may fluctuate slightly, and the fluctuation range is generally within ±3% of the set concentration. In low temperature environments, such as -10℃, the battery performance decreases significantly, the battery life is shortened by about 30%-50%, and the device startup time is extended. Some molecular sieves may have reduced adsorption efficiency due to low temperature, making the initial oxygen output concentration slightly lower than the standard value, but after the device is preheated for a period of time, it can gradually resume normal operation, and the overall reliability can still meet basic needs.
Humidity environment test
In high humidity environments, when the humidity reaches more than 90%, moisture may condense inside the device, affecting electrical connections and molecular sieve performance. Tests show that about 20% of ordinary devices will have intermittent failures caused by humidity, such as unstable oxygen flow or increased concentration deviation. However, high-end products with waterproof and moisture-proof design can effectively resist the influence of high humidity through sealing treatment and the use of desiccant, and the stability of their oxygen output parameters can be maintained at a high level, and the probability of failure caused by humidity is less than 5%. In low humidity environments, such as the humidity below 20% common in desert areas, the main problem of equipment is static electricity accumulation, which may interfere with electronic control systems, but through the improvement of static electricity protection measures, most equipment can operate normally and reliability is less affected.
Altitude environmental test
As the altitude increases, the air becomes thinner. At an altitude of 2,000 meters, the oxygen output flow of some Portable Oxygen Concentrator With Battery will decrease by about 10%-15% because the amount of air entering the device is reduced. At an altitude of 4,000 meters, about 30% of the equipment needs to adjust the working parameters to maintain a stable oxygen output concentration, and the battery consumption rate is accelerated, and the battery life is shortened by about 20%. However, products designed specifically for plateau areas have better reliability in high-altitude areas by improving the air intake system and optimizing the pressure compensation algorithm. The changes in oxygen output concentration and flow rate can be controlled within a small range, which basically does not affect the user's normal oxygen inhalation needs.
Bump and vibration environment test
In the bump and vibration environment test simulating transportation or daily carrying, the fixation of the internal components of the equipment is tested. About 15% of the equipment will have loose internal pipes or displacement of connecting parts after long-term high-intensity bumps, resulting in oxygen leakage or unstable output. However, products with seismic design, such as adding cushions and strengthening internal structures, have greatly improved reliability in bumpy and vibrating environments. After tests equivalent to long-distance transportation or outdoor rugged road conditions, they can still work normally, and the proportion of various performance indicators that meet the requirements can reach more than 90%, effectively ensuring the safety and effectiveness in mobile use scenarios.
