The same oxygen generator will have different performance in different environments, because a suitable environment can exert the performance of the oxygen generator, and an unsuitable environment will reduce the performance of the oxygen generator and increase the cost of production and consumption. Specifically, the environment in which the oxygen generator is located has four factors that need to be carefully considered, including atmospheric pressure in the air, ambient temperature, atmospheric humidity and carbon dioxide. 1. The influence of atmospheric pressure will increase the compression ratio of the air compressor. If the atmospheric pressure decreases by 001MPa, the compression ratio of the air compressor will increase by 6%~8%, and the compression energy consumption will increase. In addition, the reduction of atmospheric pressure will reduce the displacement of the air compressor, the corresponding oxygen production will also decrease, and the power consumption of the oxygen generator will also increase. 2. When the ambient temperature increases, the displacement of the air compressor will also decrease, which means that the shaft power will increase. The data shows that for every 3°C increase in ambient temperature, the shaft power increases by about 1%. At the same time, the increase of the ambient temperature will also lead to the increase of the exhaust temperature of the air compressor, which requires more cooling capacity to balance the cooling loss, and ultimately leads to an increase in energy consumption. 3. The influence of air humidity means that the humidity in the air is high, and the air compressor will consume more power when dealing with water vapor, thereby increasing the energy consumption of the air compressor. 4. The influence of impurities in the air Excessive impurities in the air will increase the purification load of the molecular sieve adsorber; if the purified air still fails to meet expectations, it will also affect the production efficiency of the subsequent system and the production quality of oxygen.
