[0002] Multi-split PSA oxygen generator is also called pressure swing adsorption oxygen generator. Its function is to obtain oxygen with higher purity. Generally, oxygen generator units using PSA oxygen generation method are multi-split to supply oxygen to offices, bedrooms, study rooms and other rooms. The oxygen generator units are installed in a separate machine room. The working environment of the PSA oxygen generator requires a temperature not exceeding 40 degrees Celsius and a humidity not exceeding 80%. When the oxygen generator is turned on and running, a large amount of heat generated by the operation of the internal air compressor will be discharged through the exhaust port. This part of heat will cause the ambient temperature around the oxygen generator to rise. After continuous accumulation, it will exceed 40 degrees Celsius, which will also cause the oxygen generator to age faster or shut down.
[0003] Therefore, in the fresh air exhaust and heat dissipation device of the multi-split PSA oxygen generator, it is necessary to ensure the temperature and humidity balance in the machine room to allow the PSA oxygen generator to operate normally, so a fresh air system is needed to control temperature and humidity.
