[0002] The function of the ship's environmental control system is to maintain specific environmental parameter conditions in the cabin atmosphere, ensure the normal operation of various types of ships and offshore engineering platform equipment, and provide good working and living conditions for the crew.

[0003] With the rapid development of the shipping industry, crew members have higher and higher requirements for the quality of cabin atmospheric environment, and are paying more and more attention to the presence of harmful gas molecules (such as hydrogen sulfide, ammonia, methane, ozone, etc.) and odor molecules (such as foot odor, sweat odor, body odor, feces odor, and stench) in the cabin atmosphere. Summary of the invention

[0004] The technical problem to be solved by the present invention is: at present, most of the existing ship environmental control systems filter, adsorb, dilute, destroy, and cover up pollutants and odor molecules in the cabin atmosphere by adding conventional physical and chemical technical means such as high-efficiency filters, electrostatic adsorption devices, and releasing air fresheners and deodorants. The treatment process is often accompanied by secondary pollution, and the treatment effect is relatively limited. The released chemical molecular agents are not conducive to the health of the crew; in addition, the existing ship environmental control systems often rely on the crew's subjective judgment of whether there are harmful gas molecules and odor molecules, as well as the intensity, as the input conditions of the environmental control system, which is highly subjective and not representative.
