The present invention relates to the technical field of air resource utilization, and in particular to an integrated air water intake and oxygen-enriched air conditioning system and its operating method. The present invention provides an adsorption air water intake and temperature-swing adsorption oxygen-enriched air conditioning integrated system driven by a coupled heat pump and a solar thermal collection module. Compared with direct condensation water intake, adsorption water intake has a wider range of applicable conditions and lower energy consumption, while temperature-swing adsorption oxygen enrichment has lower energy consumption and convenient operation and maintenance compared with oxygen production by electrolysis of water. The present invention couples a heat pump and a heating module to jointly drive the adsorption air water intake and temperature-swing adsorption oxygen enrichment process, which has the advantages of energy saving and high efficiency. The front-to-back coupling arrangement of the adsorption air water intake and temperature-swing adsorption oxygen enrichment process is conducive to eliminating the influence of water vapor in the air on the competitive adsorption of oxygen during the adsorption process, improving the oxygen enrichment efficiency, and realizing the all-weather simultaneous production of fresh water and low-concentration oxygen-enriched air using air, meeting the needs of fresh water supply and indoor oxygen-enriched environment. The system is energy-saving and environmentally friendly, and the operation and maintenance are simple and reliable.
