[0038] The implementation principle of this application embodiment is as follows:

[0039] In actual use, the integrated water-cooled marine temperature-regulating and dehumidifying air conditioning unit compresses the refrigerant into a high-temperature, high-pressure gas via compressor 7. After condensation and heat release via water-cooled condenser shell and tube 8, the gas is sent to the upper layer 31 seawater corrosion-resistant heat exchanger 4 for evaporation and heat absorption, achieving air cooling and dehumidification. Water vapor in the air liquefies upon cooling and is discharged. When heating is required, explosion-proof electric heater 5 supplements the heating of the air. The treated air is then delivered into the cabin by explosion-proof blower 6 through vent 22. The unit adopts a layered structure with layered plates 3 for physical isolation, reducing vibration and noise interference. It also utilizes corrosion-resistant materials and explosion-proof design to adapt to the high salt spray and flammable / explosive environments of ships.
