The invention relates to a seawater air-conditioning system with a fan (6) for generating an airflow (6), a humidifying device (7) for humidifying the airflow using mineralized water (3), in particular salt water, and a UV light source (12), wherein the seawater air-conditioning system is improved with respect to the effectiveness of the room climate generated by the seawater air-conditioning system and produces conditions which substantially approximate the actual oceanic climate in particular. According to the invention, the airflow (6) can flow through the humidifying device (7), and the humidifying device is arranged in the flow direction a climate chamber (11) is provided which adjoins the humidifying device (7) and is arranged downstream of the humidifying device (7) in the flow direction and the UV light source (12) is arranged such that the UV light source emits UV light to the humidified airflow (6) flowing through the climate chamber (11) and the humidifying device (7) surface (7) which faces the climate chamber (11) and through which air flows.本發明涉及一種海洋氣候空調裝置,其具有用於產生空氣流(6)的風扇(6)、用於利用礦化的,尤其是含海鹽的水(3)對空氣流進行加濕的加濕裝置(7)以及UV光源(12),該海洋氣候空調裝置在由其產生的室內氣候的功效方面得到改進且尤其實現了顯著更接近真正的海洋氣候的條件,為了實現該海洋氣候空調裝置,根據本發明提出,加濕裝置(7)能被空氣流(6)穿流且沿流動方向佈置;設有與加濕裝置(7)鄰接的且沿流動方向佈置在加濕裝置(7)之後的模擬氣候室(11);UV光源(12)如此佈置,使該UV光源以UV光照射穿流模擬氣候室(11)的、被加濕的空氣流(6)以及加濕裝置(7)的朝向模擬氣候室(11)的、空氣穿流的表面(7)。1‧‧‧海洋氣候空調裝置2‧‧‧殼體2‧‧‧下部殼體3‧‧‧含海鹽的水4‧‧‧空氣入口4‧‧‧篩檢程式5‧‧‧空氣出口6‧‧‧通風機6‧‧‧空氣流7‧‧‧鹽浴單元7‧‧‧表面8‧‧‧泵9‧‧‧管線10‧‧‧分配溝槽11‧‧‧模擬氣候室11‧‧‧中央區域12‧‧‧UV燈13‧‧‧離子化裝置14‧‧‧蓋
