PROBLEM TO BE SOLVED: To provide a cleaning/purification system formed by connecting communicably an air cleaner, a whole heat exchange type ventilator, and an ultraviolet sterilizer, though an interchangeable ventilation joint and a middle duct fan.SOLUTION: There is provided a system in which air filtered in a housing having a built-in air cleaner is subjected to temperature adjustment/humidity adjustment performed in a housing having a built-in whole heat exchange type ventilator, and then cleaned and purified in a housing having a built-in ultraviolet sterilizer. In the cleaning/purification system, each housing is connected communicably though an interchangeable ventilation joint, and a middle duct fan including the ventilation joint, to thereby complement/enhance each cleaning function carried by respective housings.SELECTED DRAWING: Figure 1【課題】空気清浄装置と、全熱交換型換気装置と、紫外線殺菌装置に、互換性を有する通気継手及び中間ダクトファンで連通接続した清浄・浄化システムを提供する。【解決手段】空気清浄装置内蔵の筐体で濾過した空気を、全熱交換型換気装置内蔵の筐体で調温・調湿し、紫外線殺菌装置内蔵の筐体で清浄・浄化処理するシステムで、それぞれの筐体に互換性を有する通気継手、及び通気継手を具備した中間ダクトファンで連通接続する事で、其々の前記筐体が持つ清浄機能を相補・拡充する事が可能な清浄・浄化システムである。【選択図】図1
