In　order　to　investigate　the　performance　of　this　new　kind　of　air　conditioner,　its　principle　is　discussed.　At　the　same　time　the　effects　influenced　the　performance　of　the　filler　are　fully　discussed.　With　the　sychrometric　chart,　the　air　handling　process　is　analyzed.　The　experiment　data　corresponding　to　different　weather　conditions　are　given　at　the　same　time.　The　results　showed　that　the　effects　of　cooling　and　humidifying　of　this　air　conditioner　are　perfect,　and　its　application　prospect　is　favorable.
