Abstract: A ducted air conditioner includes a housing, a heat-retaining and drainage assembly, a fan assembly and an air conditioning device. The heat-retaining and drainage assembly is disposed in the housing, and includes a first heat-retaining member and a second heat-retaining member. The first heat-retaining member includes a first dividing plate. The second heat-retaining member is stacked with the first heat-retaining member, the second heat-retaining member includes a second dividing plate connected to the first heat-retaining member. An inner space of the housing is divided to a first cavity and a second cavity, an arrangement direction of the first cavity and the second cavity is perpendicular to a stacking direction of the first heat-retaining member and the second heat-retaining member. The fan assembly is disposed in the first cavity. The air conditioning device is disposed in the second cavity, and located between the first heat-retaining member and the second heat-retaining member.
