An indoor unit includes a housing, an air duct member, and a thermal insulation tube. The housing has an accommodating cavity. the air duct member is detachably mounted in the accommodating cavity. A mounting space is formed at a side of the air duct member in a length direction of the air duct member. The mounting space has a mounting opening facing an outside of the housing. The thermal insulation tube includes a tube section extending along a direction perpendicular to the length direction of the air duct member. The tube section is at least partially arranged in the mounting space.

An ember and flame resistant resettable automatic soffit vent includes a tray with ventilation openings formed in its floor. A mesh screen resides on the floor of the tray spanning the ventilation openings. A flat slide resides atop the screen and also has ventilation openings that match those of the tray. The slide has an open position wherein its ventilation openings align with those of the tray to allow airflow through the vent and a closed position wherein its ventilation openings are misaligned with the ventilation openings of the tray to close off airflow through the vent. The vent can be manually moved between its open and closed positions and one or more tension springs and a thermal link assembly cooperate to move the slide to its closed position if the vent is exposed to a high temperature cause by a fire very near a home. The vent also can be manually closed by a homeowner when a fire is threatening and then manually reopened when the fire threat passes without destroying the automatic closing feature of the vent.

An air diffuser configured to be positioned in a raised floor, in which the air diffuser includes a sleeve having a first end and a second end with an air flow passage extending through the sleeve from the first end to the second end, a diffuser face disposed at the first end of the sleeve and configured to be exposed to an environment in an installed position within the raised floor, a damper disposed at the second end of the sleeve, and a plenum chamber defined within the sleeve between the damper and the diffuser face.
