Description

This invention relates to an air conditioner. Patent Document 1 discloses a built-in air conditioner installed in the ceiling space of a building, which draws in air, performs heat exchange, and blows it into the room via a discharge duct. This built-in air conditioner has a unit body installed in the ceiling space of the building, housing an indoor heat exchanger and a blower inside. An intake port is provided on the bottom or rear of the unit body, and a pair of support rails are detachably attached to the periphery of the intake port, on opposite sides. An air filter is detachably fitted onto the pair of support rails from the side of the unit body. According to the built-in air conditioner disclosed in Patent Document 1, the air filter can be removed from the unit body relatively easily by sliding it along the support rail. Furthermore, after removing dust and debris from the filter portion of the air filter, the air filter can be reinserted by aligning it with the support rail. In this way, the air filter can be attached and detached with relatively little effort.
