Fan coil unit {FAN COIL UNIT}

The present invention relates to a fan coil unit having a heat exchanger device or a blower device.

Most of the conventional air conditioners, for example, a fan coil unit including a fan or a coil for heat exchange, have a configuration in which a heat exchange coil and a fan are fixed inside one casing. Therefore, there is a problem that the casing must be completely disassembled in order to remove the heat exchange coil and the fan, replace, inspect, and the like. In particular, in the so-called ceiling-mounted fan coil unit to be used on the ceiling, the entire fan coil unit may need to be lowered from the ceiling, which is more difficult.

In order to solve such a problem, Japanese Unexamined Patent Publication No. 2000-65387 proposes an air conditioner that can detach a ceiling plate from the ceiling side and improve maintenance.

However, there still remains a problem that the air conditioner of Japanese Patent Laid-Open No. 2000-65387 cannot remove, replace, or inspect a heat exchange coil or a fan unless the entire fan coil unit is lowered.

In addition, generally installed on one side of the fan coil unit, the operation of changing the position of the heat source entrance to the heat exchange coil and the heat source (for example, water, gas, etc.) to the opposite side, into the inside of the fan coil unit The operation of changing the position of the intake port for sucking air has a problem that very much effort and time are required once the fan coil unit is installed on the ceiling.

The present invention has been devised in view of the above circumstances, and an object thereof is that in a fan coil unit fixed to the ceiling, the blower or the heat exchanger can be replaced, inspected, replaced, and the like without falling from the ceiling, It is possible to simply change the position of the heat source entrance to the opposite side, and to provide a fan coil unit capable of easily changing the position of the suction port.
