[Problem to be solved by the invention]

Since the conventional built-in air conditioner is configured as described above, it is possible to install it in the space between 1 and 2.

It cannot be installed for a width of 3 feet, and the suction port is located at the back of the air conditioner, so in addition to the air inside the room, it can also draw air from inside the ceiling from gaps in the ceiling material. Sisters,
There were problems such as the inability to accurately measure temperature.

In addition, when performing service work such as inspection or maintenance on conventional built-in air conditioners, the installed drain piping and refrigerant piping must be removed, the main unit must be removed once, and the unit must be lowered to the floor from within the ceiling or inside the top bag. There was a problem in that servicing had to be done from the top and back of the main unit, making it a time-consuming task.

Furthermore, in conventional recessed air conditioners, materials such as sheet metal corresponding to the top and back suction ports are wasted, and the areas around the top and back suction ports are weak in strength. There was a problem that the blower chamber of the main body could be deformed or destroyed.

The recessed air conditioner of the present invention has been developed to solve the above-mentioned problems, and is capable of being installed in widths of three feet and three feet, and can also be installed recessed in the ceiling. In addition, the purpose of the installation is to provide a diversified built-in air conditioner that enables accurate temperature detection.

Furthermore, the purpose is to enable service from the back side, top side, and bottom side of the air conditioner main body, depending on the installation location.
