[0002]
[Prior art]
In general, a built-in type air conditioner in which a blowout duct is extended in a unit body that is installed in a ceiling space of a building and accommodates an indoor heat exchanger and a fan is known. In such a built-in type air conditioner, the air heat-exchanged by the indoor heat exchanger can be guided to the appropriate position in the room through the blowout duct and blown into the room, so that it is optimal without impairing the aesthetics of the room. Air conditioning can be realized.
[0003]
Conventionally, this type of built-in type air conditioner includes a panel specification built-in type air conditioner 10 and a duct specification built-in type air conditioner 20, as shown in FIG. The panel specification built-in type air conditioner 10 (FIG. 7A) is provided on the lower surface of the unit body 11 and sucks room air from the ceiling panel 12 installed on the ceiling plate. Arranged inside the main body 11. On the other hand, the duct specification built-in type air conditioner 20 (FIG. 7B) is provided with a suction duct 22 on the back surface of the unit main body 21 and sucks indoor air through the suction duct 22. It is installed on the outer surface of the side plate of the unit main body 21.
[0004]
[Problems to be solved by the invention]
By the way, in order to increase the capacity of the panel specification built-in air conditioner 10 and the duct specification built-in air conditioner 20, it is necessary to increase the size of the built-in indoor heat exchanger and fan motor. Therefore, the unit main bodies 11 and 21 that accommodate these devices are also increased in size. For this reason, the indoor layout, for example, may be hindered.
[0005]
An object of the present invention is to provide a built-in air conditioner that can cope with an increase in capacity in an installation space for one air conditioner.
[0006]
[Means for Solving the Problems]
The invention according to claim 1 is a built-in type air conditioner provided with a built-in type air conditioner that is installed on a ceiling portion of a building and has a blowout duct extended to a unit body configured to accommodate a heat exchanger and a fan. In the apparatus, the unit body of the built-in type air conditioner having the same capacity is configured by stacking a plurality of stages, and the built-in type air conditioner has a ceiling panel provided with a suction port installed at the bottom of the unit body. Only possible built-in type air conditioner, the ceiling panel is installed in the unit body of the bottom built-in type air conditioner, and the top panel of the unit body in the built-in type air conditioner other than the top level An opening is formed .
[0011]
The invention described in claim 1 has the following action.
[0012]
Since multiple units of built-in air conditioners with the same capacity are stacked, it is possible to realize a capacity that is more than that of two built-in air conditioners.
[0013]
Moreover, capacity control can be realized by individually controlling a plurality of built-in air conditioners stacked in a plurality of stages.
[0014]
In addition, since the unit bodies of multiple built-in type air conditioners are stacked, the installation space for one air conditioner is sufficient.For example, there is no hindrance to the installation of lighting, etc. Can be prevented.
[0015]
In addition, since multiple built-in air conditioners are stacked, it is possible to suspend multiple built-in air conditioners with four suspension bolts for one built-in air conditioner. Construction of the type air conditioner can be facilitated.
[0016]
In addition, since the unit bodies of multiple built-in type air conditioners are stacked, connection ports for the same type of piping such as refrigerant piping and drain piping exist in the same vertical plane. Piping can be installed in one piece.
[0017]
In addition, it is possible to increase the capacity by stacking unit bodies of the same capacity built-in type air conditioner, so there is no need to newly design a large capacity air conditioner. The cost can be reduced.
In addition, since the ceiling panel is installed only in the unit body of the built-in type air conditioner at the lowermost stage, the entire apparatus has one ceiling panel, and a large capacity can be realized at a low initial cost. Furthermore, since the ceiling panel provided with the suction port is a single device as a whole, the air cleaning filter can be arranged at one ceiling panel or in the vicinity thereof, so that the filter can be easily maintained.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0030]
[A] First embodiment (FIGS. 1 to 4)
FIG. 1 is a side view showing an embodiment of a built-in air conditioner according to the present invention.
[0031]
As shown in FIG. 1, a built-in air conditioner 100 is disposed in a ceiling space 34 of a building 31, and a unit of a duct-specific built-in air conditioner 40 on a unit body 35 of a panel-specific built-in air conditioner 30. The main bodies 35 are stacked. The panel specification built-in type air conditioner 30 and the duct specification built-in type air conditioner 40 are configured to have the same capacity (capability).
[0032]
Originally, these panel specification built-in type air conditioner 30 and duct specification built-in type air conditioner 40 are respectively independent of ceiling 32 and ceiling plate of building 31 as shown in FIGS. 2 (A) and 2 (B). The unit body 35, the blowout duct 36, and the electrical control box 37 for operation control are arranged by being suspended in a ceiling space 34 between the unit 33.

The box body 54 of the unit main body 35 has a top plate 39 at the upper edge portion of four side plates 38 that are arranged opposite to each other and provided in a square frame shape, and a drain pan presser plate 46 at a part of the lower edge portion. Fixed and configured. A heat insulating material is attached to the inner and outer surfaces, or the inner or outer surface (the outer surface in the present embodiment) of the side plate 38, the top plate 39, and the drain pan presser plate 46.
[0034]
A hanging metal fitting 41 is fixed to the side plate 38 of the box body 54 of the unit main body 35. The hanging metal fitting 41 is fixed to a hanging bolt 42 suspended from the ceiling 32 of the building 31, so that the panel specification built-in type air conditioner is attached. The machine 30 and the duct specification built-in type air conditioner 40 are configured to be suspended from the ceiling 32 of the building 31.
[0035]
The unit main body 35 is configured such that an indoor heat exchanger (not shown), a fan 56 (FIG. 1), and a fan motor are accommodated in a box body 54. The indoor heat exchanger uses a refrigerant pipe (gas pipe) connected to the refrigerant pipe connection port 43 shown in FIGS. 3 and 4 and a refrigerant pipe (liquid pipe) connected to the refrigerant pipe connection port 44. It is connected to an outdoor unit (not shown). The indoor heat exchanger 55 of the unit main body 35 cools or heats the air sucked into the unit main body 35 as will be described later by evaporation or condensation of the refrigerant guided from the outdoor unit.
[0036]
3 and 4, reference numeral 45A indicates a drain pipe connection port, and reference numeral 45B indicates a drain discharge port.
[0037]
2 is normally extended from the unit main body 35. As shown in FIG. Each of the blowout ducts 36 is fitted at one end to a blowout port 47 (FIGS. 3 and 4) integrally installed on one side plate 38A of the box body 54 of the unit main body 35, and a blowout grill 48 is attached to the other end. It is done. The blowing grill 48 is installed at an appropriate position on the ceiling board 33. The rotation of the fan of the unit main body 35 causes room air to be sucked into the unit main body 35 as will be described later, and the air heat-exchanged by the indoor heat exchanger is blown out from the blow grill 48 into the room through the blow duct 36.
[0038]
By the way, the panel specification built-in type air conditioner 30 shown in FIGS. 2A and 3 has a ceiling panel 49 fitted into the lower opening of the unit body 35.
