In the conventional air conditioning unit, the installation space of the unit cannot be sufficiently secured due to the beams and the like, and when the ceiling must be lowered, or the duct piping space such as the start-up of the duct to the second or third floor is properly secured. Even if it is not possible, according to the configuration of the present invention, it is possible to install by separately installing according to each space. In addition, in the case where the air conditioning units 6 are divided into zones and the directions of the inlets and the outlets of the plurality of air conditioning units 6 are not aligned in the same direction due to the convenience of duct piping, etc., it is easy to orient the respective air conditioning units 6 in appropriate directions. It can be solved, and the degree of freedom of duct piping can be improved.

Further, the air-conditioning units arranged in a place such as a one-story house or a small-scale house where the air-conditioning unit alone is sufficient and where the capacity of a plurality of air-conditioning units is required or where zone separation is desired are air-conditioning units. Since it is only necessary to adjust the number of units and connect them, it is possible to make the units common to different capacities, and further connect the hot water inlet 11, the hot water outlet 12 and the terminal box 10 to the external supply port. If the configuration also serves as a connection part with another air conditioning unit, the configuration is simplified, and any air conditioning unit is common for connection of external supply or as another air conditioning unit connected to such Can be used for
Cost can be reduced by mass production.

Further, as shown in FIG. 3, when a plurality of air conditioning units 6 are combined, the cover 23 of the connecting surface between the units is removed and the air passages between the units are made to communicate with each other so that all the connecting ducts 17 etc. Even if it is not connected to the air conditioning unit 6, the airflow can be sent to each unit, and the duct piping does not become complicated. Further, in the hot water connection hose 24 that connects the hot water inlet 11 and the hot water outlet 12 to each other at a position that is recessed with respect to the connection surface of the air conditioning unit 6, the bellows hose portion is expandable and the nut is attached to the bellows hose. Since it is rotatable, it can be attached even after the air conditioning units 6 are combined, and it is not necessary to work while holding down the heavy air conditioning units.

When the air conditioning unit is fixed to a single unit, as shown in FIG. 2, the connecting portions 9 between the units on both sides of the unit are connected.
Each of them is fixed by a fixed support member, and in the case of two pieces, if sufficient strength can be secured, they are fixed at diagonal positions as shown in FIG. 3, and for other air conditioning units, between the connecting portions 9 between the units. It is possible to hold by connecting. In the above embodiment, the case of heating as the air conditioning unit was shown, but from the spirit of the invention, cooling, dehumidification, humidification,
It is obvious that it can be applied to all air conditioners such as ventilation.

Embodiment 2 of the Invention FIG. 5: is a block diagram of the air conditioning unit which shows other embodiment. The system configuration in which the present air conditioning unit is incorporated is similar to that of FIG. In the present embodiment, one of the air conditioning units 6 has substantially the same structure as that of the first embodiment, but the other air conditioning unit has a connection portion for supplying an external supply to another air conditioning unit. I haven't.

Further, the connecting portion 9 between the two units does not have a structure for connecting the air conditioning unit, except that the respective units can be connected. In the case where it is premised that the two are separated and connected in this way, the configuration can be simplified by providing each with only the necessary minimum configuration, so that the cost can be reduced and the configuration can be simplified. It is possible to make it easy to make a mistake during minute construction and assembly and to have good workability.

It is also possible to use each of the air conditioning units as an end unit and use the air conditioning unit of Embodiment 1 as an intermediate unit. In this way, the connection portion that is not used in the end unit is not exposed, which improves the workability and aesthetics. In the first and second embodiments described above, if the cover 25 that covers the hot water inlet 11 and the hot water outlet 12 is provided at the time of connecting the air conditioning unit as shown in FIG.
