Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air conditioning system that facilitates work when installing a blowing chamber on a floor.
[0002]
[Prior art]
Conventionally, in order to cool and heat a plurality of rooms, it is common to provide an air conditioner corresponding to each room. However, this requires a large number of air conditioners, which is uneconomical.
[0003]
Therefore, a multi-type air conditioner that performs air conditioning by providing an indoor unit in each room and supplying refrigerant from the single outdoor unit to the indoor unit has begun to be provided on the market.
[0004]
However, even in this multi-type air conditioner, the same number of indoor units as the conditioned rooms are required, and if the number of conditioned rooms is large, the total piping distance of the refrigerant pipes becomes long, so that the refrigerant is circulated. However, it is necessary to use an outdoor unit with a large capacity, and there is a problem of lack of workability and maintainability due to a complicated refrigerant piping route.
[0005]
From such a viewpoint, the applicant of the present application has proposed an air conditioner having a configuration as shown in FIG. 5 in Japanese Patent Application No. 9-618.
[0006]
The air conditioner includes a compressor (not shown) that compresses the refrigerant and the like, and is installed outside the outdoor units 20a and 20b, behind the ceiling, under the stairs, and the like to exchange heat between the refrigerant and room air. The indoor units 10a and 10b, the blowout chambers 60a and 60b for blowing the conditioned air provided in each conditioned room to the conditioned room, and the conditioned air in the indoor units 10a and 10b are supplied to the blowout chambers 60a and 60b. The ducts 100a and 100b for guiding are provided.
[0007]
The blowing chamber 60a is installed on the floor, and the blowing chamber 60b is installed on the ceiling.
[0008]
[Problems to be solved by the invention]
However, since the duct 100a is disposed under the floor, there is a problem in that workability is lacking because it is necessary to perform a predetermined operation under the floor when fixing the blowing chamber 60a to the floor.
[0009]
That is, in order to connect the duct 100a arranged under the floor to the blowout chamber 60a, it must be submerged under the floor, but since the attachment of the blowout chamber 60a is performed after flooring, it is difficult to dive under the floor. The work after diving with it becomes very difficult.
[0010]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an air conditioning system that can easily connect a blowout chamber and a duct and install the blowout chamber without diving under the floor.
[0011]
