Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an air conditioner, and more particularly to a package air conditioner type air conditioner.

[Conventional technology]

Second as the air conditioner that has already been proposed.
The one shown in the figure is known. That is, the air conditioner has a structure including an conditioned air supply port 1, a return air receiving port 2 and an outside air intake port 3, and these air conditioning air supplying port 1, return air receiving port 2 and outside air intake port 3 are provided. Are connected to an air conditioner casing 7 via an air supply duct 4, a return air duct 5 and an outside air intake duct 6, respectively. Further, a cold / hot water coil 8 is arranged inside the air conditioner casing 7, and a blower 9 is arranged so as to be located below the air supply duct 4.

[Problems to be solved by the device]

However, the air conditioner provided with the conventional cold / hot water coil type cooler has the following restrictions in its structure.

(I), in order to use cold water or hot water by an external structure,
Requires external cold heat source manufacturing equipment.

(Ii) If the number of indoor air conditioners increases, a machine room for storing the air conditioners is required.

(Iii) It is difficult to deal with the extension of the machine room.

The purpose of the present invention is to eliminate the above-mentioned limitations of the prior art. It does not require cold and hot water of an external structure, and additionally needs a machine room to store even if the number increases indoors. There is not to provide an air conditioner.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides an air conditioner having an air conditioning air supply port, a return air receiving port, and an outside air intake port, in which a predetermined air conditioning is provided in the middle of a ventilation path formed in an air conditioner casing. This is a configuration in which a packaged air conditioner having a capacity and a blowing capacity is arranged.

[Action]

As described above, according to the present invention, since the packaged air conditioner having the predetermined air conditioning capacity and the air blowing capacity is provided in the middle of the air blowing path, it is not necessary to use cold water or hot water manufactured by the outside. Further, since the packaged air conditioner has a cooler and a blower built in as a unit, even if the number of indoor units increases, it is not necessary to provide a machine room for storing them.

〔Example〕

Hereinafter, the details of the present invention will be described with reference to the embodiments shown in the drawings.

FIG. 1 shows an embodiment of an air conditioner according to the present invention, which is an air conditioner with a built-in packaged air conditioner and has an air conditioning air supply port 10, a return air inlet 11 and an outside air inlet 12. ing. The outside air intake 12 is provided at a predetermined position on the right side surface of the air conditioner casing 13, and communicates with the return air and outside air mixing chamber 14 provided in the air conditioner casing 13. The return air / outside air mixing chamber 14 is connected to the return air inlet 11 via a return air duct 15.

Further, in the air conditioner casing 13, a package air conditioner chamber 16 is provided adjacent to the outside air mixing chamber 14, and two package air conditioners 17 are installed in the package air conditioner chamber 16. There is. The packaged air conditioner 17 incorporates a cooler and a blower required for the air handling unit as a unit. An external air inlet 19 is provided in a partition wall 18 provided between the packaged air conditioner chamber 16 and the external air mixing chamber 14.

On the other hand, a supply chamber 20 is arranged above the package air conditioner chamber 16, and a medium performance filter 22 and a re-use filter 22 are provided in a filter chamber 21 provided adjacent to the package air conditioner chamber 16 and the supply chamber 20. A thermoelectric heater 23 is arranged. In addition,
The filter chamber 21 is connected to the conditioned air supply port 10 via an air supply duct 24, and the air supply duct 24
A high-performance filter 25 is arranged in the middle of.

As described above, in the apparatus of this embodiment, the outside air mixing chamber 14, the package air conditioner chamber 16, the supply chamber 20, and the filter chamber 21 form a ventilation path. Of course, the blower of the packaged air conditioner 17 must satisfy the air volume and static pressure, and the cooling capacity must satisfy the air conditioning load.

This embodiment eliminates all the restrictions of the above-mentioned conventional technology.

In addition, in the above-described embodiment, the outdoor type is used to store two packaged air conditioners, but the present invention is not limited to this. An indoor type, a single type, a vertical type,
It can be freely configured such as a horizontal type.

[Effect of device]

As described above, according to the air conditioner of the present invention, a packaged air conditioner having a predetermined air conditioning capacity and a predetermined air blowing capacity is arranged in the middle of the air blowing path formed in the air conditioner casing. There is no need to use cold water or hot water produced by external production as in the conventional case, and therefore an external cold heat source production apparatus can be eliminated. In addition, since the packaged air conditioner has a structure in which a cooler and a blower are built in as a unit, even if the number of indoor air conditioners increases, there is no need to separately provide a machine room for accommodating as in the conventional case.

As described above, according to the device of the present invention, it is possible to eliminate the restriction of the above-mentioned conventional technique and to provide an air conditioner that satisfies the function promptly after planned design.
