Abstract

PURPOSE:To enable a sufficient volume of fed air to be attained without increasing an opening in its diameter by a method wherein an air feeding passage extending from an outdoor suction port to a communication port of an indoor unit is formed between a sleeve and an outside part of a main body and a damper for use in changing-over between an opened state and a closed state of the communication port is arranged. CONSTITUTION:In case that a surrounding atmosphere is flowed through a surrounding atmosphere intake port 18 as indicated by arrow B, and passes through an air supplying passage 19 to flow through a communication port 20 so as to take the surrounding atmosphere, a damper 16 is kept opened, so that the air is induced from an opening part 15 into an indoor unit 6 by an indoor air blower 12. At this time, the air may flow in without being related to an air passage (indicated by arrow A) within the outdoor unit 5. The induced air is mixed with air flowed from an indoor suction port 11, the air is heated or cooled by an indoor heat exchanger 13 and a part of fresh air is blown out through an indoor blowing port 14 into a room together with conditioned air. In case that it is not necessary to take the surrounding air, the opening 15 is closed by the damper 15. With this arrangement, a sufficient volume of ventilation air can be attained and so it is not necessary to increase an opening in its diameter.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air supply device for an individual air conditioner installed in a perimeter zone of a building.

Conventional branch unit i Conventionally, the perimeter zone of a building is equipped with an individual air conditioner that air-conditions each room individually, and air-conditions according to the load of the room. The individual air conditioner has a configuration as shown in FIG.

i.e. a sleeve 2 fixed to a wall 1 of a building.
The main body 3 of the individual air conditioner is inserted and installed inside. The main body 3 is divided into an outdoor unit section 6 and an indoor unit section 6 by a partition plate 4. A flow path is formed in which outdoor air flows into the outdoor unit section 5 from an outdoor air intake lower, passes through an outdoor heat exchanger 8, and is blown out to the outdoors from an outdoor air outlet 1o by an outdoor blower 9. On the other hand, indoor air flows into the indoor unit section 6 from the indoor air intake port 11, and the indoor air blower 12 and the indoor heat exchanger 13 are
Heated or cooled air is blown out from the indoor blowout 14 after 1 hour. In order to ventilate the room, an opening 15 is provided below the partition plate 4, and a damper 16 is provided for opening and closing this opening 16. When it is desired to take in outside air, the damper 16 is provided.
The indoor air blower 12 is used to draw in fresh air from the indoor air outlet 14.

Problems to be Solved by the Invention In such a conventional configuration, when trying to take in a large amount of outside air, the amount of air flowing in from the opening 15 is induced by the operation of the indoor blower 12, so the amount of air supply is There are very few. That is, the indoor blower 12 pulls air from the opening 16 through the opening 16 by the indoor blower 12 to draw outside air flowing from the outdoor air intake lower toward the outdoor air outlet 1o through the outdoor air intake lower when the outdoor blower 9 is operated. Despite wanting to take in as much air as possible, only a small amount of outside air can be taken in. When a large amount of air supply is taken in, there is a problem in that the operation of the room conditioner must be stopped and only the indoor blower must be operated for ventilation.

The present invention is intended to solve such problems, and aims to obtain a sufficient amount of air supply with openings of the same size.

Means for Solving the Problem In order to solve this problem, the present invention includes a sleeve provided on a wall, and an outdoor unit part and an indoor unit part formed by a partition plate in the main body housed in the sleeve, An air supply ventilation path is formed between the sleeve and the outside of the main body from an outdoor intake port to a communication port opened in the outdoor unit part, and an opening is provided in the partition plate, and the communication port is connected to the communication port. A substantially box-shaped partition plate is provided corresponding to the opening of the partition plate, and a damper is provided to switch between opening and closing the opening side and the communication port side of the partition plate.

Function In this configuration, when the air conditioner is operated, outside air is drawn from the outdoor intake port by the indoor blower to the communication port through the air supply ventilation path formed between the sleeve and the main body, and is further inflowed from the opening. The substantially box-shaped partition plate allows sufficient outside air to be taken in regardless of the ventilation of the outdoor unit.

EXAMPLE Hereinafter, an example according to the present invention will be described based on FIG. In addition, the same reference numerals as explained in the conventional example indicate the same thing,
The explanation will be omitted. A main body 3 is housed inside a sleeve 2 fixed to a wall 1. Between this sleeve 2 and the outside of the main body 3, an air supply passage 19 is formed for the outside air to flow in from the outside air intake port 18 formed at the lower part of the outdoor intake lower. It communicates with the inside of the outdoor unit section 6 via a communication port 20 opened at the lower side.

A portion of the partition plate 4 that partitions the outdoor unit 6 and the indoor unit 6, near the communication port 20, has an indoor unit section 6.
An opening 15 is provided that communicates with the side, and this opening 16 is provided with a damper 16 that is open when outside air is taken in and closed when outside air intake is blocked, that is, when ventilation is not required. There is. At a position corresponding to the opening 16 and the communication port 20, a section is formed so as to cover the opening 15 and the communication port 2o and regardless of the ventilation inside the outdoor unit section 5. A box-shaped partition plate 21 is provided. That is, the partition plate 21 is formed in a shape corresponding to the communication port 20 and the opening 15.

In the above configuration, by operating the outdoor blower 9 and the indoor blower 12, on the outdoor unit section 6 side, outside air flows in from the outdoor intake lower, passes through the outdoor heat exchanger 8, and is blown by the outdoor blower 9 to the outdoor air outlet. 10 to the outside as shown by arrow A, and outside air flows in from outside air intake 18 as shown by arrow B, passing through air supply passage 19 to communication opening 20.
Since the damper 16 is open, when trying to take in outside air, the indoor air blower 12 draws the outside air from the opening 15 toward the indoor unit section 6 side.

At this time, the partition plate 21 allows air to flow in regardless of the air flow path (arrow A) inside the outdoor unit section 6. The induced air mixes with the air flowing in from the indoor air intake 11, is heated or cooled by the indoor heat exchanger 13, and is blown out into the room from the indoor air outlet 14 along with some fresh air and air conditioned. It is. Further, when outside air intake is not necessary, the opening 16 is closed by the damper 16. In this embodiment, the damper 16 that opens and closes the opening 16 is provided, but a damper that opens and closes the communication port 20 may also be provided.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides an air supply passage leading to the communication port provided in the outdoor unit portion of the main body between the sleeve and the outside of the main body, and the communication port and A damper is provided to switch open and close an opening in the partition plate that communicates with the indoor unit, and a substantially box-shaped partition plate is provided corresponding to the opening and the communication port, so that the air flow path in the outdoor unit is Regardless, since outside air is taken in through the air supply passage by an indoor blower, a sufficient amount of ventilation air can be obtained, there is no need to make the opening large, and ventilation can be carried out quickly. This has the effect that it is not necessary.
