Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat pump type individual air conditioner installed in a perimeter zone of a building or the like.

Conventional configurations and their problems Traditionally, individual heat pump air conditioners are installed in the perimeter zone of buildings, etc., but these individual air conditioners require a portion of outside air to be introduced during heating and cooling. On the other hand, there are some that are equipped with an intake/exhaust device that also exhausts a portion of the indoor air. When this intake/exhaust device performs intake/exhaust, it is preferable that a total heat exchanger is used to recover exhaust heat while exhausting indoor air-conditioned air.

An example of using such a total heat exchanger is the one described in Japanese Patent Publication No. 19991/1983, for example.

The technology described in this publication takes in outside air from below the outside air intake hole installed in the wall and passes it through a total heat exchanger, and also crosses indoor air through the total heat exchanger to exchange heat with the outside air. is used to recover waste heat,
The air that has recovered exhaust heat is blown into the room through the air conditioner itself.

However, although the technology described in Japanese Patent Publication No. 47-19991 has the advantage of reusing the heat-recovered air in the air conditioner itself, the air on the exhaust side passes through the total heat exchanger and becomes the outside air. Therefore, the exhaust heat recovery effect is not sufficient.

In addition, the outside air intake installed on the wall must match the box of the air conditioner, or conversely, the outside air intake must match the box, and one or the other is regulated. With the diversification of architectural designs and air conditioner designs in recent years, the above-mentioned air conditioners have had the disadvantage of not being able to adequately respond to these demands.

Purpose of the Invention The present invention takes into consideration the above-mentioned conventional drawbacks and effectively recovers waste heat when exhausting air-conditioned indoor air in a heat pump type individual air conditioner installed in a perimeter zone or the like. It is an object of the present invention to provide a total heat exchanger that can accommodate any intake/exhaust openings provided in an outer wall.

Structure of the Invention In order to achieve the above-mentioned object, the present invention configures a heat pump type individual air conditioner separately from an outdoor unit, an indoor unit, and a total heat exchanger, and heats exhaust air from indoor air by the total heat exchanger. The heat exchanger includes a means for recovering and further reusing the outdoor air in an outdoor heat exchanger of the outdoor unit via a chamber, and a means for sucking in outside air through the heat exchanger via the chamber, and the heat exchanger has a An indoor exhaust port, a switching opening for intake and exhaust in the center of the rear panel, a duct placed in a rhombus shape with respect to the switching opening and having ventilation passages formed alternately, and the same ridgeline as this duct. Between the total heat exchanger placed above, the upper ridgeline of this duct and total heat exchanger, and the top plate, there is a left side that is on one side of the duct and total heat exchanger, similar to the first partition plate. The ridgeline and

A seventh partition plate is provided between the partition plate and the back panel and configures ventilation on one side of the duct, and an eighth partition plate also configures ventilation on the other side of the duct, and is configured in the switching opening. Through the chamber unit interposed between the exterior wall of the building and each unit using a plurality of intake ports and exhaust ports, it is possible to correspond to any opening in the exterior wall of the building and to exchange the total heat. In this system, indoor exhaust heat is recovered through a heat exchanger, communicated with the outdoor unit, and then utilized through an outdoor heat exchanger.

A first intake port 56 and a second intake port 57 are formed at a diagonal position thereof, and a first exhaust port 58 and a second exhaust port 59 are formed at a diagonal position thereof. . 60 is a shielding plate that connects the first intake port 56;
and the first exhaust port 58, the first exhaust port 58 and the second intake port 57, the second exhaust port 59 and the second intake port 57, and the first intake port 56 and the second intake port 57. 2
The exhaust port 59 can be used depending on the opening 6 of the chamber 4.

The above configuration will be explained using an example as shown in FIG. 1, in which the opening 3 of the outer wall 1 is provided in the waist wall. A chamber 4 is provided in contact with the opening 3. Next, the indoor unit 17 is installed on the right side of the chamber 4. The first exhaust port 58 of the switching opening 55 of the back panel 54 of the total heat exchanger 19 and the second
The intake port 57 is shielded by a shielding plate 60. This shielded total heat exchanger 19 is connected to the first intake port 56 and the chamber intake port 8, and then the second exhaust port 59
and the chamber exhaust port 9 and install them together. Next, align the outdoor air outlet 25 of the outdoor unit 18 with the main exhaust port 11, and then align the outdoor air intake port 27 with the main air intake port 10.
and install the outdoor unit 18.

Here, air is supplied to the indoor unit 17 through the suction port 20
Indoor air is sucked in, passes through an indoor blower 22 and an indoor heat exchanger 23, and is blown into the room from an outlet 21 for cooling and heating.

In the outdoor unit 18, approximately 90% of the outside air taken in from the outside air intake port 3a passes through the intake opening 13 of the chamber 4, the lower part of the partition plate 7 (dotted line arrow A), the main intake port 10, outdoor air intake port 27 of outdoor unit 18, outdoor heat exchanger 26, outdoor blower 24,
outdoor air outlet 25, main exhaust port 11 of chamber 4,
The air is discharged to the outside through the exhaust opening 12 and the outdoor exhaust port 3b of the outer wall 1.

Next, in the total heat exchanger 19, a part of the air-conditioned air is exhausted through the total heat exchanger 19, and a part of the outside air is introduced, and the indoor air is exhausted by the total heat exchanger 33. The heat is recovered into the outside air and blown into the room, and the exhausted indoor air is further ventilated through the outdoor heat exchanger 26, and the heat that cannot be completely recovered here is reused for double effect.

In other words, in the air flow path, a part of the indoor air flows in from the indoor exhaust port 29, flows as shown by the dotted arrow B (FIG. 3), flows diagonally through the total heat exchanger 33, passes through the exhaust blower 46, and then flows into the duct B39. Flows diagonally downward, and the second
It flows to the exhaust port 59, the chamber exhaust port 9, joins with the outside air shown by the dotted line arrow A, and flows to the main intake port 10, the outdoor air intake port 27 of the outdoor unit 18, and the outdoor heat exchanger 26, where it flows to the total heat exchanger. The conditioned air that was not completely recovered in step 33 is reused and is discharged to the outside through the outdoor outlet 25 of the outdoor blower 24, the exhaust opening 12, and the outdoor outlet 3b.

On the other hand, approximately 90% of the air flowing in from the outside air intake port 3a flows into the chamber 4 below the partition plate 7 as shown by the dotted line A in Figure 1, but about 10% of the outside air
It flows into the total heat exchanger 19 from the upper chamber intake port 8 of the partition plate 7, and flows into the total heat exchanger 19 through the first intake port 56 and the duct A38.
flows diagonally downward, flows between the second partition plate 42 and third partition plate 44, and flows diagonally upward through the total heat exchanger 33 (here heat exchanged with indoor air) in the intake air blower 53.
The air is blown into the room from the indoor air outlet 31.

The air flow path described above is obtained when the first exhaust port 58 and the second intake port 57 of the switching opening 55 are closed with the shielding plate 60, and then the opening 3 of the outer wall 1 is located below the waist wall. In the case of a building provided in the opening 3
A main air intake port 10 on the chamber side that is matched with the outdoor air intake port 27 of the outdoor unit 18 and the outdoor air outlet 25 is manufactured by manufacturing a chamber 4 that has a configuration that matches the chamber 4 and a partition plate that matches the opening 3 of the chamber 4. and a main exhaust port 11, while an opening 6 having a chamber intake port 8 partitioned by a partition plate 7 and a chamber exhaust port 9 is provided. However, since this opening 6 corresponds to the switching opening 55 of the total heat exchanger 19, the manner in which the shielding plate 60 is closed, in other words, the first intake port 56, the second intake port 57, and the first Depending on the openings of the exhaust port 58 and the second exhaust port 59, the opening 6 must be made into a horizontal rectangular shape.

For example, the first intake port 56 may be
It is assumed that the first exhaust port 58 is closed and the second intake port 57 and second exhaust port 59 are opened.

Then, a part of the indoor air flows into the flow path inside the total heat exchanger 19 from the indoor exhaust port 29, goes around below the fifth partition plate 47 as indicated by the dotted arrow B, and moves the total heat exchanger 33 diagonally upward. The air flows to the duct 40 side by the exhaust blower 46, flows obliquely downward through the duct B39, and is exhausted through the second exhaust port 59 and the chamber exhaust port on the chamber 4 side. On the other hand, when outside air flows in through the second air intake port 57, it flows below the second partition plate 42 and flows obliquely upward through the total heat exchanger 33.
At this time, the air seems to flow through the duct A38, but since the first air intake port 56 is closed, the ventilation becomes a dead end. Therefore, the air that has flowed diagonally upward through the total heat exchanger 33 is blown out into the room from the indoor air outlet 31 by the intake blower 53, and the air whose heat has been recovered in the total heat exchanger 33 is blown out. Become.

Next, a case where the first intake port 56 and the second exhaust port 59 are closed with the shielding plate 60 will be described.

A part of the indoor air flows in from the indoor exhaust port 29, flows below the fifth partition plate 47 as shown by the dotted arrow B, and flows obliquely upward through the total heat exchanger 33 to the exhaust blower 4.
6, the air is exhausted from the first exhaust port 58.
(Does not pass through either duct A38 or duct B39.) On the other hand, when outside air flows in through the second intake port 57, it flows below the second partition plate 42 and into the total heat exchanger 3.
3 flows diagonally upward, recovers heat, and passes through the intake blower 5.
3, the air is blown into the room from the indoor air outlet 31.

Next, a case where the second intake port 57 and the second exhaust port 59 are used with the shielding plate 60 closed will be described.

A part of the indoor air flows in from the indoor exhaust port 29, flows below the fifth partition plate 47 as shown by the dotted arrow B, and flows diagonally upward through the total heat exchanger 33, and then flows through the exhaust blower 4.
6, the air is exhausted from the first exhaust port 58. On the other hand, when outside air flows in through the first intake port 56, it flows obliquely downward through the duct A38, and the air flows through the second partition plate 42.
and the third partition plate 44, and the total heat exchanger 3
3 and is blown out into the room from the indoor air outlet 31 by the intake blower 53.

In this way, in the total heat exchanger 19, the shielding plate 60
By opening and closing the switching opening 55 in various ways, intake and exhaust flow paths are configured, and if the chamber 4 is provided with a partition plate corresponding to these openings and closings, the outer wall 1 can be Waist wall opening 3
However, it is possible to accommodate any shape of the opening, and the total heat exchanger 19 does not necessarily have to be placed in the center; it can also be installed at the left or right end. can. Furthermore, the air from which a part of the room is exhausted must pass through the total heat exchanger 33 for primary heat recovery, and also pass through the outdoor heat exchanger 26 of the outdoor unit 18 for secondary heat recovery. In other words, it is used for secondary purposes and then exhausted.

Effects of the Invention As is clear from the description of the above embodiments, the present invention provides a heat pump type individual air conditioner with an outdoor unit,
An indoor unit and a total heat exchanger are each configured separately, and the total heat exchanger has an indoor exhaust port below the front panel;
There is a switching opening for intake and exhaust in the center of the back panel,
A duct placed in a diamond shape with respect to this switching opening and having ventilation passages formed alternately, a total heat exchanger placed on the same ridgeline as this duct, and a total heat exchanger between this duct and the total heat exchanger. The above-mentioned first to ninth partition plates are provided between the upper and lower and left and right ridgelines, the duct and the total heat exchanger, and a shielding plate that allows air to be taken in and exhausted from the switching opening, and the shielding plate is connected to the chamber opening. By arbitrarily using it opposite the wall, it is a means to exhaust part of the indoor air and take in part of the outside air, so no matter what kind of opening there is in the outside wall. This is possible if the chamber has an opening corresponding to the switching opening, a main intake port, and a main exhaust port. Furthermore, some of the conditioned air that is exhausted from the indoor air must go through a total heat exchanger, where primary heat recovery is performed by the outside air, and any heat that cannot be recovered must go through an outdoor heat exchanger. With secondary heat recovery, i.e. can be reused,
This exhibits effects such as being able to increase effects from an energy saving standpoint.
