Abstract

PURPOSE:To enable inlet ports, provided in a pair adjacently to the casing, to be placed nearer to each other by providing a heat exchanger in which its side on the side of the circulation space leans at a specified angle with respect to the top side of the casing, with the rotation axis of the switching damper perpendicularly meeting the side on the side of the circulation space, and close and parallel to a partition plate on the side of the circulation space. CONSTITUTION:Relating to a heat exchanger 1, the side on the side of the circulation space 1c forms an angle of 45 deg. to 90 deg. with the top side Vc3 of the casing Vc and the rotation axis Da of the switching damper D meets the side on the side of the circulation space 1c perpendicularly. As a result, the path of a rotated switching damper does not project into the circulation space from a plane extending from the side on the side of the circulation space. Furthermore, a partition plate 6s on the side of the circulation space is tilted close and parallel to the side on the side of the circulation space 1c. As a result, the inlet port 10 on the circulation side can be placed closer to the inlet port 6a on the exhaust side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to air for supplying air from the outside and exhausting air from the room to a heat exchanger for ventilation while exchanging heat, and for air cleaning while circulating the air in the room. It relates to a harmony device.

[0002]

2. Description of the Related Art Conventionally, in order to reduce energy for air conditioning and to perform comfortable air conditioning, heat is exchanged between the air supply from the outside to the room and the exhaust from the room to the outside. There was an air conditioner that ventilated while letting it go. In the above air conditioner, in order to remove dust and the like contained in the indoor air, an indoor air circulation duct for circulating the indoor air through a filter or the like is provided, and further, this indoor air is exhausted and returned. There was something to distribute to. But,
In this air conditioner, since the dispersed devices are connected by ducts, there is a problem that the air conditioner body becomes large.

[0003]

Therefore, it is conceivable to incorporate each device into a unitary casing or a plurality of casings connected to each other to form a unit. However, in the air conditioner of the above-mentioned integrated type or the like, the air supply side air passage, the exhaust side air passage, and the indoor air circulation air passage are arranged inside the casing, and each side surface of the casing has A suction port and a blowout port to the air passage will be arranged. Due to the layout, the exhaust side suction port (suction port to the exhaust side air passage) and the circulation side suction port (suction to and opening to the circulation side air passage) must be placed close to each other on one side of the casing. It may not be.

On the other hand, in order to switch between total heat exchange ventilation for exchanging heat between the supply air and exhaust air and ordinary ventilation for ventilation without heat exchange, the exhaust side air passage passes the indoor air through the heat exchanger. There are two parts that are divided into an air passage for exhausting the air and a bypass air passage for bypassing the heat exchanger. In such an air conditioner, switching between the two air passages is
This is done by a switching damper arranged in the air passage switching space.

However, this air passage switching space is arranged between the above-mentioned exhaust side suction port and the accommodation space of the heat exchanger, and due to the layout, the heat exchanger having a quadrangular prismatic cross section. In some cases, the air passage switching space and the exhaust side suction port are arranged on the back side in the longitudinal direction along the longitudinal direction. In this case, the arrangement interval between the exhaust side intake port and the circulation side intake port, which is arranged on one side surface of the casing, is defined by the size of the space required for the air passage switching space. Had the problem of becoming larger. Therefore, the object of the present invention is to
By solving the above-mentioned technical problem, it is possible to realize an air conditioner capable of reducing the size between a pair of suction ports arranged adjacent to one side surface of a casing and achieving miniaturization.

[0006]

In order to achieve the above object, an air conditioner according to a first aspect of the present invention is such that the longitudinal direction is orthogonal to the blowing direction of the air supply side air passage that penetrates through the casing. , A long heat exchanger arranged in a heat exchanger accommodating space in a casing and having a substantially rectangular prismatic cross section for heat exchange between air supply from the outside and exhaust air from the room, and the length of the heat exchanger. Along the end face in the direction, the air passage switching space partitioned between the heat exchanger housing space side partition plate and one side surface of the casing facing the heat exchanger accommodation space side, and the air passage switching space disposed in the air passage switching space. One side of the casing and a switching damper that switches the indoor air sucked from the exhaust side intake port formed on the side surface to the exhaust side main air passage that passes through the heat exchanger and the bypass air passage that bypasses the heat exchanger. The above exhaust A circulation side suction port having a round cross section, which is provided in the vicinity of the suction port and is introduced into the circulation space partitioned through the air passage switching space and the circulation space side partition plate in order to circulate the air in the room. In the air conditioner provided, the heat exchanger is inclined such that the side surface of the heat exchanger on the side of the circulation space forms a predetermined angle larger than 45 ° and smaller than 90 ° with the upper surface of the casing. The rotation axis of the damper is arranged so as to be substantially orthogonal to the side surface of the heat exchanger on the side of the circulation space, and the partition plate on the side of the circulation space is inclined so as to extend substantially along the side surface of the heat exchanger on the side of the circulation space. It is characterized by being.

[0007]

In a normal heat exchanger in which the side surface on the side of the circulation space makes an angle of 45 ° with the upper surface of the casing, the ridgeline of the heat exchanger, which is the lower edge of the side surface on the side of the circulation space, is closest to the side of the circulation space. It was outstanding. On the other hand, according to the present invention, since the heat exchanger is inclined more than usual, it is possible to bring the ridgeline of the heat exchanger, which projects the most toward the circulation space side, closer to the bottom surface side of the casing.

Therefore, the circulation side suction port having a round cross section is connected to the exhaust side suction port side so as to be substantially in contact with the circulation space side partition plate which is slanted so as to substantially follow the slanted circulation space side surface. It is possible to arrange them closer. Thereby, the air conditioner can be made smaller. Since the rotation axis of the switching damper arranged in the air passage switching space is orthogonal to the side surface on the side of the circulation space, the trajectory of the rotation of the switching damper is from the extension surface of the side surface on the side of the circulation space to the circulation space. Does not project to the side.
Therefore, even if the circulation space side partition plate is inclined along the side surface of the circulation space side, the circulation space side partition plate does not interfere with the switching damper.

It is partitioned via s. With reference to FIG. 1, the heat exchanger 1 causes heat exchange between the two air streams of the supply air and the exhaust air, which are input to the first side surface 1a and the second side surface 1b, respectively.

Further, since the rotation axis Da of the switching damper D arranged in the air passage switching space 6 is made orthogonal to the circulation space side surface 1c, the locus of rotation of the switching damper D is the circulation space side. From the extension of the side surface 1c, the circulation space 1
It does not project to the 0 side. Therefore, even if the circulation space side partition plate 6s is inclined along the circulation space side surface 1c, the circulation space side partition plate 6s does not interfere with the switching damper D.
