  Such an air conditioner, for example, allows outside air to flow as supply air through one of the first ventilation air passage and the second ventilation air passage, and supplies the air to the air-conditioning target space. The air in the air-conditioning target space is made to flow as exhaust air through the passage and is discharged to the outside, and heat exchange is performed between the air for supply and the air for exhaust in the heat exchanger. For example, it is used in an application in which a plurality of rooms in a house are air-conditioned spaces, and is installed on the ceiling of a house.

  In other words, air in an air-conditioning target space or indoor air sucked from another space such as a corridor is used as the exhaust air, and one internal passage in the heat exchanger, the heating means in a heating operation state, and the humidity control Passing through the first ventilation air passage so as to pass through a partial region of the body and exhaust to the outside, and using the outside air as the supply air, the other region of the humidity control body, the heat exchanger When the air is passed through the second ventilation air passage so as to pass through the other internal passage and be supplied to the air-conditioning target space, the exhaust air from the air-conditioning target space is heated by the heating means and then the humidity control body In the supply air by operating in such a manner that it passes through a part of the area and is discharged to the outside and the outside air passes through another area of the humidity control body and is supplied to the air-conditioning target space.

  In the above-described conventional configuration, the heat exchanger and the humidity control rotor are arranged in a separated state in the casing, so that the heat exchanger and the humidity control rotor of the casing are arranged. Since the size of the installation space in the direction becomes large, as a result, the size of the casing in the arrangement direction becomes large, which disadvantageously increases the size of the entire apparatus. As a result, for example, when installing in a narrow space such as a ceiling of a house, there is a disadvantage that the apparatus becomes large and difficult to handle in installation work.

  An object of the present invention is to provide an air conditioner that can be downsized to facilitate installation work and the like.

An air conditioner according to the present invention is a heat exchanger that exchanges heat while allowing air to flow through two internal passages that are formed in a casing and formed across a pair of two sides facing each other so as to cross each other. And a humidity control rotor that is provided so as to allow air to pass therethrough and that adjusts the humidity of the passing air and a drive means for driving and rotating the humidity control body, the four corners of the heat exchanger. Are arranged in a state in which one of the corners is arranged in an oblique posture toward the humidity control rotor,
A partial region of the humidity control body, one end side entrance / exit part of one internal passage in the heat exchanger, and a first ventilation air passage through which air flows through the one internal passage, and Other areas excluding a partial area of the humidity control body, one end side entrance / exit part of the other internal passage in the heat exchanger, and a second ventilation air passage through which air flows through the other internal passage are formed. In the form, the inside of the casing is partitioned,
A heating means for heating the air flowing through the first ventilation air passage is provided in the first ventilation air passage,
The humidity control rotor is disposed so that the partial area of the humidity control body is located in the first ventilation air passage and the other area is located in the second ventilation air passage, and Arrangement of the heat exchanger and the humidity control rotor by the driving means so that the portion located in the first ventilation air passage and the portion located in the second ventilation air passage in the wet body change with rotation. It is configured to be rotated around an axis along the direction,
The first characteristic configuration is the state in which the one corner of the heat exchanger is brought close to the humidity control rotor, and the heat exchanger and the humidity control rotor are arranged close to each other ,
The first ventilation air passage is configured to flow air from the heat exchanger toward the humidity control rotor;
In the heat exchanger, a side surface on the humidity control rotor side forming an inlet / outlet portion of one end of the one internal passage forming the first ventilation air passage is arranged in an arrangement direction of the heat exchanger and the humidity control rotor Is deployed in a state of being inclined at an angle greater than 45 degrees with respect to a virtual line along
In the heat exchanger, the second ventilation air is provided at one corner portion of the second ventilation air more than the rotational axis of the humidity control rotor along a direction orthogonal to an arrangement direction of the heat exchanger and the humidity control rotor. It is in a point where it is deployed in a state where it is located at a location close to the roadside .

  According to the first feature configuration, in the casing, the heat exchanger and the humidity control rotor are arranged close to each other in a state where the one corner portion of the heat exchanger is brought close to the humidity control rotor. The installation space in the arrangement direction of the heat exchanger and the humidity control rotor can be shortened, the dimensions of the casing in the arrangement direction can be reduced, and the entire apparatus can be reduced in size. It becomes.

  Therefore, according to the 1st characteristic structure, it came to be able to provide the air conditioner which can be reduced in size and can make installation work etc. easy.

According to the first characteristic configuration, in the casing, the heat exchanger is set to the humidity control rotor, and one corner portion of the four corner portions of the heat exchanger is set to the humidity control rotor. In deployment in a state of being lined up in an inclined posture, the side surface on the humidity control rotor side that forms the one-side inlet / outlet portion of the one internal passage that forms the first ventilation air passage is connected to the heat exchanger and the conditioning device. Since it is arranged in a state where it is inclined at an angle larger than 45 degrees with respect to a virtual line along the direction of alignment with the wet rotor, the air flowing so as to pass through the first ventilation air passage is heated. When discharged from the other end side of the one internal passage in the exchanger and flows toward the humidity control rotor, it is possible to appropriately flow to a location near the rotational axis of the humidity control rotor. , Located in the first ventilation air passage in the humidity control rotor It is possible to flow the air substantially uniformly to the portion that.

In other words, when the heat exchanger and the humidity control rotor are arranged close to each other, the side surface on the humidity control rotor side forming the one end side entrance / exit portion of the one internal passage in the heat exchanger is the heat One end of the one internal passage in the heat exchanger if it is arranged in a state where it is inclined at an angle of 45 degrees or close to an imaginary line along the alignment direction of the exchanger and the humidity control rotor Since the air discharged from the side inlet / outlet portion flows to the humidity control rotor with an inclination of 45 degrees or an angle close thereto, for example, when passing through the humidity adjustment rotor, the humidity adjustment rotor has an inclination angle of 45 degrees Therefore, there is a disadvantage that it is difficult to flow in the humidity control rotor. As a result, there is a possibility that the humidity control action such as dehumidification and humidification on the air by the humidity control rotor cannot be performed satisfactorily. On the other hand, according to the first characteristic configuration, the side surface on the humidity control rotor side forming the one end side entrance / exit portion of the one internal passage forming the first ventilation air passage is formed by the heat exchanger and the Since it is deployed in a state where it is inclined at an angle greater than 45 degrees with respect to the imaginary line along the direction of alignment with the humidity control rotor, air is supplied to the humidity control rotor as much as possible along the rotation axis direction. By supplying the air, it is possible to ventilate the air in a state where it can easily flow.

Therefore, according to the first characteristic configuration, it is possible to ventilate the air in a state in which air easily flows to the humidity control rotor, and the humidity control operation such as dehumidification and humidification with respect to the air by the humidity control rotor is favorably performed. It becomes possible.

It becomes possible to make the flow more equal.

Therefore, according to the first characteristic configuration, the flow of air to the humidity control rotor can be made more uniform, and the humidity control operation such as dehumidification and humidification of the air by the humidity control rotor can be performed better. Become.

According to the second characteristic configuration, the heating means for heating the air flowing through the first ventilation air passage is on the humidity control rotor side forming the one end side entrance / exit portion of the one internal passage in the heat exchanger. Since it is provided in a state of being close to each other along the side surface, the air that has passed through one internal passage of the heat exchanger will be subjected to a heating action almost uniformly with no unevenness. The temperature is supplied to the humidity control rotor in a uniform state with little variation.

  Therefore, the air temperature after being heated by the heating means can be supplied to the humidity control rotor in a uniform state with little variation, and the heat exchange is performed by efficiently evaporating the moisture of the humidity control rotor. It is possible to increase the humidity control performance when humidifying the air passing through the one internal passage of the oven or dehumidifying the air passing through the other internal passage of the heat exchanger. Further, the area through which air passes can be increased, and the pressure loss can be reduced.

The third characteristic configuration of the present invention, in addition to the first characterizing feature and the second feature configuration, ventilation a first ventilating means for ventilating air through the first vent air passage, the air through the second vent air passage A second ventilation means for allowing the humidity control rotor and the heat exchanger to be arranged in the casing with respect to an air conditioner installation space in which the humidity control rotor and the heat exchanger are provided.

Will be. Then, the air that is ventilated by the ventilating action of the first ventilating means and the air that is ventilated by the ventilating action of the second ventilating means are heat-exchanged by the heat exchanger and are subjected to the humidity adjusting action by the humidity adjusting rotor.

  For example, air in the air-conditioning target space is sucked from the inlet of the first ventilation air passage and exhausted to the outside, and outside air is sucked from the inlet of the second ventilation air passage and supplied to the air-conditioning target space. Ventilation makes it possible to ventilate the air-conditioned space while dehumidifying it. In addition, outside air is sucked from the inlet of the first ventilation air passage to supply air into the air-conditioning target space, and air in the air conditioning target space is sucked from the inlet of the second ventilation air passage and exhausted to the outside. By ventilating, it becomes possible to ventilate the air-conditioned space while humidifying it.
