The dust filter may be, for example, one having a mesh structure formed by weaving a thread-like PET material or one having a nonwoven fabric formed in a pleated shape.

  In addition, the radiation panel 4 is heated or cooled by heat conduction of the air heat exchanged with the refrigerant in the right heat exchanger 3a and the left heat exchanger 3b instead of the radiation due to the circulation of the refrigerant, so that the heat radiation is transmitted to the air-conditioned space. Or you may make it cool-radiate. At this time, instead of heat conduction by air, a heat conduction member formed of a material having good heat conductivity (for example, copper material or aluminum material) is used as the right heat exchanger 3a, the left heat exchanger 3b, and the radiation panel. 4 may be interposed. Or when the communication part 14 and the drain pan 15 are formed with the material with favorable heat conductivity, the radiation panel 4 is arrange | positioned so that these communication parts 14 and the drain pan 15 may be contacted, and the right side heat exchanger 3a and left side The heat conduction from the heat exchanger 3b to the radiation panel 4 may be performed via the communication portion 14 and the drain pan 15.

  When performing the cooling operation with the indoor unit 1 described above, the refrigerant cooled by the outdoor unit (not shown) flows into the right heat exchanger 3a, the left heat exchanger 3b, and the radiation panel 4. The air taken into the housing 10 through the suction port 2 by the rotation of the blower fan 2 and flowing through the right air flow path 20R and the left air flow path 20L is cooled by the refrigerant in the right heat exchanger 3a and the left heat exchanger 3b. Then, the air is blown into the air-conditioned space from both or one of the right air outlet 12a and the left air outlet 12b. Further, the air in the air-conditioned space is cooled by the cold radiation from the radiation panel 4.

  On the other hand, when the indoor unit 1 performs the heating operation, the refrigerant heated by the outdoor unit (not shown) flows into the right heat exchanger 3a, the left heat exchanger 3b, and the radiation panel 4. The air taken into the housing 10 from the suction port 2 by the rotation of the blower fan 2 and flowing through the right air flow path 20R and the left air flow path 20L is heated by the refrigerant in the right heat exchanger 3a and the left heat exchanger 3b. Then, the air is blown into the air-conditioned space from both or one of the right air outlet 12a and the left air outlet 12b. Further, the air in the air-conditioned space is warmed by the thermal radiation from the radiation panel 4.

  Next, when the indoor unit 1 performs the cooling operation or the heating operation, the air inside the housing 10 when the conditioned air is blown out from either the right outlet 12a or the left outlet 12b to the conditioned space. The operation of the communication part 14 will be described.

  First, the case where conditioned air is blown out only from the left outlet 12b will be described with reference to FIG. In this case, the right flap 13a is fully closed, and the left flap 13b is opened at an angle corresponding to the blowing direction desired by the user.

  The air that has flowed into the housing 10 from the suction port 11 by rotating the blower fan 2 at a rotational speed corresponding to the amount of blown air desired by the user is divided into the right air passage 20R and the left air passage 20L. The air flowing through the left air flow path 20L is heated or cooled by exchanging heat with the refrigerant in the left heat exchanger 3b, and blown out from the left outlet 12b to the conditioned space. That is, the conditioned air that flows into the left air flow path 20L from the suction port 11 and blows out from the left outlet 12b to the conditioned space flows like a left air flow WL1 shown in FIG.

  On the other hand, since the air flowing through the right air flow path 20R is heated or cooled by exchanging heat with the refrigerant in the right heat exchanger 3a, the right outlet 12a is fully closed by the right flap 13a. It flows downward of the body 10. And the air which flows below passes through the communication hole 14a of the communication part 14, flows in into the left air flow path 20L, and is blown out into the air-conditioned space from the left air outlet 12b. That is, the conditioned air that flows into the right air flow path 20R from the suction port 11 and blows out from the left outlet 12b to the conditioned space through the communication hole 14a is like the left auxiliary air flow WL2 shown in FIG. Flowing.

  As described above, when the conditioned air is blown out only from the left outlet 12b, the air that has exchanged heat with the refrigerant not only in the left heat exchanger 3b but also in the right heat exchanger 3a is passed through the communication hole 14a of the communication portion 14. Therefore, the amount of heat exchange is increased and energy saving is improved as compared with the case where only the left heat exchanger 3b is used.

  Next, the case where conditioned air is blown out only from the right outlet 12a will be described with reference to FIG. In this case, the left flap 13b is fully closed, and the right flap 13a is opened at an angle corresponding to the blowing direction desired by the user.

  The air that has flowed into the housing 10 from the suction port 11 by rotating the blower fan 2 at a rotational speed corresponding to the amount of blown air desired by the user is divided into the right air passage 20R and the left air passage 20L. The air flowing through the right air flow path 20R is heated or cooled by exchanging heat with the refrigerant in the right heat exchanger 3a, and blown out from the right outlet 12a to the conditioned space. That is, the conditioned air that flows into the right air flow path 20R from the suction port 11 and blows out from the right outlet 12a to the conditioned space flows like a right air flow WR1 shown in FIG.

  On the other hand, since the air flowing through the left air flow path 20L is heated or cooled by exchanging heat with the refrigerant in the left heat exchanger 3b, the left outlet 12b is fully closed by the left flap 13b. It flows downward of the body 10. And the air which flows below passes through the communicating hole 14a of the communicating part 14, flows into the right air flow path 20R, and is blown out from the right outlet 12a to the air-conditioned space. That is, the conditioned air that flows into the left air flow path 20L from the suction port 11 and blows out from the right outlet 12a to the conditioned space through the communication hole 14a is like a right auxiliary air flow WR2 shown in FIG. Flowing.

  As described above, when the conditioned air is blown out only from the right outlet 12a, the air that has exchanged heat with the refrigerant not only in the right heat exchanger 3a but also in the left heat exchanger 3b is passed through the communication hole 14a of the communication portion 14. Therefore, the amount of heat exchange is increased and energy saving is improved as compared with the case where only the right heat exchanger 3a is used.

  Next, a usage example in which conditioned air is blown out from one of the air outlets of the indoor unit 1 as described above will be described with reference to FIG. In FIG. 4, the case where the inner machine 1 of this invention is installed in the floor surface of the room 100 as an air-conditioned space which consists of the kitchen 100a and the living room 100b is shown. The kitchen 100a and the living room 100b are partitioned by a counter 200 except for a passage 100c that can travel between each other. Further, since the kitchen 100a is on the left side when the indoor unit 1 is viewed from the front side, the left flap 13b is opened and the right flap 13a is closed so that the conditioned air is blown out only from the left outlet 12b.

  The indoor unit 1 is installed so that the radiation panel 4 faces the living room 100b by arranging the back plate 10c along the wall surface of the room 100. When the indoor unit 1 installed in this way cools or heats the room 100, the living room 100b is cooled or heated by the radiation Rh from the radiation panel 4.

  On the other hand, for the kitchen 100a, the counter 200 prevents the radiation Rh. Accordingly, the kitchen 100a is cooled or heated by the left air flow WL1 and the left auxiliary air flow WL2 which are opened only from the left flap 13b and blown out from the left outlet 12b.

  At the start of the cooling operation or the heating operation, in addition to the radiation Rh by the radiation panel 4, the right side air flow WR1 and the right side auxiliary air flow WR2 shown in FIG. By blowing air, the temperature of the living room 100b may quickly reach the set temperature, and after reaching the set temperature, the cooling or heating of the living room 100b may be performed only by the radiation Rh by the radiation panel 4.

  As described above, the living room 100b can be cooled or heated without the draft feeling by the radiation Rh of the radiation panel 4, and the kitchen 100a that cannot be cooled or heated by the radiation Rh is based on the left air flow WL1 and the left auxiliary air flow WL2. Cooling or heating can be performed. Accordingly, two indoor spaces (kitchen 100a and living room 100b) can be simultaneously performed by one indoor unit 1.

  In the embodiment described above, the case where the right flap 13a and the left flap 13b are each formed of a single plate has been described. However, even if each of the right flap 13a and the left flap 13b is divided into a plurality of pieces in the vertical direction, Good. In this way, for example, by opening only the lower flap during heating operation, the warm air blown from each outlet can be blown out only to the feet, and only the upper flap during cooling operation. By opening, the blown cold air is not sent to your feet. Furthermore, when only one of the upper and lower flaps is opened as compared with the case where all the flaps are opened, the blowing speed is increased, and hot air or cold air can be delivered to the far side of the room.

  Further, the direction of the air blown from the right outlet 12a and the left outlet 12b between the right heat exchanger 3a and the right outlet 12a and between the left heat exchanger 3b and the left outlet 12b is set in the vertical direction. A sub-flap that deflects the light may be provided. By providing such a sub-flap, it is possible to perform finer wind direction control in combination with the movement of the right flap 13a and the left flap 13b.

  Next, a second embodiment of the air conditioner of the present invention will be described mainly using FIG. In the air conditioner according to the second embodiment of the present invention, the structure of the communication portion provided in the indoor unit and the operation of the communication portion when air is blown out from only one outlet are the air in the first embodiment. Since it is the same as a harmony machine, detailed description about the structure and operation | movement is abbreviate | omitted.

  As shown in FIG. 5, the indoor unit 1 a of the air conditioner in the present embodiment has a suction port 11 in the top plate 10 a as in the indoor unit 1 in the first embodiment, but the blower fan 2 is connected to the suction port 11. Is not arranged. The right side plate 10d and the left side plate 10e are provided with the rectangular right outlet 12a and left outlet 12b, the right flap 13a, and the left flap 13b provided in the indoor unit 1 of the first embodiment. Instead, the right side plate 10d is provided with a right side first outlet 12c and a right side second outlet 12d, and the left side plate 10e is provided with a left side first outlet. An air outlet 12e and a left second air outlet 12f are provided.

  Each of the right first air outlet 12c and the right second air outlet 12d is a circular through hole, and is arranged in the vertical direction on the right plate 10d. The right first blower fan 2a is disposed at the right first blower outlet 12c, and the right second blower fan 2b is disposed at the right second blower outlet 12d. Each of the right first blower fan 2a and the right second blower fan 2b is a propeller fan formed of, for example, a synthetic resin material, and is rotated by a motor (not shown). The right first blower fan 2a and the right second blower fan 2b are the first blower fan of the present invention. In addition, the shape of each blower outlet is not restricted to circular shape, The through-hole of other shapes, such as square shape and ellipse shape, may be sufficient.

  Each of the left first air outlet 12e and the left second air outlet 12f is a circular through hole, and is arranged in the vertical direction on the left side plate 10e. A left first blower fan 2c is disposed at the left first blower outlet 12e, and a left second blower fan 2d is disposed at the left second blower outlet 12f. Each of the left first blower fan 2c and the left second blower fan 2d is a propeller fan formed of, for example, a synthetic resin material, and is rotated by a motor (not shown). The left first blower fan 2c and the left second blower fan 2d are the second blower fans of the present invention.

  When performing the cooling operation or the heating operation with the indoor unit 1a described above, when the conditioned air is blown out only from the left first outlet 12e and the left second outlet 12f, the left first blower fan 2c and the left second fan While rotating the fan 2d, the right first blower fan 2a and the right second blower fan 2b are stopped. The air taken into the housing 10 from the suction port 11 by the rotation of the left first blower fan 2c and the left second blower fan 2d is the right air flow path and the left side as in the indoor unit 1 in the first embodiment. Shunt into the air flow path.

  The air flowing through the left air flow path is heated or cooled by exchanging heat with the refrigerant in the left heat exchanger 3b, and blown out from the left first air outlet 12e and the left second air outlet 12f to the conditioned space. On the other hand, since the air flowing through the right air flow path is heated or cooled by exchanging heat with the refrigerant in the right heat exchanger 3a, the right first blower fan 2a and the right second blower fan 2b are stopped. Then, it flows toward the bottom of the housing 10. The conditioned air flowing downward passes through the communication hole 14a of the communication portion 14, flows into the left air flow path, and is blown out into the conditioned space from the left first air outlet 12e and the left second air outlet 12f.

  When air is blown out only from the right first blower outlet 12c and the right second blower outlet 12d, the right first blower fan 2a and the right second blower fan 2b are rotated, and the left first blower fan 2c and the left first blower fan 2c are rotated. The 2 blower fan 2d is stopped. The air taken into the housing 10 from the suction port 11 by the rotation of the right first blower fan 2a and the right second blower fan 2b is the right air flow path and the left side as in the indoor unit 1 in the first embodiment. Shunt into the air flow path.

  The air flowing through the right air flow path is heated or cooled by exchanging heat with the refrigerant in the right heat exchanger 3a, and blown out from the right first air outlet 12c and the right second air outlet 12d to the conditioned space. On the other hand, since the air flowing in the left air flow path is heated or cooled by exchanging heat with the refrigerant in the left heat exchanger 3b, the left first blower fan 2c and the left second blower fan 2d are stopped. Then, it flows toward the bottom of the housing 10. The conditioned air flowing downward passes through the communication hole 14a of the communication portion 14, flows into the right air flow path, and is blown out from the right first air outlet 12c and the right second air outlet 12d to the conditioned space.

  As described above, when conditioned air is blown out from only one of the left and right outlets, only the blower fan provided at the outlet is rotated, and the refrigerant and heat are heated in the heat exchanger on the side opposite to the blower fan to be rotated. Since the conditioned air that has been exchanged can be blown out from the outlet through the communication hole 14a of the communication portion 14, the amount of heat exchange increases compared to the case where only one of the heat exchangers is used, thus saving energy. Will improve. In addition, in the indoor unit 1a of this embodiment, although the case where the flap demonstrated in 1st Embodiment was not provided in each blower outlet was demonstrated, if a flap is provided in each blower outlet in this embodiment, it will become finer. Wind direction control can be performed.

  In each of the embodiments described above, the air outlets are provided in the right side plate and the left side plate, that is, the indoor unit in which two air outlets are provided in the casing is described as an example, but the present invention is not limited thereto. An indoor unit in which three or more outlets are provided in the housing may be used. In addition, the communication part provided in the indoor unit having three or more air outlets flows through an air flow path connected to the air outlet that does not blow out air when there are air outlets that blow out air and air outlets that do not blow out air. What is necessary is just to make it the shape which guides the air after heat exchange to the air flow path connected to the blower outlet which blows off air-conditioning air.

  Moreover, although the case where the heat exchanger is arranged in a V shape in each embodiment has been described, the present invention is not limited to this, and the heat exchanger is arranged in an inverted V shape or in a W shape. May be. In addition, when arrange | positioning a heat exchanger in W shape, two drain pans are arrange | positioned corresponding to the bottom part of two places of W shape.
