  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a schematic diagram showing a heat exchange device according to Embodiment 1 of the present invention. As shown in FIG. 1, the heat exchange air device 1 includes a housing 27, a heat exchange element 2 provided inside the housing 27, an air supply blower 3, an exhaust air blower 4, and a control unit 6. . The supply air blower 3 takes outside air A, which is outdoor air, into the room. The exhaust blower 4 discharges indoor air B, which is indoor air, to the outside. The heat exchange element 2 exchanges heat and moisture between the room air B and the outside air A.

  The housing 27 includes an outside air inlet 14, an indoor air inlet 15, an indoor inlet 7, and an exhaust 16. Here, the outside air A is sucked in from the outside air inlet 14 and supplied into the room from the indoor air inlet 15. The room air B is sucked from the indoor suction port 7 and discharged from the exhaust port 16 to the outside. The outside air A passes through a supply air passage 28 from the outside air inlet 14 to the indoor inlet 15. Further, the indoor air B passes through the exhaust air passage 29 from the indoor suction port 7 to the exhaust port 16. As described above, the supply air passage 28 and the exhaust air passage 29 are formed inside the casing 27.

  Between the outside air inlet 14 and the heat exchange element 2, an outdoor-side air purification filter 5 that purifies the outside air A is provided. A pre-filter 17 that protects the heat exchange element 2 from dirt is provided between the indoor suction port 7 and the heat exchange element 2.

  As shown in FIG. 1, in the heat exchange device 1, a cylindrical air conditioning member 40 a is attached to a duct 41 connected to the indoor suction port 7. An air conditioning member 40 b is attached to the outside air inlet 14. The dust sensor housings 20 of the dust sensor 8a and the dust sensor 8b are respectively attached to the air conditioning members 40a and 40b so that the inlet hole 24 is below the outlet hole 25.

  As shown in FIGS. 2 and 3, the air-conditioning member 40 (air-conditioning members 40 a and 40 b) has a cylindrical shape and is fitted to the duct 41 and the adapter of the outside air inlet 14 shown in FIG. 1.

  As shown in FIG. 2, the air conditioning member 40 includes a cylindrical member main body 42 and a box-shaped case 43. There is a through hole in the side wall of the cylindrical member main body 42 that leads to the box-shaped case 43. This through hole is partitioned by the shutter 44. The shutter 44 is configured by connecting the rotating shaft of the shutter 44 and the shaft of the stepping motor 46. Then, the shutter 44 is opened and closed by controlling the rotation direction of the stepping motor 46.

  In the box-shaped case 43, there is provided a dust sensor 8 including the light receiving unit 21, the light emitting unit 22, and the heating resistor 26 shown in FIG. As shown in FIG. 4, the dust sensor housing 20 of the dust sensors 8 a and 8 b has an inlet hole 24 for introducing air and an outlet hole 25. The air that has passed through the inlet hole 24 is discharged from the outlet hole 25 due to the rising airflow generated by the heat generation resistor 26 in the dust sensor housing 20. While the air that has passed through the inlet hole 24 rises from the inlet hole 24 to the outlet hole 25, the dust 23 reflects the infrared rays from the light emitting unit 22, receives the signal at the light receiving unit 21, and determines the amount of suspended particles and the suspended particle diameter. Determine.

  As shown in FIGS. 2 and 3, the dust sensor 8 is installed in parallel to the cylindrical direction of the member main body 42, that is, the central axis direction of the cylinder. As a result, the wind direction passing through the member main body 42 intersects the air flow direction from the inlet hole 24 toward the outlet hole 25. Therefore, the air flow in the vicinity of the inlet hole 24 in the dust sensor housing 20 is not easily affected by the wind speed passing through the member main body 42. That is, the air velocity passing through the outlet hole 25 from the inlet hole 24 is only an ascending airflow at a constant speed due to the heat generated by the heating resistor 26 in FIG. 2, so that stable suspended particles can be determined.

  2 and 3, since the air conditioning member 40 has a cylindrical shape, it can be connected to the duct 41 of FIG. 1 so that the inlet hole 24 is below the outlet hole 25. Moreover, it can attach to the external air inlet 14 and the adapter of the indoor inlet 7 so that the inlet hole 24 may become below the outlet hole 25. FIG. As shown in FIG. 4, the inlet hole 24 and the outlet hole 25 are arranged on the opposing surfaces of the dust sensor housing 20. The surface on which the inlet hole 24 and the outlet hole 25 are installed is attached so as to be parallel or orthogonal to the cylindrical direction of the air conditioning member 40. Therefore, depending on the mounting direction of the air conditioning member 40, the connection can be made so that the inlet hole 24 is below the outlet hole 25.

  That is, the main body of the heat exchange device 1 needs to be installed upside down or on the wall depending on the duct routing direction, depending on the installation location. Even in such a case, since the air-conditioning member 40 is cylindrical, the inlet hole 24 can be attached below the outlet hole 25 as shown in FIGS. 2 and 3, and the suspended particles can be determined with less construction and stable. .

  The control unit 6 shown in FIG. 4 opens the shutter 44 of the air conditioning member 40 of FIGS. 2 and 3 for about several seconds at regular intervals to detect the amount of suspended particles. Depending on the amount of suspended particles detected by the dust sensor 8, the rotation speed, that is, the air volume of the air supply blower 3 and the exhaust blower 4 in FIG. For example, when the amount of suspended particles exceeds a predetermined value, the air volume of the exhaust blower 4 is increased, and the suspended particles in the room are discharged outdoors. Or the air volume of the air supply blower 3 is raised, and the fresh air removed by the outdoor side air purification filter 5 is supplied indoors.

  And the control part 6 opens the shutter 44 of the air-conditioning member 40a and the air-conditioning member 40b for about several seconds for every fixed time, and detects the amount of suspended particles. The rotation speed, that is, the air volume of the air supply blower 3 and the exhaust blower 4 can be controlled according to the amount of suspended particles detected by the dust sensor 8a and the dust sensor 8b. For example, when the amount of airborne particles exceeds a certain threshold, the airflow of the exhaust blower 4 is increased to discharge indoor airborne particles to the outdoors, or the airflow of the air supply air blower 3 is increased to actively remove airborne particles. The fresh air can be supplied to the room by being removed by the outer air cleaning filter 5.

  The air-conditioning member and the ventilator using the air-conditioning member according to the present invention are effective for applications such as a duct-type ventilator and a duct-type air conditioner for the purpose of exchanging heat between outside air and room air.
