This solution only requires one fan 300 and one third air duct 130 (so that the wall only needs to have a through hole connecting the indoor and outdoor), and its structure is simple and the manufacturing cost is low.

[0040] The heat exchanger 400 may be disposed in the first air duct 110; or the heat exchanger 400 may be disposed in the second air duct 120; all of the above can achieve the purpose of the present application, and their purpose does not deviate from the design concept of the present utility model, and will not be repeated here, and all should fall within the protection scope of the present application.

[0041] The following is a detailed description using an example in which the heat exchanger 400 is disposed in the second air duct 120 , the second air outlet 320 of the fan 300 is connected to the second air duct 120 , and the first air outlet 310 of the fan 300 is connected to the first air duct 110 .

[0042] In some examples, the air handling device has a first mode, a second mode, a third mode, a fourth mode, and a fifth mode.

[0044] For the technical solution in which the first air outlet 310 is the air inlet and the second air outlet 320 is the air outlet, the first mode is the fresh air mode. At this time, the outside air enters the second air duct 120 from the third air duct 130 through the first air outlet 140, the first air duct 110 and the fan 300 in sequence, and then is blown into the room through the second air duct 120 (see Figure 1 In this process, the heat pump system of the air handling equipment can also be operated to exchange heat between the fresh air and the heat exchanger 400, thereby reducing the temperature difference between the fresh air and the indoor air.

[0045] For the technical solution in which the first air outlet 310 is the air outlet and the second air outlet 320 is the air inlet, the first mode is the exhaust mode. At this time, the indoor air enters the third air duct 130 from the second air duct 120 through the fan 300, the first air duct 110 and the first air outlet 140 in sequence, and then is blown to the outside through the third air duct 130 (at this time, the airflow direction is Figure 1 The direction opposite to the airflow direction shown by curve a in FIG.

[0046] In the second mode: the first switch door structure 210 is controlled to open the first air duct 110 , the fourth switch door structure 240 is controlled to open the second air outlet 150 , the second switch door structure 220 is controlled to close the second air duct 120 , and the third switch door structure 230 is controlled to close the first air outlet 140 .

At this time, the indoor air enters the third air duct 130 from the first air duct 110 through the fan 300, the second air duct 120 and the second air outlet 150 in sequence, and then is blown to the outside through the third air duct 130 (see Figure 1 The airflow direction is shown by curve b in FIG.

[0048] For the technical solution in which the first air outlet 310 is the air outlet and the second air outlet 320 is the air inlet, the second mode is the fresh air mode. At this time, the outside air enters the first air duct 110 from the third air duct 130 through the second air outlet 150, the second air duct 120 and the fan 300 in sequence, and then is blown into the room through the first air duct 110 (the airflow direction at this time is Figure 1 The direction opposite to the airflow direction shown by curve b in FIG.

[0049] In the third mode: the heat pump system of the air handling equipment is controlled to operate, the first switch door structure 210 opens the first air duct 110, the second switch door structure 220 opens the second air duct 120, the third switch door structure 230 opens the first air outlet 140, and the fourth switch door structure 240 closes the second air outlet 150.

[0050] For the technical solution in which the first air outlet 310 is the air inlet and the second air outlet 320 is the air outlet, the third mode is the fresh air + heat exchange mode. At this time, the outside air enters the second air duct 120 from the third air duct 130 through the first air outlet 140, the first air duct 110 and the fan 300 in sequence, and then is blown into the room through the second air duct 120. The fresh air exchanges heat with the heat exchanger 400 during the process of passing through the heat exchanger 400 (see Figure 1 The indoor air enters the second air duct 120 through the first air duct 110 and the fan 300, and then is blown into the room through the second air duct 120. The indoor air exchanges heat with the heat exchanger 400 during the process of passing through the heat exchanger 400 (see Figure 1 The airflow direction shown by curve c in Figure 2 This solution can reduce the temperature difference between fresh air and indoor air.

[0051] For the technical solution in which the first air outlet 310 is the air outlet and the second air outlet 320 is the air inlet, the third mode is the exhaust + heat exchange mode. At this time, the indoor air enters the first air duct 110 from the second air duct 120 through the fan 300, and then a part of it enters the third air duct 130 from the first air outlet 140, and is blown to the outside through the third air duct 130 (the airflow direction at this time is Figure 1 The other part is blown into the room through the first air duct 110 (the air flow direction at this time is Figure 1 The opposite direction of the airflow direction shown by curve c in Figure 2 In this mode, the indoor air exchanges heat with the heat exchanger 400 during passing through the heat exchanger 400.

[0053] For the technical solution in which the first air outlet 310 is the air inlet and the second air outlet 320 is the air outlet, the fourth mode is the exhaust + heat exchange mode. At this time, the indoor air enters the second air duct 120 from the first air duct 110 through the fan 300, and then a part of it enters the third air duct 130 from the second air outlet 150, and is blown to the outside through the third air duct 130 (see Figure 1 The other part is blown into the room from the second air duct 120 (see Figure 1 The airflow direction shown by curve c in Figure 2 In this mode, the air passing through the heat exchanger 400 exchanges heat with the heat exchanger 400.

[0054] For the technical solution in which the first air outlet 310 is the air outlet and the second air outlet 320 is the air inlet, the fourth mode is the fresh air + heat exchange mode. At this time, the outside air enters the second air duct 120 from the third air duct 130 through the second air outlet 150 (the air flow direction at this time is Figure 1 The indoor air enters the second air duct 120 (the air flow direction is opposite to the direction of the air flow shown by the curve b in FIG. 1 ). Figure 1 The opposite direction of the airflow direction shown by curve c in Figure 2 The two parts of air then pass through the fan 300 and enter the first air duct 110, and are blown into the room through the first air duct 110. In this mode, the air passing through the heat exchanger 400 exchanges heat with the heat exchanger 400. This solution can reduce the temperature difference between the fresh air and the indoor air.
