The outer air-conditioning inlet 116 is arranged between the inner ventilation outlet 114 and the inner air-conditioning outlet 113.

In this embodiment, the air conditioning and ventilating device 1 further includes a second ventilation fan set 60. Furthermore, the cabinet body 11 includes an outer ventilation inlet 117 communicating with the outer chamber 102. The second ventilation fan set 60 is arranged on the bottom of the cabinet body 11. Moreover, the outer ventilation inlet 117 and the inner ventilation outlet 114 are arranged on two sides of the bottom of the cabinet body 11. The outer air-conditioning fan 50 is located above the second ventilation fan set 60.

Please further refer to FIG. 4 and FIG. 5, which are perspective schematic views of the first ventilation fan set 30 in this disclosure. The first ventilation fan set 30 includes a first ventilation fan 31, a first valve 32 and a first valve switch 33. In this embodiment, the number of the first ventilation fan 31 is multiple. A plurality of first ventilation fans 31 are arranged in a matrix manner. The first valve 31 is combined on one side of the first ventilation fans 31. The first valve switch 33 controls the opening and closing of the first valves 32. In some embodiments, the operation of the first valve switch 33 may be performed through an automatic control.

It is worth noticing that, in one embodiment of this disclosure, the first ventilation fan set 30 further includes a first filter component 34. The first filter component 34 is combined on the side of the first valve 32 facing the inner air-conditioning fan 40 (also refer to FIG. 1) to filter the airflow entering the cabinet body 11 through the first valve 32.

Similarly, the second ventilation fan set 60 includes a second ventilation fan 61, a second valve and a second valve switch 63. In this embodiment, the number of second ventilation fan 61 is multiple. A plurality of second ventilation fans 61 are arranged in a matrix manner. The second valve 62 is combined on one side of the second ventilation fans 61. The second valve switch 63 controls the opening and closing of the second valves 62. In some embodiments, the operation of the second valve switch 63 may be performed through an automatic control.

Furthermore, the second ventilation fan set 60 further includes a second filter component 64. The second filter component 64 is combined on a side of the second valve 62 facing the outer air-conditioning fan 50 (also refer to FIG. 3) to filter the airflow entering the cabinet body 11 through the second valve 62.

Please further refer to FIG. 6, which is a schematic diagram of the airflow of the air conditioning and ventilating device 1 during the operation of ventilation and energy-saving in this disclosure. When using the air-conditioning and ventilating device 1 of this disclosure, the inner chamber 101 of the cabinet body 11 faces the specific area that needs to be heat dissipated, such as a communication apparatus room, etc.

When the specific area needs to be ventilated only, the air conditioning unit 20 does not need to start, and the first ventilation fan set 30 is in the running state. Then, the air in the specific area flows into the first ventilation fan 31 from the inner ventilation inlet 111 and enters the outer chamber 102 through the first valve 32, and then flows out to the external environment through the outer air outlet 115.

In this embodiment, the air conditioning unit 20 is provided with a second ventilation fan set 60. The second ventilation fan set 60 works together with the first ventilation fan set 30. When the second ventilation fan set 60 is in operation, external air flows into the second ventilation fan 61 from the outer ventilation inlet 117 and passes through the second valve 62, and then flows into the specific area from the inner ventilation outlet 114.

Accordingly, the air conditioning and ventilating device 1 ventilates the specific area through the first ventilation fan set 30 and the second ventilation fan set 60. Additionally, since the air-conditioning unit 20 is not running during the operation of ventilation, the air conditioning and ventilating device 1 may achieve the effect of energy saving.

Please further refer to FIG. 7, which is a schematic diagram of the airflow direction of the air conditioning and ventilating device 1 during the operation of air conditioning of this disclosure. The inner air-conditioning fan 40 and the outer air-conditioning fan 50 start running when the air conditioning is performed in the specific area, the air-conditioning unit 20. Then, the hot air in the specific area flows into the inner air-conditioning fan 40 from the inner air-conditioning inlet 112 and enters the inner chamber 101, and then passes through the air-conditioning unit 20 to form cooling air for heat exchange.

On the other hand, external air flows into the outer air-conditioning fan 50 from the outer air-conditioning inlet 116 and enters the outer chamber 102, and then passes through the air-conditioning unit 20 with heat through heat exchange, and then flows out to the outside environment from the outer air outlet 115.

Therefore, the cool air flowing out from the air-conditioning unit 20 flows into the specific area from the inner air-conditioning outlet 113 to dissipate heat in the specific area.

While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
