The operation and effects of the energy-saving vertical air cycle machine of the present invention to which the twin-shaft motor twin fan is applied will be described below.
As an example, the energy-saving vertical air cycle machine of the present invention, which is applied to a twin-shaft motor twin fan, is installed in a school classroom. In this case, the rear face of the housing 10 is located on the classroom window side. The first outdoor air supply port 13 and the second outdoor air supply port 14 provided on the rear surface of the casing 10 of the floor air conditioner are connected to the air supply connection pipe and exposed to the outside of the classroom window, and the outdoor air discharge port 15 is connected to the air discharge connection pipe and exposed to the outside of the classroom window.
In this state, when ventilation of the room air is required as the concentration of carbon dioxide in the room of the school building increases, the air supply double fan assembly 40 and the air exhaust fan assembly 50 are operated, respectively. By the operation of the air supply double fan assembly 40, the air supply flow is generated, the outdoor air outside the classroom flows into the room through the first outdoor side air supply port 13 and the second outdoor side air supply port 14 of the housing 10, respectively, and flows into the room through the first front side air supply fan 42 of the air supply double fan assembly 40 formed to the outside of one side of the first outdoor side air supply port 13-first rear side air supply pipe 60-first heat exchange device 20-flow path formation exhaust pipe 80, and the outdoor air flows into the room through the second air supply fan 43 of the air supply double fan assembly 40 formed to the outside of the other side of the second outdoor side air supply port 14-second rear side air supply pipe 70-second heat exchange device 30-flow path formation exhaust pipe 80, and flows into the room through the second air supply fan 43 of the air supply double fan assembly 40 formed to the outside of the other side of the second side of the housing 10.
At the same time, by the operation of the exhaust fan assembly 5, the flow of the exhaust air will be generated, and the room air will flow into the plurality of indoor side exhaust ports 12 provided on both sides of the casing 10, and will be discharged to the outside through one side indoor side exhaust port 12-the first heat exchange device 20-the flow path formation exhaust duct 80-the exhaust fan 52 of the exhaust fan assembly 50-the outdoor side exhaust port 15, while the room air will be discharged to the outside through the other side indoor side exhaust port 12-the second heat exchange device 30-the flow path formation exhaust duct 80-the exhaust fan 52 of the exhaust fan assembly 50-the outdoor side exhaust port 15. As described above, the room air is discharged to the outside, and the outdoor air is supplied to the room, and the room air of the building is ventilated during this process. The indoor air and the outdoor air pass through the first heat exchanging device 20 and exchange heat with each other, and the indoor air and the outdoor air pass through the second heat exchanging device 30 and exchange heat with each other, so that heat loss of the classroom is reduced, and the indoor air of the classroom is ventilated.
With the bypass unit 90, the indoor air is bypassed when it is rapidly discharged to the outside without passing through the first and second heat exchange devices 20 and 30. When the bypass is performed, the air supply double fan assembly 40 and the exhaust fan assembly 50 are operated in a state in which the bypass pipe 92 is opened by the opening/closing unit 93. By the operation of the exhaust fan assembly 50, an exhaust flow is generated, and room air flows into the plurality of bypass holes 91 respectively provided at both sides of the housing 10 and is discharged to the outside through the one side bypass hole 91-the flow path forming exhaust duct 80-the exhaust fan 52 of the exhaust fan assembly 50-the outdoor side exhaust port 15, and at the same time, the room air is discharged to the outside through the other side bypass hole 91-the flow path forming exhaust duct 80-the exhaust fan 52 of the exhaust fan assembly 50-the outdoor side exhaust port 15. At the same time, the exhaust gas does not flow through the first and second heat exchange devices 20 and 30, and thus, the contaminated air is rapidly discharged to the outside. The flow of the air supply double fan assembly 40 is as described above. On the other hand, when bypass is performed, only the exhaust fan assembly 50 is operated.
As described above, the present invention includes the casing 10, the first heat exchanging device 20, the second heat exchanging device 30, the air supply double fan assembly 40, the exhaust fan assembly 50, the first rear side air supply duct 60, the second rear side air supply duct 70, and the flow path formation exhaust duct 80, and thus, the indoor air flows in through the plurality of indoor side exhaust ports 12 provided at both side surfaces of the casing 10 and is discharged through the outdoor side exhaust ports 15 provided at the upper portion of the rear surface of the casing 10, and the outdoor air flows in through the first outdoor side air supply port 13 and the second outdoor side air supply port 14 provided at the rear surface of the casing 10 and flows into the room through the indoor side air supply part 11 provided at the front surface of the casing 10, thereby effectively ventilating the indoor air.
In the present invention, the outdoor air discharge port 15 through which indoor air is discharged to the outside and the first and second outdoor air supply ports 13 and 14 through which outdoor air flows to the inside are provided at the upper portion of the rear surface of the casing 10, respectively, so that the operation of installing the indoor unit in the conventional building is simple and convenient by installing the indoor unit in the vicinity of the indoor window of the building and connecting the air supply connection pipe and the air discharge connection pipe through the window.
In the present invention, since the first rear side air supply duct 60 and the second rear side air supply duct 70 for supplying the outdoor air to the indoor are provided on both sides of the flow path formation exhaust duct 80 for discharging the indoor air to the outdoor, the structure of the exhaust flow path for discharging the indoor air to the outdoor and the structure of the supply flow path for supplying the outdoor air to the indoor are compact.
Also, in the present invention, in case that the indoor air is rapidly polluted, the polluted indoor air can be rapidly ventilated by the bypass movement of the bypass unit 90, thereby minimizing the exposure to the polluted indoor air.
