Embodiment 1
[0046] Such as figure 2 As shown, at least one ventilating device is arranged above the surface and below the top of the building, where the ventilating device includes a fan 1 and an air supply outlet 1 connected to the fan 1 . The cold air sent into the room by the fan 1 enters the room from the side of the middle and upper part of the building, forming a low-temperature air area in the upper part of the super-high space. After the cold wind enters, the air quality in the upper part and the indoor pressure increase, making the bottom of the super-high space a positive pressure.
[0047] In winter, the hot air generated by the indoor heat source rises and gathers in the upper part of the room. Under the action of the chimney effect, a positive pressure zone is formed in the upper part of the room, and a negative pressure zone is formed in the lower part of the room. The higher the room, the greater the negative pressure on the ground floor, and the greater the amount of cold...
Embodiment 2
[0050] Such as image 3 As shown, at least one ventilation device is arranged above the surface and below the top of the building, where the ventilation device includes a fan box 6, an air duct 10 connected to the fan box 6, and an air supply port two 9; the air supply port two 9 It is connected with the fan box 6 through the air duct 10 . The fan box 6 is connected to the temperature control system through the air volume regulating device 8, and the air volume regulating device 8 and the temperature control system are respectively connected to the microcomputer controller. The upper part forms a low-temperature air area. After the cold wind enters, the upper air quality and indoor pressure both increase, making the bottom layer of the super-high space into a positive pressure.
[0051] In winter, the hot air generated by the indoor heat source rises and gathers in the upper part of the room. Under the action of the chimney effect, a positive pressure zone is formed in the up...
