[0006] 2. The difference in geometric characteristics causes the difference in the negative pressure value of the bottom layer
If the air supply does not enter from the lower edge of the roof, but enters at a lower position, that is, the air supply enters in an area with a low temperature, the air entering in this way cannot fully absorb heat and heat up, and it is still a low-temperature gas, and it will quickly Sink and enter the bottom working area, so that the purpose of increasing the temperature of the bottom working area will not be achieved

Embodiment 1

[0045] 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.

[0046] 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

[0049] 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 floor of the super-high space into a positive pressure.

Abstract

The invention discloses a bottom vacuum control heating system and method for super-large space buildings. The system comprises at least one ventilator mounted in a building above the ground and below the building top. The ventilators are connected with a temperature control system through an air volume regulator. The air volume regulator and the temperature control system are both connected with a microcomputer controller. The ventilators supply indoor cold air entering the indoor from the side of the upper middle of the building; a low temperature air area forms in the upper portion of super-large space; after the cold air enters, both quality of the upper air and indoor pressure increase, and the bottom pressure of the super-large space turns into positive pressure. A principle of the bottom vacuum control heating system and method for super-large space buildings is simple, equipment investment is low, and the system and method is easy to carry out; for the super-large space building with a heat source, the bottom negative pressure is controlled and good heating effect is achieved; the indoor waste heat is utilized, and heating energy consumption is saved.

Description

technical field [0001] The invention relates to a winter heating system and a method thereof, in particular to a heating system and a method for controlling the negative pressure at the bottom of a super-tall and large-space building in winter. Background technique [0002] Super tall and large space buildings refer to buildings with uninterrupted space inside the building, whose height direction dimension is larger than the length, width, diameter and other dimensions on the plane. In the case of the same indoor heat dissipation and the same outdoor temperature, the higher the building, the greater the negative pressure value of the ground floor. [0003] For super tall and large space buildings, the higher the room, the greater the negative pressure on the ground floor, and the greater the amount of cold air entering the room from the ground floor. Conventional heating methods cannot reduce the negative pressure on the ground floor, and thus cannot control the entry of a ...
