Heating system and method for controlling ground floor negative pressure in super tall and large space buildings

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 ...

[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
