Problems solved by technology

[0002] On the one hand, with the improvement of people's quality of life, the requirements for the fresh air volume in the building are also constantly increasing, but the increase in the fresh air volume has led to an increase in air conditioning energy consumption
At the same time, the fresh air and exhaust air ducts of most existing building air-conditioning systems are set separately, which is not easy to recover the low-grade energy contained in the exhaust air.
On the other hand, the available space of urban buildings is becoming increasingly tight, and it is imperative to save building space. The shafts in buildings occupy a lot of space, but they have not been rationally utilized.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 Shown is a schematic structural diagram of a new exhaust shaft system according to an embodiment of the present invention, including: a fresh air metal pipe 1, one end of the fresh air metal pipe 1 is provided with a fresh fan to realize fresh air input, and the fresh air metal pipe 1 is arranged on the building exhaust Middle of Shaft 3. With the increase of floors, the ventilation volume of the building exhaust shaft 3 gradually increases. In order to adapt to the change of this ventilation volume, the cross-sectional area of ​​the building exhaust shaft 3 can change with the change of the floor, that is, the air volume. This implementation In this example, optionally, the cross-sectional area of ​​the shaft 3 increases with the increase of the floor, and this increase can be either a stepwise increase or a gradual increase. The building exha...

Abstract

The invention provides a fresh air exhausting public building ventilating shaft with a sensible heat recovering function. The fresh exhausting public building ventilating shaft comprises a building structure ventilating shaft and a fresh air metal pipe, wherein the fresh air metal pipe is arranged in the middle of the building structure ventilating shaft; a fresh air fan and an exhaust fan are respectively arranged at the top ends of the fresh air metal pipe and the building structure ventilating shaft; and a fresh air branch pipe and an exhausting branch pipe which are respectively arranged on each layer are communicated with the fresh air metal pipe and the building structure ventilating shaft. The space of the building ventilating shaft is fully used; the energy of building exhaustion can be recovered at the same time; and the sensible heat recovering function is realized.

Description

technical field [0001] The invention relates to a building ventilation shaft shared by building fresh air and exhaust air with sensible heat recovery function. Background technique [0002] On the one hand, with the improvement of people's quality of life, the requirements for the fresh air volume in the building are also constantly increasing, but the increase in the fresh air volume has led to an increase in air conditioning energy consumption. At the same time, the fresh air and exhaust air ducts of most existing building air-conditioning systems are set separately, which is not convenient for recovering the low-grade energy contained in the exhaust air. On the other hand, the available space of urban buildings is becoming increasingly tight, and it is imperative to save building space. The shafts in buildings occupy a lot of space, but they are not properly utilized. Contents of the invention [0003] In view of the above existing problems, the present invention provi...
