Abstract
The invention provides a building ventilating shaft for both fresh air and exhaust air and with a sensible heat recovering function. The building ventilating shaft comprises a building structure ventilating shaft body and a fresh air metal pipe arranged in the building structure ventilating shaft body; 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 body respectively; and a fresh air branch pipe and an exhaust air branch pipe arranged on each storey are communicated with the fresh air metal pipe and the building structure ventilating shaft body. The space of the building ventilating shaft is fully used; the energy of exhaust air of a building can be recovered at the same time; and the sensible heat recovering function is realized.
Description
Technical field
The utility model relates to a kind of new wind of building, air draft with sensible heat recovering function and shares the building ventilation vertical shaft.
Background technology
On the one hand, along with the raising of people's quality of the life, to the also constantly lifting of requirement of architecture indoor resh air requirement, but the increase of resh air requirement has caused the increase of air conditioning energy consumption.Simultaneously, the new wind of existing most of air conditioning system and exhaust duct all are to arrange respectively, are not easy to reclaim the low-grade energy that contains in the air draft.On the other hand, urban architecture free space day is becoming tight, and saves architectural space imperative, and vertical shaft has occupied very large space in the building, is not but reasonably utilized.
The utility model content
For the problem of above existence, the utility model provides a kind of new air draft to share vertical shaft, realizes the recycling of sensible heat energy in the air draft.
The utility model is realized by following technical scheme:
A kind of new wind and air draft share silo system, comprise the building structure exhaust air shaft, also comprise and be arranged on the middle new wind metal tube of vertical shaft, new wind metal tube and vertical shaft top are respectively arranged with new blower fan and exhaust blower, and build each layer and be respectively arranged with new wind arm and air exhaust branch pipe, the air exhaust branch pipe of these each layers and new wind arm communicate with structure exhaust air shaft and new wind metal tube respectively.
Further, the cross sectional area of described vertical shaft corresponding expansion along with the increase of building level.
Further, the cross section of described vertical shaft is along with the increase of building level has stepped expansion cross section.
Further, tube wall inboard and/or the arranged outside of described new wind metal tube have heat exchange fin.
Further, described exhaust air shaft can on-the-spotly be built system or with concrete prefabricated, comprise having smooth inwall.
The utility model is by taking full advantage of the space of vertical shaft, in conjunction with new wind metal tube and architectural space, realization air-conditioning and construction indoor and outdoor is carried out two-way ventilation, fresh wind tube adopts the higher metal material of heat conduction efficiency to make, just can carry out the sensible heat interchange of heat by metal pipe-wall when air intake and air draft like this, realize the recovery of air draft energy, also can save the fresh air pipeline Thermal insulation Expense simultaneously.
Description of drawings
Fig. 1 is that the new air draft with sensible heat recovering function shares building ventilation shaft structure schematic diagram.
1, new wind metal tube, 2, the vertical shaft air outlet, 3, the building exhaust air shaft, 4, new wind arm, 5, air exhaust branch pipe, 6, the building first floor, 7, the building intermediate layer, 8, architectural top.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Be illustrated in figure 1 as the new exhaust air shaft system architecture schematic diagram of a kind of embodiment of the utility model, comprise: new wind metal tube 1, an end of new wind metal tube 1 is provided with new blower fan, and to realize new wind input, new wind metal tube 1 is arranged on the middle part of building exhaust air shaft 3.Increase along with floor, the ventilation amount of building exhaust air shaft 3 increases gradually, in order to adapt to the variation of this ventilation volume, the cross-sectional area of building exhaust air shaft 3 can be the variation of air quantity and changing along with floor, in the present embodiment, alternatively, the area of section of vertical shaft 3 increases with floor, and this increase both can be that staged increases, and also can be gradual increase, building exhaust air shaft 3 can be enclosed construction, and exhaust blower is set to promote air draft in the top; Build each layer, comprise the building first floor 6, building intermediate layer 7 and architectural top 8, communicate with new wind metal tube 1 and building exhaust air shaft 3 by new wind arm 4 and air exhaust branch pipe 5 respectively, to realize the fresh-air ventilation of each floor.
Intermediate floor comprises all floors between the first floor and top layer in the building in the present embodiment.
Operating principle of the present utility model is as follows: new wind metal tube 1 is installed in the building exhaust air shaft 3, and its nose end extends to building exhaust air shaft 3 outer certain distances.Building exhaust air shaft 3 be hermetically-sealed construction, and vertical shaft air outlet 2 is left on its top, and it is mobile that new wind metal tube 1 and building exhaust air shaft 3 carry out the directional compression of new wind and air draft by blower fan respectively.New wind metal tube 1 can be made by the higher metal material of heat exchange efficiency, and such as steel, aluminium, copper and alloy thereof, such structure can utilize the tube wall of metal tube 1 to carry out the Exchange of apparent heat of nature in new wind advances the process that goes out with air draft, realizes the recovery of air draft energy.
As a kind of more excellent embodiment, can heat exchange fin be set by inwall and/or the outer wall at new wind metal tube 1, with further increase heat exchange area, improve the usefulness of interchange of heat.
