Abstract
The utility model discloses an underground space ventilation unit belongs to solar energy utilization and underground space ventilation combination field. Including heating device and fan, air inlet is connected to heating device one end, and the fan is connected to the other end, the air outlet sets up in the bottom of underground space ventilation passageway, the parallel connection machine of giving a dinner for a visitor from afar, the ambient air that heating device heating let in from air inlet, the air outlet that underground space ventilation passageway bottom was delivered to through the fan to the air that is heated discharges, and the temperature rising density that makes the cold air with the mode through the heat exchange behind the cold air mixing in the underground space ventilation passageway reduces and follow the rising of underground space ventilation passageway until discharge underground space under the buoyancy effect that the density contrast produced. The utility model has the advantages of reinforce the underground space natural draft effect, reduce the mechanical draft energy consumption, it is energy -concerving and environment -protective, reliable and simple, can also improve the solar energy comprehensive utilization ratio during heat transfer device of heating device borrowed light calorimeter spare or photovoltaic device.
Description
Technical field
The utility model belongs to Solar use and underground space ventilation combines field, and in particular to a kind of underground space is led to
Wind apparatus.
Background technology
Solar photovoltaic technology is widely used, but photovoltaic module in the process of running temperature raise cause it
Photoelectric transformation efficiency reduction, this is one of the major reason for limiting its further genralrlization.For so that in photovoltaic module running
It is maintained within the scope of certain temperature, the waste heat that photovoltaic module is produced can be taken away by heat catalysis (water or air),
And recycle so as to improve solar energy overall utilization.
The Hot wet air heating that the underground space (such as city integrated piping lane) is produced even flammable explosive gas, cause the underground space
Air ambient deteriorate, easily trigger security incident, it is necessary to set effective ventilating system.Mainly there are gravity-flow ventilation and machine at present
Tool ventilation two ways, wherein gravity-flow ventilation need not set special ventilation equipment, and simple structure, power consumption is few, but gravity-flow ventilation
Shortcoming be small unstable, energy, using above there is significant limitation；Force ventilation need to use blower fan as ventilation equipment,
Power consumption is high, and less economical, noise pollution is big.
Utility model content
To make up the deficiency of existing underground space draft type, the utility model provides a kind of underground space ventilation unit,
There is ventilation low cost, energy consumption is low for ventilation, energy-conserving and environment-protective.
The technical solution of the utility model is as follows：
Underground space ventilation unit, including air heating apparatus 1, air intake 2, blower fan 3 and air outlet slit 4；The sky
The one end of gas heater 1 connects air intake 2, other end connecting fan 3；Air outlet slit 4 is arranged at underground space vent passages 5
Bottom, and connecting fan 3；
Air heating apparatus 1 heat the surrounding air being passed through from air intake 2, and heated air delivers to ground through blower fan 3
Discharged at the air outlet slit 4 of the lower bottom of space ventilator passage 5, passed through after mixing with the cold air in underground space vent passages 5
The mode of heat exchange makes air temperature high-density reduce and logical along the underground space under the buoyancy lift effect that density contrast is produced
Wind passage 5 rises until the discharge underground space 6.
Specifically, the air heating apparatus 1 are photo-thermal device.
Specifically, heat-exchanger rig of the air heating apparatus 1 for photovoltaic device.
The beneficial effects of the utility model：Improvement of Natural Ventilation in Underground Space effect is enhanced, force ventilation energy consumption is reduced, saved
Can be environmentally friendly, it is simple and easy to apply；In heat-exchanger rig of the air heating apparatus using photo-thermal device or photovoltaic device, the sun is also solved
Due to photovoltaic device, temperature raises the problem for causing the reduction of its photoelectric transformation efficiency in the process of running in energy photovoltaic power generation technology,
Improve solar energy composite utilization ratio.
Brief description of the drawings
The structural representation of the underground space ventilation unit that Fig. 1 is provided for the utility model.
The fundamental diagram of the underground space ventilation unit that Fig. 2 is provided for the utility model, wherein dotted arrow represent empty
Air-flow to.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings, to this reality
It is further elaborated with new.
The structural representation of the underground space ventilation unit for being provided for the utility model as shown in Figure 1, including air heating
Device 1, air intake 2, blower fan 3, air outlet slit 4, underground space vent passages 5 and the underground space 6, surrounding air is by being connected to
The air inlet heater 1 of air intake 2 of the one end of air heating apparatus 1, by being connected to after being heated through air heating apparatus 1
The blower fan 3 of the other end of air heating apparatus 1 delivers to the air outlet slit 4 of the bottom of underground space vent passages 5, is discharged to the underground space
Mix with the cold air in underground space vent passages 5 in vent passages 5, the cold air in underground space vent passages 5 is added
Heat, density reduces, and rises along underground space vent passages 5 in the presence of the buoyancy lift that density contrast is produced, and now underground is empty
Between the bottom air of vent passages 5 filled by the air in the underground space 6, continue empty to heat is sent into underground space vent passages 5
The ascending air of stabilization, so as to play a part of vented exhaust, its air flow will be formed in gas, underground space vent passages 5
As shown in Figure 2.
The utility model proposes underground space air exhausting device, by air heating means heats air, and with blower fan will
Air after being heated delivers to underground space vent passages inner bottom part, enhances improvement of Natural Ventilation in Underground Space effect, reduces machine
Tool ventilation energy consumption, energy-conserving and environment-protective are simple and easy to apply.
The utility model proposes underground space ventilation unit, air heating apparatus for photovoltaic device heat-exchanger rig or
During photo-thermal device, also solve in solar photovoltaic technology that temperature is raised and causes it in the process of running due to photovoltaic device
The problem of photoelectric transformation efficiency reduction, improves solar energy composite utilization ratio.
The above tells preferred embodiment only of the present utility model, is not used to limit the utility model.It should be pointed out that
On the premise of without departing substantially from the utility model spirit and its essence, those of ordinary skill in the art make according to the utility model
Various corresponding changes and deformation etc., should all be included within protection domain of the present utility model.
