Abstract
The utility model discloses an underground space ventilation unit based on heat exchanger belongs to solar energy utilization and underground space ventilation combination field. Including underground space ventilation passageway and heat exchanger, the heat exchanger sets up in underground space ventilation passageway bottom, hot -water supply device is connected at the both ends of heat exchanger, its import lets in hot water, the export is flowed through heat exchanger heat transfer cooling water, the heat exchanger during operation, can be with the ventilate air heating of passageway bottom of underground space, make the air density of underground space ventilation passageway bottom reduce and follow the rising of underground space ventilation passageway until discharge underground space under the buoyancy effect that the density contrast produced, underground space ventilation this moment passageway bottom air is filled by underground space's air, last the heating, to form stable updraft in the underground space ventilation passageway, thereby play exhaust ventilation's effect. The utility model has the advantages of ventilation efficiency is high, the effect stable, the power consumption is low, with low costs, noise pollution is little, energy -concerving and environment -protective.
Description
Technical field
The utility model belongs to Solar use and underground space ventilation combines field, and in particular to one kind is based on heat exchanger
Underground space ventilation unit.
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 the one of the main reasons 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 exchanging fluid (water or air),
And recycle so as to improve solar energy overall utilization.
The Hot wet air heating of the generations such as example city integrated piping lane of the underground space even flammable explosive gas, cause the underground space
Air ambient deteriorates, and easily triggers security incident, it is necessary to set effective ventilating system.Mainly there are gravity-flow ventilation and machinery at present
Ventilation two ways, wherein gravity-flow ventilation reach ventilation purpose using hot pressing, exhaust effect by turnover open area and the two
The influence of the discrepancy in elevation, it usually needs removing shaft is built very high so that construction cost increases, and ventilation effect is also unstable；Machine
Using blower fan as ventilation equipment, the method power consumption is high, and less economical, noise pollution is big for tool ventilation.
Utility model content
For existing improvement of Natural Ventilation in Underground Space drafting efficiency is low, ventilation effect is unstable, and force ventilation power consumption it is high,
The weak point such as noise pollution is big, the utility model provides a kind of underground space ventilation unit based on heat exchanger, device tool
Have the advantages that drafting efficiency high, effect stability, consume energy low, low cost, noise pollution be small, energy-conserving and environment-protective.
The technical solution of the utility model is as follows：
Underground space ventilation unit based on heat exchanger, including underground space vent passages 2 and heat exchanger 3, the heat exchange
Device 3 is arranged at the bottom of underground space vent passages 2；The two ends connection hot-water supply device of heat exchanger 3, its import is passed through hot water,
Outlet outflow is through the heat exchange cooling water of heat exchanger 3；
When heat exchanger 3 works, the air of the bottom of underground space vent passages 2 can be heated so that underground space ventilation is logical
The atmospheric density of the bottom of road 2 reduce and rise along underground space vent passages 2 under the buoyancy lift effect that density contrast is produced until
The discharge underground space 4.
Specifically, the hot-water supply device at connection heat exchanger 3 two ends is photo-thermal device.
Specifically, the hot-water supply device at connection heat exchanger 3 two ends is the heat-exchanger rig of photovoltaic device.
The beneficial effects of the utility model：Compared with gravity-flow ventilation, drafting efficiency is higher, ventilation effect is more stable；With machine
Tool ventilation is compared, and noise pollution is small, lower, energy-conserving and environment-protective of consuming energy, simple and easy to apply；In the hot water supply at connection heat exchanger 3 two ends
Device 1 for photovoltaic device heat-exchanger rig and photo-thermal device when, also solve in solar photovoltaic technology due to photovoltaic device
Temperature raises the problem for causing the reduction of its photoelectric transformation efficiency to part in the process of running, improves solar energy composite utilization ratio.
Brief description of the drawings
The structural representation of the underground space ventilation unit based on heat exchanger that Fig. 1 is provided for the utility model.
The operating diagram of the underground space ventilation unit based on heat exchanger that Fig. 2 is provided for the utility model, wherein empty
Line arrow represents air flow.
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.
As shown in Figure 1 be the underground space ventilation unit based on heat exchanger structural representation, including the underground space ventilation
Passage 2 and heat exchanger 3, heat exchanger 3 are arranged at the bottom of underground space vent passages 2；The two ends connection hot water supply dress of heat exchanger 3
Put, its import is passed through hot water, and outlet outflow is through the heat exchange cooling water of heat exchanger 3；When heat exchanger 3 works, the underground space can be divulged information
The air heating of the bottom of passage 2 so that the atmospheric density of the bottom of underground space vent passages 2 reduces and in floating that density contrast is produced
Rise along underground space vent passages 2 under lift effect until the discharge underground space 4.Wherein connect the hot water at the two ends of heat exchanger 3
Feeding mechanism 1 can be the heat-exchanger rig of optical thermal device part or photovoltaic device.The underground space 4 is arranged on underground space vent passages 2
It is connected below and with the bottom of underground space vent passages 2, the air in the underground space 4 is empty in the bottom of underground space vent passages 2
Gas is heated the bottom air of filling underground space vent passages 2, heat exchanger continuous heating, underground space vent passages 2 when rising
Interior to form the ascending air of stabilization, so as to play a part of vented exhaust, its air flow schematic diagram is as shown in Figure 2.
The utility model proposes the underground space ventilation unit based on heat exchanger, by using heat exchanger reach ventilation effect
Really, gravity-flow ventilation efficiency had both been solved low, the unstable problem of effect, also solves force ventilation high energy consumption and noise pollution is big
Problem.
The utility model proposes the underground space ventilation unit based on heat exchanger, in the hot water at connection heat exchanger 3 two ends
Feeding mechanism 1 for photovoltaic device heat-exchanger rig and photo-thermal device when, also solve in solar photovoltaic technology due to light
Temperature raises the problem for causing the reduction of its photoelectric transformation efficiency to volt device in the process of running, improves solar energy composite using effect
