Description

A kind of solar photovoltaic driving ventilation evaporative cooling roofing
Technical field
The present invention relates to a kind of solar photovoltaic driving ventilation evaporative cooling roofings.
Background technique
Building energy consumption accounts for about the one third of whole society's total energy consumption, and energy consumption of air conditioning in summer is main composition portion therein Point.With the improvement of living standards, requirement of the people to living environment is higher and higher.Air-conditioning is not only universal in city, in rural area Also every household is entered already.Summer air-conditioning usage amount is very huge, and annual summer all causes a large amount of energy consumptions.
On the other hand, building enclosure temperature caused by summer high intensity solar irradiation increases, so as to cause air-conditioning refrigeration duty Increase, while outdoor convection current hot-air reaches interior by building enclosure, further increases cooling load, and then increase power consumption Amount.
Summary of the invention
Simple, good heat dissipation effect photovoltaic drive that in order to solve the above technical problem, the present invention provides a kind of structures Dynamic ventilation evaporative cooling roofing.
Technical proposal that the invention solves the above-mentioned problems is: a kind of solar photovoltaic driving ventilation evaporative cooling roofing, packet Battery, blower, water pump, reservoir, water pipe, insulation roofing, common roof are included, common roof is obliquely installed, on common roof Equipped with ladder-like sponge, insulation roofing setting is above common roof and parallel with common roof, insulation roofing and common The air duct tilted down is formed between roofing, the blower is connect with air hose, under the air outlet face air duct of air hose Port, the air duct lower port are arranged right below reservoir, and described water pipe one end connects reservoir, the setting of the water pipe other end At air duct upper port, water pipe is equipped with water pump, and the battery is electrically connected with blower, water pump respectively by electric wire;Wind Machine, which is kept watch, is sent into air hose, and the wind in air hose is sent along air duct from top to bottom to eaves, the water in pump handle reservoir Be evacuated at the top of eaves along water pipe from eaves bottom, then water be sprayed on ladder-like sponge, on ladder-like sponge from upper and After lower flowing water carries out heat convection with wind from the bottom up, remaining water body flows into reservoir again, forms a water circulation System.
Above-mentioned solar photovoltaic driving ventilation evaporative cooling roofing, further includes photovoltaic power generation plate, and photovoltaic power generation plate setting exists It is insulated roofing upper surface, photovoltaic power generation plate is electrically connected with battery;When solar radiation is strong, photovoltaic power generation plate is blower and water Pump provides electric energy, and when solar radiation is not enough to provide electric energy, the energy of whole system is provided by battery.
Above-mentioned solar photovoltaic driving ventilation evaporative cooling roofing, the water pipe other end are equipped with for keeping water sprinkling uniform Aqueduct shower nozzle.
The beneficial effects of the present invention are:
1, the present invention is equipped with photovoltaic power generation plate, and when the irradiation of summer sunlight is sufficient, photovoltaic power generation plate provides electric energy for blower and water pump, Drive whole system operating;When sunlight underexposure, the electricity that photovoltaic power generation plate provides is very few, and battery mentions for whole system For energy.
2, the present invention is equipped with insulation roofing and common roof, is insulated between roofing and common roof and forms the sky tilted down Gas channel, blower sucking wind are flowed up by air hose along the air duct between the double-deck roofing, and wind is at the top of air duct Discharge.Water pump reaches at the top of air duct from reservoir pumping along water pipe, and is uniformly sprayed to roof by aqueduct shower nozzle Ladder-like sponge on, form convection current with the wind that flows from the bottom up along air duct, the wind that blower attracts evaporates the water, water Evaporation endothermic accelerates indoor heat and transmits toward roof, and the vapor being heated with the wind is brought to outdoor, to make room Interior temperature lowers.The water for flowing to air duct bottom enters reservoir and is then evacuated to water pipe at the top of eaves by water pump again, It is sprayed to zigzag sponge through spray head, water system is formed and recycles.
Detailed description of the invention
Fig. 1 is side view of the invention.
Fig. 2 is front view of the invention.
Fig. 3 is perspective view of the invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1-Figure 3, a kind of solar photovoltaic driving ventilation evaporative cooling roofing, including photovoltaic power generation plate 1, electric power storage Pond 2, electric wire 3, blower 4, water pump 5, reservoir 6, water pipe 7, aqueduct shower nozzle 8, insulation roofing 9, common roof 10, common roof 10 Be obliquely installed, common roof 10 is equipped with ladder-like sponge 11, the insulation roofing 9 setting above common roof 10 and with it is general Logical roofing 10 is parallel, is insulated between roofing 9 and common roof 10 and forms the air duct tilted down, the blower 4 and air hose 12 connections, the air outlet face air duct lower port of air hose 12, blower 4 mainly send lower air to top along air duct Portion and water heat convection, and raising air velocity, increase evaporation capacity and evaporation rate, endothermic effect are allowed to become apparent from;It is described Air duct lower port is arranged right below reservoir 6, and described 7 one end of water pipe connects reservoir 6, and 7 other end of water pipe is arranged in sky At the upper port of gas channel, 7 other end of water pipe is equipped with for making water spray uniform aqueduct shower nozzle 8, and water pipe 7 is equipped with water pump 5, institute Battery 2 is stated to be electrically connected with blower 4, water pump 5 respectively by electric wire 3.
The setting of photovoltaic power generation plate 1 is electrically connected in insulation 9 upper surface of roofing, photovoltaic power generation plate 1 with battery 2;When sun spoke When penetrating strong, photovoltaic power generation plate 1 is that blower 4 and water pump 5 provide electric energy, when solar radiation is not enough to provide electric energy or rainy days When gas, night, the energy of whole system is provided by battery 2.
Blower 4 sucks wind and is flowed up by air hose 12 along the air duct between the double-deck roofing, and wind is from air duct Top discharge.Water pump 5 draws water from reservoir 6 and reaches at the top of air duct along water pipe 7, and is uniformly sprayed by aqueduct shower nozzle 8 Spill to the ladder-like sponge 11 on roof, on ladder-like sponge 11 from top to down flowing water with along air duct from the bottom up The wind of flowing forms convection current, and the wind that blower 4 attracts evaporates the water, and water evaporation heat absorption accelerates indoor heat and transmits toward roof, And the vapor being heated with the wind is brought to outdoor, so that indoor temperature be made to lower.It flow to the water of air duct bottom The water pipe 7 at the top of eaves is then evacuated to by water pump 5 again into reservoir 6, zigzag sponge 11 is sprayed to through spray head, forms water system System recycles.
