Description
Technical field
The present invention relates to photovoltaic plant field, relate in particular to a kind of photovoltaic power station component automatic temp. reducing device.
Background technology
Energy shortage and environmental protection are the common issue of facing mankind.For the mankind of 21 century, sunlight as a kind ofly can infinitely utilizing, the novel renewable energy of environmental protection, itself be exactly wealth.Under global energy background in short supply, the status of the regenerative resources such as solar energy is more and more important.
The core cell of photovoltaic generation is solar module at present, research shows, when silicon solar cell is operated in higher temperature, open circuit voltage declines to a great extent with the rising of temperature, the serious skew of working point that simultaneously causes charging, easily makes system undercharge and damages; The power output of silicon solar cell also declines to a great extent with the rising of temperature, causes solar module can not bring into play maximum performance.
Summary of the invention
Goal of the invention: the object of the invention is to overcome the deficiencies in the prior art provides a kind of rainwater of collecting that can utilize to the photovoltaic power station component device that cooling recycles automatically.
Technical scheme: photovoltaic power station component automatic temp. reducing device of the present invention, comprises rain collecting system, circulation temperature lowering system and automatic valve; Rain collecting system is sent into circulation temperature lowering system by the rainwater collecting by automatic valve;
Rain collecting system comprises that branch gathers rain pipe, main rainwater collection collector, communicating pipe and cistern; Branch gathers rain pipe bottom and connects main rainwater collection collector; Main rainwater collection collector bottom is by connecting cistern water inlet communicating pipe; Cistern delivery port goes out to connect automatic valve;
Circulation temperature lowering system comprises high-pressure pump, condenser and heating panel; Automatic valve is connected with high-pressure pump and condenser respectively by Y type water pipe, and high-pressure pump is connected with heating panel top and bottom mating respectively with condenser; Heating panel mates adjacent setting with photovoltaic battery panel.
Branch gathers rain pipe top three-dimensional coarse strainer is set.
Main rainwater collection collector middle part arranges supersonic liquid level inductor, bottom setup times control valve.
Supersonic liquid level sensor location is lower than cistern water inlet.
Condenser is water condenser or aerial condenser.
Cistern is connected with service water pipeline.
Operation principle of the present invention: during rainfall, rainwater is collected to branch through assembly surface and gathers rain pipe, through three-dimensional coarse strainer, filter out the leaf in water, the bulks such as architect shatter mince and then are pooled to main rainwater collection collector, first the comparatively serious early-stage rainwater of dirt enters in main rainwater collection collector, when supersonic liquid level inductor senses that rainwater increases, automatic linkage device will be opened time control valve automatically, the comparatively serious rainwater of initial stage dirt will be discharged, discharging rainfall and time can be according to local rainwater strength formula and factory building roof area calculating and setting.Early-stage rainwater is discharged rear automatic valve and is then automatically closed, then rainwater will and overflow in cistern by main rainwater collection collector communicating pipe, rainwater is opened automatic valve, by high-pressure pump, water is squeezed into heating panel to the photovoltaic battery panel processing of lowering the temperature after precipitation, and water enters condenser and carries out entering after heat exchange high-pressure pump again and recycle photovoltaic electrification component is lowered the temperature after photovoltaic electrification component being lowered the temperature by heating panel.
Beneficial effect: the rainwater that 1, utilization of the present invention collects is as cooling water, by automatic valve, enter cycle refrigeration system, by high-pressure pump, pressurize cooling water flow through heating panel and pass through condenser cool cycles and back and forth photovoltaic electrification component is lowered the temperature, effectively reduce photovoltaic electrification component surface temperature, reduce power loss, guaranteed output output.2, the mince main rainwater collection collector that drops of the bulks such as leaf in the anti-sealing of three-dimensional coarse strainer, architect shatter is set and causes obstruction.3, as long-time without rainfall branch gather rain pipe and three-dimensional coarse strainer surface can a large amount of dusts of accumulation, while therefore raining, in the rainwater at initial stage, can carry a large amount of impurity, should not use, supersonic liquid level inductor is set to be sensed when rainwater increases, automatic linkage device will be opened time control valve automatically, and the initial stage carries the rainwater of impurity and will discharge.4, supersonic liquid level sensor location prevents from ultrasonicly sensing in cistern that ripples concussion sends false command lower than cistern water inlet.5, condenser employing water condenser or aerial condenser are faster to cooling water refrigeration.6, cistern is connected with service water pipeline, rainwater in cistern after precipitation can be used as service water and uses, and during for a long time without rainfall, also can service water be poured into cistern from the water filling of service water pipeline and provide cooling water for photovoltaic power station component automatic temp. reducing device.
